  1. Atacama Fault
    The Atacama Fault is located on the coast of Chile and is very active.
    The fault is caused by the subduction of the Nazca plate underneath the South American plate.
    The Atacama fault is responsible for the largest known recorded earthquake, the Valdivia earthquake on May 22, 1960. Studies have placed it at around a 9.4-9.6 magnitude and caused tsunamis as tall as 25 Meters (85 Feet). An estimated 1000-7000 people died.
    More recently the fault has been active with smaller earthquakes, like the 4.9 magnitude earthquake on September 16, 2018.

    • Atacama Fault 9/21/18 Update:
      At 8:23 this morning there was a 4.3 magnitude earthquake about 50km away from Mulchen, Chile. The Atacama fault is very active and has smaller earthquakes like these frequently.

      • Atacama Fault 9/28/18 Update:
        As usual, the Atacama Fault has been hard at work, causing several earthquakes. Within the last two days alone there has been three earthquakes: a 4.3 in Chile, a 4.5 off the coast of Chile, and a 4.8 in Peru.
        Fun facts:
        -The fault is believed to have been formed in the early Jurassic period.
        -The Nazca plate is being subducted at a rate of about 9 cm (3.5 in.) per year.

        • Atacama Fault 10/5/18 Update:
          The Atacama fault was rather calm this week, within the last seven days there has only been five 4.5 or above magnitude earthquakes with the largest one being rated a 5.3 magnitude.
          More fun facts about our fault for lack of interesting earthquake content:
          -There is a major 7.0 magnitude or above earthquake every few years.
          -Since 2010 there have been several major earthquakes, here are Four of those headline making earthquakes with their year and magnitude: (2010 – 8.9, 2014 – 8.2, 2015 – 8.3, 2017 – 7.1)

  2. The Greendale fault is in the middle of New Zealand’s south island. It’s one of the main faults from Canterbury earthquake of 2010 on September 4th. The deformation is spread over a zone of 30m to 300m. The fault is about 28 km long. It is likely that Greendale fault was formed during crustal extension more than 50 to 60 million years ago. The M w 7.1 Canterbury earthquake, was the first earthquake in New Zealand to produce ground-surface fault rupture since the 1987 Edgecumbe earthquake. The Greendale Fault is an active seismic fault (a fault that is likely to become the source of another earthquake).

    • 9/20/18 (Livia B.) [Update 1]
      “In order for future rebuild to be efficient, a fault avoidance zone was defined for the Greendale fault following the Ministry for the Environmental guidelines on ‘Planning for the Development of Land on or Close to Active Faults’.”

        • The Greendale fault caused 185 deaths and damaged more than 165,000 buildings in the closest town, Christchurch. Which was shocking compared to the most fatal earthquake in 1986, killing only three people.

          • After 5 years the total monetary cost has arrived at 40 billion new zealand dollars. This converts to 26,350,460,000 USD.

  3. Alpine fault,
    It runs for about 600km up the spine of the South Island of Newzealand.
    This fault has ruptured four times in the past 900 years.
    The horizontal movement of the Alpine Fault is about 30m per 1000 years.
    The Alpine Fault is where two great tectonic plates (the Pacific and Australian) plates collide.
    The last rupture was in the 1700’s.

    • At the time our fault is active, But it has not caused any earthquakes since the 1700’s The date of the next earthquake is not known. The 300th anniversary of the last earthquake was last year which was a 8.1 quake.

    • It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate.
      It ruptured 4 times in the last 900 years.12 million years the southern alps uplifted
      by 20 km at a fast pace of erosion.
      the highest point below 4000 meters.
      There is a high possibility of the fault rupturing in the next 50 year or so.

      • The alpine fault is also sometimes called a strike-slip or transform fault. when the Pacific plate press up it makes mountains that move 7 millimeters a year but the erosion wears them down to a similar rate.
        the horizontal movement for the alpine fault is not smooth so it is rough like.

  4. Denali Fault
    The Denali Fault is located in Alaska. The Denali fault is highly active and is the fastest moving fault in interior Alaska. This fault cuts straight through Alaska’s range and the Denali State Park. The Denali fault is made by the Pacific plate sliding underneath the North American plate.
    The worst earthquake caused by the Denali fault was on 11/3/02 which caused the fault to rupture. This earth quake was found to have a magnitude of 7.9. This earthquake was found to be the worst earthquake in all of alaskan history and was so powerful it shook the lakes of Seattle.
    The Denali fault to this day is extremely active and has around 600 seismic events annually.

