The Safe America Foundation suggests texting as a way of communication. Doctor reveals the horrors Italian medics are facing in overwhelmed hospitals where dying patients are being left untreated as experts warn UK and US are just two weeks behind Italy and the public are not SCARED enough, An intensive care doctor in northern Italy has described the scale of the crisis Devastating wind storms. This kind of landslide is called an earthquake-triggered landslides. These quakes are capable of magnitudes from 7 to over 9. This fundamental tool for earth scientists, maps show map units, faults and folds, cross sections, and other regional or local features, depending on map scale. The most recent hit roughly 2,700 years ago. Notice the Seattle Fault Zone bounding the Seattle Basin to the south. Large earthquakes are less common but can cause significant damage to the things we count on in everyday life, such as buildings, roads, bridges, dams, and utilities. The seismic mapping had cost millions of dollars far beyond what most geologists on a government budget could scrape together. The southern Whidbey fault is unlike more visible faults on the West Coast. Kristin D. Morell 1 *, Christine Regalla 2, Lucinda J. Leonard 3, Colin Amos 4, Vic Levson 5. The Seattle Fault is also likely to create a tsunami that would inundate Harbor Island and much of SODO, Interbay, and the waterfront. Kelsey and others (2004 #7651) compared sea-level histories at two salt marshes that straddle a northeast strand of the southern Whidbey Island fault zone: Crockett Marsh (site 572-1) located north of the northeastern fault strand is 8 km north of Hancock Marsh (site 572-2), south of the fault strand. The Westport area is now the first in North America to have acommunity vertical evacuation structure, a building strong enough to resist earthquake and tsunami wave forces and give people a platform above the expected wave heights. Standing becomes almost impossible as the jolts turn to rolling waves. HomePrograms and ServicesGeologyGeologic Hazards. Sometimes Geologists can use the offset land surface to understand how much the fault moved during the earthquake. The term active can have different meanings. This is an active fault.. They didnt grow up here, they havent heard this story. This kind of grouping gives us information about how common earthquakes might be and how large an area may be affected. The fault probably originated during the early Eocene as a dextral strike-slip fault along the eastern side of a continental-margin rift. These and other problems led to the search for a scale that was based on the physical processes that happen during an earthquake. And being ready means being able to support yourself, your loved ones, your neighborhood for 2 weeks. Recent geologic mapping by Washington State Department of Natural Resources (DNR) geologists reveals that this major fault zone extends through the Snoqualmie River valley in the vicinity of Carnation, Fall City, and North Bend. View Earthquake Map Faults Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. A normal fault occurs when two blocks are pulled away from each other. For several years, scientists pondered where this important regional fault zone continues southwestward from its mapped location in the Everett area. Under a scenario played out in a 2019 U.S. Department of Homeland Security study, state-maintained bridges would be severely damaged, leaving them unusable for months or years. You can look at different geological hazard mapson the website of the Department of Natural Resources. The southern Whidbey Island fault should be considered capable of generating large earthquakes (Ms ?? M 7.4 Scenario Earthquake - Southern Whidbey Island fault-southern Overview Interactive Map Regional Information Impact ShakeMap Technical Origin Download Event KML Earthquakes Hazards Data & Products Learn Monitoring Research M 7.4 Scenario Earthquake - Southern Whidbey Island fault-southern 2017-05-12 20:14:09 (UTC) 48.036N 122.452W This means that a large area feels the shaking, but the intensity is less than a similar shallow earthquake. Most faults in Washington are a mix of a strike-slip fault and a thrust or reverse fault. This is sometimes called "The Big One" by news media. Coupeville, WA 98239, Main Line:
The Cascadia subduction zone along the Washington and Oregon coast is one of the biggest hazards to our state and is a good examples of this kind of fault. The Cascade block to the northeast is floored by diverse assemblages of pre-Tertiary rocks; the Coast Range block to the southwest is floored by lower Eocene marine basaltic rocks of the Crescent Formation. The Cascadia subduction zone just off the Washington coast is this kind of fault and is one of the largest geologic hazards to our state. Contact Us, Whidbey Office
Learning earthquake faults around where we live is a first good way to prepare the next devastating earthquake. If a large earthquake happens, be prepared for many more earthquakes. By sampling sediment from the marsh to the beach berm, Sherrod and his research partner, Harvey Kelsey, developed a timeline of the oceans climb. Even when the location of a fault is known, there is much additional work to determine how hazardous it may be. It will happen; we dont know when.. Each type has different kinds of earthquakes. The South Whidbey Island Fault is also dangerous. Hey Biden! The buildings sank when ground shaking weakened the underlying sediments. In 2017, he began studying the possible aftermath of a major SWIF quake. Photo by G.K. Gilbert, from the Steinbrugge Collection of the UC Berkeley Earthquake Engineering Research Center. The Southern Whidbay Island Fault represents another major earthquake threat for Seattle and its residents. This movement happens because stress builds up as tectonic plates move. The continued movement along faults over millions of years can build mountains, tear a continent apart, and move tectonic plates thousands of miles. The southern Whidbey Island fault: An active structure in the Puget Lowland Washington, Geological Society of America Bulletin 1996;108;334-354. Both studies suggested that the SWIF Hold on to any sturdy shelter until the shaking stops. These include (from north to south, see map) the: Devils Mountain Fault Strawberry Point and Utsalady Point faults Southern Whidbey Island Fault (SWIF) Rogers Belt (Mount Vernon Fault/Granite Falls Fault Zone) Cherry Creek Fault Zone Rattlesnake Mountain Fault Zone Seattle Fault Tacoma Fault Saddle Mountain Faults The map also shows potentially active faults from a separate 2014 report (click here to download). #4747 Blakely, R.J., Wells, R.E., and Weaver, C.S., 1999, Puget Sound aeromagnetic maps and data: U.S. Geological Survey Open-File Report 99-514. The DNR team found that the Seattle fault is intercepted by the southern Whidbey Island fault zone in the vicinity of Fall City. This website uses cookies to improve your experience while you navigate through the website. Landslides can be caused by strong ground shaking during an earthquake.

Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Seconds later, its as if Whidbey Island is trapped in a cocktail shaker, lurching back and forth. A drill rig left of the blockade is collecting data about the failure. Scientists dont know. Shallow faults produce earthquakes in the upper 18 miles (30 kilometers) of the Earths crust. Over time, fault movement has created some interesting geologic features. Each of these aftershocks would be a significant earthquake if it happened on its own. The northwest-trending southern Whidbey Island fault zone occurs along a significant terrane boundary between basement blocks underlain by Eocene marine basalts of the Coast Range province to the southwest and pre-Tertiary metamorphic rocks of the Cascades province to the northeast. The map is from a, This car was parked on sand during the 2011 earthquake in Christchurch, New Zealand. One of the best views of SWIF should be from Grand Avenue Park in Everett. It startled Johnson that such massive faults had gone undetected for so long. Photo from, Liquefaction can be a big problem. A pair of scientists with the U.S. Geological Survey first theorized that a fissure between two major blocks of the earths crust might run through this slice of Puget Sound. Around Puget Sound, it seems everyone knows about The Big One, the potential magnitude 9.0 Cascadia Subduction Zone megaquake some scientists say is due any day. One of these cracks appeared along the pathway around Green Lake. A lock () or https:// means youve safely connected to the .gov website. The tsunami becomes taller as the ocean becomes shallow. Keaton and Perry (2006 #7653) excavated two trenches on the south end of the Brightwater treatment plant (KP1 site 572-3, and KP2 site 572-4). Learn how your comment data is processed. 2 0 obj
Clicking on the map will download the publication. Charles Richter and Beno Gutenberg discovered that for every magnitude of earthquake, there are about ten times more earthquakes of the next lower magnitude. Its just the way scientists work, he said. An earthquake occurs when rock inside the Earth moves or breaks. Sherrod remembers his son, age 5 at the time, playing with toy trucks on the mossy banks of the marsh while the scientists worked. Someone screams. Expect and help to extinguish fires. Because after a region-wide event, it could take that long for help to come from the rest of the country and world. Unlike The Big One, scientists who have studied the southern Whidbey fault have far less understanding of when the next sudden shift might hit. In this photo, visitors to Green Lake Park near