    • There has been no recent activity of the Denali fault and the last time it had major quake was in November of 2002. Since then the only seismic events have been very small or in the ocean. For example the only seismic events they have had are lower than a 2 and that is about every day.

      • The Denali Fault
        The Denali fault has had about 5 seismic events today along the southern coast and inland about 500 miles of Alaska. These earthquakes ranged from a magnitude of 2.5 to a magnitude of about 4.2. these earthquakes were all within one day ago. These earthquakes were located at 80km SE of Atka (4.2), 88km east of Chernabura Island (4.1), 286km SE of Kodiak (3.1), 287km SE of Kodiak (3.2), and 40km west of Anchorage (2.6).

  5. The New Madrid Seismic Zone

    The zone is sometimes called a fault line.

    Location:
    The new Madrid fault line is about 150 miles in length and goes through Illinois, Missouri, Arkansas, and west Tennessee. This is also the boundary of the Appalachian mountains.

    History:
    This zone has had 4 of the largest earthquakes in the world, which were 7.0 or larger! These quakes happened within a ten month period between December 1811 and February 1812. The first recorded earthquake happened on December 25th, 1699.

    Geology:
    This zone is right in a hotspot that formed during the breakup from the supercontinent Rodinia 750 million years ago.

    • Currently we haven’t had any recent earthquakes or any activity for the past week. The only thing significant tremors that happened were very minor earthquakes during the past month of only 1.5 intensities and averaging 6km deep.

  6. Himalayan Fault
    The Himalayan Fault boundary is a Convergent plate boundary between the Indian plate and the Eurasian plate formed 50 million years ago.
    The Himalayan Fault passes through India, Pakistan, Afghanistan, China, Bhutan, and Nepal.
    This Fault is known for being responsible of the Nepal Earthquake on April 25th, 2015 which reached a magnitude of 7.8 with aftershocks as high as 7.3. The earthquake killed nearly 9,000 people and nearly 22,000 people were injured.
    Recent activities include an earthquake that happened on September 12, 2018.
    The earthquake hit parts of Assam and West Bengal and reached 5.6 on the richter scale.

    • Himalayan Fault
      The most recent activity was the earthquake previously mentioned that hit on September 12th, 2018. The earthquake took place on Wednesday afternoon and was located 11km away from Assam’s Kokrajhar District. This quake was able to hit a 5.6 on the richter scale with tremors able to be felt all the way in parts of West Bengal.

      • Himalayan Fault
        Recently, there have been multiple earthquakes due to the Himalayan Fault. One of which occured in Kasur, Pakistan on September 23rd, 2018. This earthquake reached magnitudes of 3.8 and a depth of 10 km.
        The other recent earthquake occured in Barpeta, India. This one reached a magnitude of 4.3 and the same depth of 10 km.

        • Himalayan Fault
          This active fault boundary was back at it again with earthquakes, this time targeting Pyinmana, Burma. This quake took place on October 4th, 2018 and reached a magnitude of 4.5 with a depth of 50.5 km.

  7. The Pitaycachi fault is a fault line that starts on the South-Eastern border of Arizona and travels north into Mexico from there for about 41 kilometers.
    The fault was a sudden rupture that formed in the North American Plate on May 3rd 1887, that caused an earthquake with a scale of 7.5, commonly known as the Sonoran Earthquake which is named after the city of which the fault runs through. The Pitaycachi fault is not active anymore for it was only a rupture in a tectonic plate, The fault is now buried by sheets of late Pleistocene and Holocene piedmont alluvium.

    • The Sonora Earthquake of 1887 that had a magnitude of 7.5 on the Richter scale, 40 miles south of Douglas Arizona, with the epicenter located just below the town of Sonora Mexico, was the largest earthquake to have occurred in the southern portion of the Basin-Range province. The earthquake resulted in 51 casualties and caused building damages up to 200 kilometers away from the epicenter in towns in both the United States and in Mexico

      • The occurrence of the Sonoran earthquake caused the mountain ranges located in SouthEastern Arizona and Northern Mexico to form numerous rock falls that created sparks from crashing boulders that ignited dry brush and grass, causing forest fires to quickly form. The Sonoran earthquake caused wells to dry up which lead to a drought in the city of Sonora, but in the long run this formed temporary lakes in other areas.