Seattle, Washington, have parked their bicycles as they look at the cracks made by the April 1949 earthquake. Brick chimneys cascade off rooftops. This part of the Japanese coast had not seen this type of seismic rupture in some 800 years, and what failed was that walls built to keep tsunami waves were not high enough. The southern Whidbey Island fault (SWIF) stretches from the vicinity of Victoria, B.C., across Puget Sound as far as the Cascade Range. An official website of the United States government. Stay inside until the shaking stops and it is safe to go outside. We work closely with the Washington Emergency Management Division, the Washington Seismic Safety Committee, and the Federal Emergency Management Agency to ensure that the best-available science is used in the development of hazard mitigation plans. This movement created a tsunami in Puget Sound and triggered a large landslide into Lake Washington. Many landslide-prone areas of Washington are also located near active faults. On a brilliant November day, Sherrod took in the panorama from the parks bluff. Visit our School Seismic Safety page for more information. @\;L;=}%FC*l $@ 4x: 888O~xrsxx'/*rGRF\gI%~x(G-^-hjjq

sRITgZf>,e}iI5,F_ADGc?f e@L. Strabge sounds very good report thanks a lot. Evacuate to higher ground if you are near a large body of water. Most damage and loss of life in earthquakes is a result of ground shaking. Tsunamis triggered by earthquakes usually require at least a M7 event. Others, like the Seattle fault and southern Whidbey Island fault zone, cross under major cities and pose a significant hazard. <>/XObject<>/ExtGState<>/Pattern<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>
Theres approximately a 14% chance of another approximately M9 earthquake occurring in the next 50 years. This means that a tsunami made by an earthquake on the Cascadia subduction zone will start to impact the Washington coast in less than 15 minutes. Additionally, because the continent moves up and over the ocean plate, large amounts of sea water are displaced and cause damaging tsunamis. and the Red Cross will be there to care for them. Both types of faults can cause ground shaking during an earthquake and may cause permanent deformation of the ground. The shaking can also cause landslides, surface ruptures, ground cracks, liquefaction, tsunamis, and seiches (standing waves). When earthquakes occur on faults that reach the Earths surface, the ground may rupture. At a downtown coffee shop, the mugs begin to chatter. Often this cracking happens because a soft part of the ground liquefies during the shaking. , * NOTE: Hazard maps for each jurisdiction will only be included if that jurisdiction is at risk to that hazard., Copyright Island County. Photo from, This image shows the how the 1700 AD tsunami from the Pacific Northwest crossed the Pacific Ocean. And while scientists keep digging for more information and more situational awareness of what we face, the other problem is human. Videos: Strong M6.0 earthquake rattles Mindanao in the Philippines, Dramatic earthquake increase in Hawaii! The fault's length depends on whom you ask, Sherrod said. An increase of 2 means that ~1,000 times more energy is released. By Julia-Grace Sanders The Everett Herald May 14, 2021 2:40 pm, Luella Meaux: November 21, 1929 January 21, 2023, Claudia Anderson: October 1, 1939 January 31, 2023, Chieko Yamane Miller: July 26, 1936 February 16, 2023, Guarding the flock: Chicken farms rely on specialized dogs, Flying colors: Irish artist finds success on Whidbey. The video is also available in Spanish and there is a fun activity/coloring book that can be found here. Seattle Fault and Whidbey Faults HAZARD MAPS As part of the Hazard Mitigation Planning process, mapping of the hazards that have the potential to affect the jurisdiction is performed using geographic information systems (GIS) software. Maps. The study of seismic waves is called seismology and has allowed scientists to learn much about the internal structure of the Earth. The SWIF was first recognized and mapped at a regional scale by Gower and others (1985) on the basis of gravity and aeromagnetic anomaly maps. Strait of Juan de Fuca Fault Map The Puget Sound faults under the highly populated Seattle and Puget Sound region of Washington state form a regional network of interrelated seismologic geologic faults. The risk is complicated, but there are millions of people who live in the Seattle area, said Forson. All faults, regardless of size, can be dangerous if they rupture. Volcanic eruptions. Photo courtesy of MOHAI (neg. If folding on the Little Bear Creek lineament resulted in one or two of unconformities, the poorly constrained timing of the earthquakes is younger than 12,000 yr BP and older than about 2,850 cal yr BP. Like other faults, when enough stress builds up, the