  8. San Andreas fault
    The San Andreas fault is located in California and is not very active.
    The fault was created by the East Pacific Rise subducted underneath the North American plate.
    The San Andreas Fault caused the Fort Tejon earthquake on January 9, 1857. It had a magnitude of 7.9 and the U.S. Geological Survey estimated that if an earthquake of similar size happened in the same location it would damage half of the buildings in L.A., destroy the water supply and would hurt more than 50,000 people.
    The fault has been quiet and scientists think that the fault needs time to build up a critical stress level before the fault breaks or strikes again.

  9. Denali Fault
    The Denali Fault is located in the interior of Alaska and runs through the Alaska Range and the Denali National Park and Preserve. It is located on the convergent boundary between the Pacific Plate and the North American Plate.
    Tectonic processes are constantly changing the land, it is the fastest moving and most active fault zone in the interior of Alaska.
    Most recent and largest earthquake in the interior of Alaska happened on November 3, 2002.

    • On September 19, 2018 a earthquake happened 29 miles east of the Denali Park at 6:59a.m. with a magnitude of 1.0 another one happened at 9:42p.m. 33 miles east of the Denali Park with a magnitude of 2.2 Also on September 20, 2018 at 2:58a.m. an earthquake happened 20 miles east of the Denali Park with a magnitude of 1.8 Another earthquake happened that day at 2:22p.m. only 19 miles west of the Denali Park with a magnitude of 2.6

      • Since October 1, 2018 there has been approximately 8 earthquakes that have happened within 50 miles of Denali Park. This number is unusually low as we have seen numbers close to this happen within one day. Here is the largest earthquake from each day that there was activity: October 1, 2018 magnitude: 2.1 33 miles E of Denali Park, October 3, 2018 magnitude: 1.5 29 miles E of Denali Park, October 5, 2018 magnitude: 1.8 45 miles E of Denali Park another magnitude: 1.8 earth quake happened 48 miles E of Denali Park that same day, October 7, 2018 magnitude: 1.8 16 miles E of Denali Park.

  10. Kern Canyon fault
    At 150 km long, the Kern Canyon fault of the southern Sierra Nevada is the
    longest through-going fault in the batholith
    predicted that there may be an earthquake within our lifetime
    the Kern Canyon Fault runs through Kern Canyon by the Kern Canyon river in Nevada USA.

    • This year it was discovered that Kern Canyon Fault is at risk for an earthquake which could destroy the 2 Isabella dams that protect the towns of Bakersfield and Isabella Lake.

    • Nothing new has happened regarding the Kern Canyon fault this past week. Another 2 facts are the 1.25 km of the fault is exposed on the surface and the fault is made up of 90% granodiorite(an igneous rock similar to granite).

  11. The Hilina Slump Area

    Location: The Hilina Slump Area, is located on the south flank of the Kilauea Volcano on the southeast coast of the Big Island of Hawaii, is the most notable of several landslides that ring each of the Hawaiian Islands.

    History: In 1868 and 1975 this region moved several to tens of meters during major earthquakes (M7.9 and M7.2) and caused tsunamis. The tsunami generated in both 1868 and 1975 resulted in damage and death on Hawaii, and the 1975 tsunami produced minor damage in California.

    Geology: Kilauea’s entire south flank, extending out to Cape Kumukahi, is currently sliding seaward, with some parts of the central portion moving as much as 10 centimeters (4 inches) per year, pushed by the forceful injection of magma and pulled by gravity.

    • The Hilina Slump has not been active in the past week; however, we do have some interesting facts about the Hilina Slump:
      Although geologists are confident that no such failure is likely, there is evidence of massive submarine slides in the past that led to thoughts of mega-tsunamis that might happen if the southern flank of Kilauea would fail.
      The Hilina Fault is approximately 164,000 feet long, and 16,000 feet wide. It is a zone of primarily normal faults that go from East to the Southeastern flank of the Kilauea Volcano.

      • This last week, the Hilina Slump was not active. So instead I have an interesting fact for you.

        The Hilina Slump is not actually on the edge of a tectonic plate, however, it is on a hot spot that is always spewing out magma from the mantle, and then the crust is always moving. However, it moves over long periods of time, and then new islands form from the tectonic plate moving over the hot spot. There are also ancient volcanoes that have eroded and are now under the ocean water.