megathrust will rupture. Faults can also be grouped based on what part of the crust they occur in. Stratigraphy and diatom assemblages of the marsh cores suggest Crockett Marsh underwent a 12 m of abrupt uplift relative to sea level at a time that relative sea level remained the same at Hancock Marsh. The strength of ground shaking (called strong motion by seismologists) usually decreases with distance from the earthquake source. It is a qualitative scale that ranges from IXI (1-11) and measures the amount of damage caused by an event. Avoid stopping near or under buildings, trees, overpasses, or utility wires. If everyone tries to use their cell phones, it can overload the system. HOLOCENE FAULT SCARPS AND SHALLOW MAGNETIC ANOMALIES ALONG THE SOUTHERN WHIDBEY ISLAND FAULT ZONE NEAR WOODINVILLE, WASHINGTON By Brian L. Sherrod1, Richard J. Blakely2, Craig Weaver1, Harvey Kelsey3, Elizabeth Barnett1, and Ray Wells4 1 U.S. Geological Survey, Dept. Wagner and Wiley (1983 #6230) and Wagner and Tomson (1987 #6249) mapped and briefly discussed offshore parts of this fault zone and also used the name "southern Whidbey Island fault." It may not be possible to find water, fuel, or food until services are restored days or even weeks after the event. The marshy deposits are about a meter higher at Lake Hancock. Stories from tribes near Seattle have also helped us to learn that the last earthquake on the Seattle fault was about AD 900950. Even if the earthquake is too small to be felt by people, seismographs can detect it. It could also create dangerous currents and hazards to the north including Everett. This means that the internet, your cell phone, grocery stores, and gas stations may also not work. But it didnt. The biggest one is called the South Whidbey Island fault, and it's thought to run from Victoria, B.C., through Woodinville and possibly beyond. In fact, until the 1980s, no one knew SWIF existed. Here, were looking at one of the bigger faults in the region, he said. Even when an earthquake happens on a fault that doesnt reach the surface, the ground can still show signs of cracking. Landslide at Salmon Beach was triggered by the 1949 Tacoma earthquake and caused a tsunami. 4 0 obj
Ground shaking is a hazard near the epicenter of an earthquake and also in areas far from the earthquake where amplification occurs. Disoriented drivers wonder whats wrong with their cars, then realize something much bigger is amiss. One model suggests it extends to about 30 miles east of Yakima. In some areas getting up a hill to higher ground will be difficult. Third, the South Whidbey Island Fault running from northwest to southeast of the southern tip of the island. The Straight Creek fault in the Cascade Range is an example of this kind of fault and has ~5060 miles of movement across it. California Geological Survey. The years have gone by. Within this rich oral history there are many references to events like earthquakes and tsunamis. This map is from a 2007 report on the seismic design categories in Washington. Then the world rattles up and down. Every year Western. South Whidbey Island Fault Earthquake Scenario: 7.4 Magnitude Buildings Damaged: 320,776 Fatalities: 90 - 432 Injuries: 2,920 - 7,361 Economic Loss: $15,590,000,000 SeaTac Fault Earthquake Scenario: 7.2 Magnitude Buildings Damaged: 375,954 Fatalities: 16 - 123 Injuries: 1,394 - 3,404 Economic Loss: $13,400,000,000 Tacoma Fault Geologists are constantly trying to better understand the faults in our state. Years ago, Howard Gower and James Yount came to the Puget lowlands to study earthquake risks and stumbled on what appeared to be a fault in Island and Snohomish counties. A 2014 map shows what we know about the age of faults in Washington. PO Box 5000
The trenches exposed glacial deposits disrupted by faults and liquefaction features. Swarm of hundreds of small earthquakes rattle Vancouver Island. Jump from 60 to 600 per week in just 5 years in Pahala, Is the Cascadia Subduction Zone about to blow? The southern Whidbey Island fault, and several others, were exposed for the first time from a camouflage of forest, ocean and glacial sediment. Faults are features in the Earths crust where rock periodically breaks and moves, releasing seismic energy and creating an earthquake. Know what other hazards you might face. Part 2 will be full Martial Law and mandatory vaccines? Restoring tap water to some homes could take over a year. Black lines show the South Whidbey Island Fault Zone, the Seattle Fault Zone and the Tacoma Fault Zone. DO NOT get in a doorway. So they dont necessarily know the threats they face.. 552 - Hood Canal fault zone (Class B) 570 - Seattle fault zone 572 - Southern Whidbey Island fault zone 575 - Saddle Mountain faults 581 - Tacoma fault zone. A national credit rating service has improved its opinion of WhidbeyHealths financial future. By clicking Accept, you consent to the use of ALL the cookies. South Whidbey Island Fault (SWIF) M7.4 Earthquake Scenario Fire (Vegetation Condition Class) . A special type of shallow fault, called a subduction zone or megathrust, occurs where an oceanic plate moves beneath a continental plate. This new method allows geologists to see through trees and vegetation to find new faults. The fault zone is up to 57 km, correlates with gravity and magnetic anomalies (Finn and others, 1991 #4753; Blakely and others, 1999 #4747), and has been interpreted as a complex zone of transpressional deformation (Johnson and others, 1996 #4751). Another big one is expected, and it could be devastating. The crustal faults the Seattle Fault, the South Whidbey Island Fault, the Tacoma Fault those are less well known, said Forson. The southern Whidbey Island fault zone (SWIF) is a mostly concealed, northwest-trending structure extending across southern Whidbey Island toward Vancouver Island (Figures 1 and 2). This is called liquefaction and is discussed in the next section. Get On The List To Receive Your Daily Dose Of Weird News And Amazing Phenomena. One of the most important new technologies for finding faults (and landslides too) is called lidar. Radiocarbon dating and other paleoseismic methods have also confirmed this date. The evidence shows each lake rests on different free-floating jigsaw pieces of planetary crust, separated by the southern Whidbey Island fault. Notable earthquakes in bold happened in Washington. (Andy Bronson / The Herald). The northwestern part of the fault zone forms the northeastern limit of the Port Townsend basin (Brocher and others, 2001 #4718). These combination faults are called oblique faults and include the Seattle fault, southern Whidbey Island fault zone, and DarringtonDevils Mountain fault zone. America is going to be punished just like the rest of the world. Washington State Earthquake Hazard Map. . Below you will find links to view and download hazard maps created for each jurisdiction included in the current mitigation planning process. An earthquake along the southern Whidbey Island fault reshaped the land some 2,700 years ago. The experts say few are ready. This northwest-trending fault comprises a broad (as wide as 6-11 km), steep, northeast-dipping zone that includes several splays with inferred strike-slip, reverse, and thrust displacement. These cookies will be stored in your browser only with your consent. After the shaking stopped the sand regained its strength. Transpressional deformation along the southern Whidbey Island fault is indicated by alongstrike variations in structural style and geometry, positive flower structure, local unconformities, out-of-plane displacements, and juxtaposition of correlative sedimentary units with different histories. The map is from a 2007 report (click here to download) on seismic design categories in Washington. Hover over a cluster of earthquakes to learn about the different types in the Pacific Northwest. The best thing you can do is to become prepared. The 1949 earthquake near Tacoma triggered a landslide near the Tacoma Narrows that caused a local tsunami. The shaking can damage or destroy buildings and other infrastructure. There are also many faults that have not been studied enough to know if they are active. endobj
We pray for people of WA and our all north Americans as well. The southern Whidbey Island fault represents a segment of a boundary between two major crustal blocks. The threat to Puget Sound from a quake along the Cascadia Subduction Zone, off the coast of Washington, Oregon and California, is well documented. This map shows different seismic design categories that correlate with amount of seismic risk. Mapping along the Snoqualmie River valley also helped answer the important question of where the Seattle fault lies east of its last mapped position near Issaquah. Consider whether earthquake insurance is right for you. This northwest-trending fault zone extends more than 65 km across Possession Sound, southern Whidbey Island, Admiralty Inlet into the eastern Strait of Juan de Fuca. The Survey is working with the Office of the Superintendent of Public Instruction (OSPI) and Reid Middleton, an engineering firm, to perform seismic safety assessments of 220 school buildings across the state. . Other faults may lie entirely underground, or could be covered by vegetation and (or) sediment. Moving inland, the Seattle Fault is capable of a magnitude 7. In the area of North Bend, the fault zone is 4 miles wide and consists of a series of parallel faults. That could spell trouble not only for its namesake island but for south and north King County and further west. If you are already planning your Christmas gifts, please buy with us on Amazon. Though it was not directly related to Johnsons work, he