    • The Keweenaw Fault is a geological fault, located in Michigan. It bisects the Keweenaw Peninsula of the Upper Peninsula of Michigan. The Keweenaw Fault is a thrust fault, which means that there is a break in the Earth’s crust that pushes older rocks above younger rocks. There hasn’t been any recent activity with this fault- the continental movement that drove earthquakes along the fault hasn’t occurred in over a billion years, not making the Keweenaw Fault a threat to daily lives.

      • September 21, 2018

        In the Upper Peninsula throughout 1905 and 1906, earthquakes were felt in the Keweenaw Peninsula copper mining district. And these weren’t just faint tremors. These were earthquakes that made a 427-foot boat out in Lake Superior and swing around in a different direction. They twisted railroad tracks near Houghton into the shape of a snake. And they sent miners running out of their underground tunnels and some of the men on the next shift to refuse to go to work.

  12. The Ramapo fault.
    This fault goes through Pennsylvania and ends in New York. This is also the fourth largest fault in the world. This fault caused a 5.2 earthquake during 1998. This fault does not have any recent activity. This fault was formed 200 million years ago.

    • update:
      The Ramapo faultline was active at different times during the making and evolvement of the Appalachians. They were mainly active in the Mesozoic when they were border faults to the Newark Basin and other basins that formed when the Atlantic ocean opened, about 200 million years ago.

      • update:
        Not many people live by our fault because it is in the mountains and not many people live in mountains because of the animals or no service or even the avalanches.

        • update:
          What caused the Ramapo fault was a few earthquakes in the region, also linked to unknown faults. A earthquake in New York damaged a lot of things and caused the Ramapo fault.

  13. The San Andreas fault is located in California of somewhat along the coastline. The San Andreas fault is roughly 28 million years old. It is active and causes earth quacks. Some are small and hardly knock anything over, but some can be very violent and deadly.
    The last big earthquake was in 1857 and had a magnitude of approximately 7.9, there were a 26 seconds warning before the earthquake hit.

  14. Great Lakes tectonic zone
    The boundary that separates the two colliding bodies is the Great Lakes tectonic zone. The fault zone is highly deformed rocks. A collision began along the Great Lakes Tectonic Zone around 2,700 million years ago and it continued for tens of millions of years. Great Lakes tectonic zone is a major Precambrian crustal feature more than 1,400 km long covers eastward from Minnesota into Ontario, Canada.

    • Great Lakes tectonic zone has never been very active. The largest earthquake that was ever recorded was a 4.6 earthquake in 1975 Morris, MN. It is a late Archean crustal boundary.

      • Minor differential movements occurred locally in the Great Lakes tectonic zone, as recorded by the thinning of Cretaceous strata and their subsequent tilting and by historic earthquakes in Minnesota.

  15. The Marikina Fault Line/West Valley Fault System
    This fault contains the West Valley Fault and the East Valley Fault, two major segments and is a Dextral Strikeslip fault. This fault is made by the Phillippines Sea plate and the Sunda Plate. This Fault line is 400km long and 50km wide and spans from Calamba to Manila. No recent major activity has been recorded since 2010 when the fault made a startling shift in the area.

    • There are 3 new recordings of the Marikina Fault line in the past few days.
      The first event happened on 9-15-2018 with a rating of 4.7,
      The second event happened on 9-16-2018 with a rating of 4.6,
      The third eventhappened on 9-20-2018 with a rating of 4.9.
      No major damage done other than cracking in the road systems and few buildings.

      • No recent recorded activity in the Marikina Fault since Sept. 20th. Only fault related news are building and road repairs from the Sept. 20th 4.9 earthquake.

  16. The Marikina Fault Line/West Valley Fault System
    This fault contains the West Valley Fault and the East Valley Fault, two major segments and is a Dextral Strikeslip fault. This fault is made by the Phillippines Sea plate and the Sunda Plate. This Fault line is 400km long and 50km wide and spans from Calamba to Manila. No recent major activity has been recorded since 2010 when then fault made a startling shift in area.

  17. Great Sumatrian Fault

    Location/ the Great Sumatrian fault is located off the west coast of the island sumatra, its also located in a highly seismic area in the world.
    History/ the great sumatrian fault is 1900km long. the fault ends in the north just below the city of Banda Aceh. it is also one of the largest slip-strike faults.
    Geology/ the last earthquake was in september 30th,2009 off the coast of sumatra with a magnitude of 7.6. the great sematrain faults slip strike rate verys to 11,27mm per year.