asked a friend working for Mobil Oil to pass along the information. The buildings in this photo were built on soft materials that liquefied during the 1964 Niigata earthquake in Japan. The Eastern Sierra fault along the east side of the Sierra Nevada mountains in California is a good example of an active normal fault. Larger crustal faults, such as the Seattle fault and southern Whidbey Island fault zone, can produce earthquakes up to magnitude 7.5. In 1985, with little concrete evidence of its existence, the pair included the possible fault on a geologic map published by the USGS. They conclude the observed features have a glaciotectonic origin and are not seimotectonic. Some people in places like SODO and Harbor Island may have to flee to higher floors in a building. By finding the age of the deformed layer, a paleoseismologist can determine the minimum age of the fault. He said he believes dramatic shifts from that quake also may be visible on the western edge of Camano Island. Photo from https://buildingfailures.files.wordpress.com/2014/02/tiltedbuilding.jpg. (1996) used seismic-reflection profiles in Puget Sound near Whidbey Island, sea-cliff exposures on Whidbey Island, and sparse borehole data to map and interpret the SWIF as a broad fault zone (6 to 11 km wide) dipping steeply to the northeast. Small talk stops. The fault, not so much. In the 1990s, scientists producedan animationthat shows inundation, and people wont have much time to run to higher ground. Most are too small to be felt or cause damage. Unlike sound, ground shaking can be amplified or attenuated (made less) depending on the type of material at the Earths surface. For earthquakes that occurred before seismographs were invented, the Mercalli Intensity scale was used to make maps of damage and determine the size and location of an earthquake. The Seattle fault is a good example of a fault that is mostly reverse. Westport currently is the only location with a vertical evacuation structure designed for a tsunami. Trenches by Sherrod and others, 2008 #7652) are less than 1 km south of KP1 and KP2 and Sherrod and others (2008 #7652) conclude that deformation in the area is due to surface-rupturing earthquakes. Scientists are not sure how far east it goes. Map Releases; Topographic (Topo) Maps; Volcanic Maps; All Maps; Multimedia Gallery. Camano Island, WA 98282, Mailing Address

Emergency planners all had a simple message: Its not IF a disaster will happen, its WHEN. During the shaking liquefaction occurred, the sand lost its strength, and the car sunk. Reverse faults are usually steep and occur in regions of compression. Then consider that the Seattle Fault is a complex of faults with various branches that run at or just below the surface. These fault strands follow the valley edges and control the location of the Snoqualmie River along some portions of the valley. ; (5) large-scale liquefaction features in upper Quaternary sediments within the fault zone; and (6) minor historical seismicity. Geologists do not yet know how often earthquakes happen on this fault. The French Onion trench exposed glaciolacustrine claystones, till, colluvial deposits, and Holocene soils. Why is Strange Sounds focusing so much on disaster preps? Faults can also occur within a tectonic plate when the plate itself is deforming. Facades crumble off buildings along Oak Harbors Pioneer Way, and some of the oldest structures in Langley and Coupeville collapse in a roaring cloud of dust. This was a problem because no two locations would agree on the size of the same earthquake. Once we got it, we were sort of shocked to see these big faults in the Puget lowlands, he said. 121 N East Camano Dr
Superior Court:(800) 254-2755
The material becomes so weak that it behaves more like a liquid than a solid. The process of breaking and moving rock releases a large amount of energy that travels through the Earth as seismic waves. For more information about earthquakes, faults, and emergency preparation, consider visiting the following sites: This map shows areas of seismic risk from high (red) to low (grayish-green). Experts have warned that UK outbreak may be around two weeks behind Italys. The friend obliged. People who look for evidence of past movement on faults are usually called paleoseismologists (from paleo-ancient and seismologist-one who studies earthquakes). In fact, new faults are found every year during our geologic mapping efforts. This map shows areas of seismic risk from high (red) to low (grayish-green). Liquefaction can be a big problem. Both of these things can cause equal or greater damage than the actual earthquake. Bookcases and china cabinets topple, trapping people beneath. These differences are related to the overall pattern of stress in the crust, what types of rocks the crust is made from, and how many faults there are.