  18. the New Madrid fault.
    located in Missouri, the history behind it is the 1811-1812 earthquake this zone made earthquakes that lasted months that lasted several months including three huge earthquakes around the magnitude of 7 and 8 they were the 3 largest earthquakes of 1811 and 1812. Earthquakes usually generate magnitude 7-8 each 500 years during the past 1,200 years.

    • update 1
      No recent activity today, something interesting about the fault system is after the 1812 earthquake was that there was at the least 2,000 after shocks that were felt on march 15, 1812. People were afraid to enter there homes scared of their houses collapsing on them.

      • update 2
        still no recent activity of anything going on in the area as it still hasn’t been active since 1812-1812 creating one of the largest earthquakes. something interesting about the New Madrid Seismic Zone is that the most active area is east of the Rocky Mountains recorded from the last forty years(2011), it has the magnitude of 1.5 its so small its barely felt.

        • update 3
          there is still no recent activity in the New Madrid fault system this week. something interesting about the new Madrid fault is that there was two similar earthquakes in 1450 AD and 900 before the 2 larger earthquakes that happened in 1811 and 1812.

  19. September 21, 2018

    Our fault doesn’t have any recent activity so I will just tell you some information about San Andreas Fault. The San Andreas Fault is the most famous fault in the world. It’s mostly famous because of the huge scary earthquake that happened in 1906. That earthquake had 3,000 casualties which is a really large amount of people. This earthquake had a magnitude of 7.9 and was rated intensity extreme. This was a very huge earthquake.

    • The San Andreas fault has had 2 earthquakes since the last time that we updated. The first earthquake happened 16 miles East of Kernville, California. It was a magnitude of 3.2 and was 8.2 km deep. The second earthquake happened right on the San Andreas fault. It was a magnitude of 2.5 and was 8.7 km deep.

      • The San Andreas fault has been quiet. There has been only 1 earthquake since our last update. It occurred about 2.5 miles SW of Tres Pinos, California. It had a magnitude of 3.8

  20. Red Sea Faults
    – the Red Sea and the Gulf of Aden have a fault system that is called a rift, the rift span is 29-31ma long taking up of almost 600,000km2 of just one region. It is also surrounded/formed by Nubia (Africa), Somalia, and Arabia. The fault of The Red Sea leads north 2,000m, leading to the Aqaba-Dead sea transform rift system.
    – The Gulf of Aden is made up of normal faults and strike-slip faults. In 1949 a deep water survey said that the Red Sea Rift had loads of hot brines it was about 140 degrees fahrenheit. New islands started to form in the Red Sea in the early 2000’s in 2007 the island of Jabal Al-Tair was found in the Red Sea, in 2011 the Red Sea errupited affecting some of the Zubair islands. From what we know no one was hurt or found dead.

    • The rift zone includes the island of Jabal al-Tair, formed by the basaltic stratovolcano of the same name, located northwest of the Bab al-Mandab passage at the mouth of the Red Sea, about halfway between Yemen and Eritrea. The volcano erupted on 30 September 2007, after 124 years of dormancy.

      • In December 23, 2011 N.A.S.A found that a volcano erupted along the Red Sea islands. they say that the lava reached a span of 90 feet NASA even caught a glimpse of what happened on that day. Fishermen also said they saw the smoke appear over the water where they were standing.

  21. On September 22, 2018 a earthquake happened 132 miles from Anchorage AK at 6:19 a.m. With a magnitude of 2,5. Another earthquake happened the day after on September 23, 2018 119 miles from Anchorage AK at 3:50 p.m. with a magnitude of 2,7. An earthquake on September 26, 2018 happened 107 miles form Willow, AK at 5:57 a.m. With a magnitude of 2,9.
    All the earthquakes happened in Denali park.

  22. Currently, for recent Activity, there was An earthquake In Tennessee that happened 13 hours
    ago. The strength of it was 1.7 on the Richter Scale and it was 6 kilometers below-the sea level. 2 Days before that, another earthquake happened which had the same magnitude but was 2 kilometers deeper.

  23. New madrid fault zone update!

    16 hours before this post there was an earth quake of a 2.1 magnitude 3.2 miles from Lilbourn, Missouri. The quake happened 14 kilometers below the surface of the town. 4 hours before that there was another earthquake that had a 1.9 magnitude quake 6 kilometers below the towns surface.
