Deepest Earthquake Ever Recorded
Earthquakes are devastating natural occurrences. Earthquakes happen when the plates underneath the Earth move around. It is a natural occurring phenomenon that has happened ever since the Earth was created. They can be very devastating. The first ever recorded earthquake was on 1769 during an exploration expedition at Gaspar de Portola near Los Angeles. There were earlier records of massive earthquakes but were not made official by any means.
The largest recorded earthquake happened on May 22, 1960 in Chile with a magnitude of 9.2. Some may think thatthey only happen on Earth but quakes also happen in other parts of the Solar system. Moonquakes or “earthquakes” on the moon happen as well but are very rare and have smaller magnitudes. There are more than 500,000 detectable earthquakes that happen every year and only 100,000 of those can be felt and 100 of which are destructive.
Most of them occur on depths at 50 miles below the Earth’s surface but there are also earthquakes that happen as deep as the Earth’s sublayers. These deep ones can be very devastating if one or more plates are affected. Find out which is the deepest earthquake ever recorded and how it happened by reading below.
The Deepest Earthquake Ever Recorded
These disastrous situations happen when tectonic plates shift. These plates are found deep under the surface of the Earth and when they move, the surface of the Earth also moves with it. The deepest earthquake ever recorded happened just recently. A massive 8.3 magnitude earthquake happened at the Kamchatka Peninsula in Russia on May 24, 2013. It was recorded at a record depth of 378 miles underneath the surface. The previous record was held during a Bolivian earthquake but scientists believe that the recent one in Russia was the deepest ever recorded.
The earthquake itself was very deep that it also shook other plates and affected different parts of the world though these regions have not felt or slightly felt it. The massive earthquake happened at the Sea of Okhotsk which lies above a subduction zone where the North American Plate dives underneath. The northwest Pacific plate is one of the oldest and coldest ocean crust subducting on Earth therefore such massive earthquake heavily affected the plate that subducted it. It also reached the other side of Russia wherein citizens of Moscow felt the Earth moved at 4,000 miles away from the epicenter.
Other Facts About Earthquakes
Each year Southern California has about 10,000 earthquakes. They are so small or weak in terms of magnitude but they happen often. Most of the time they happen at a magnitude of 3.0. One of the most devastating earthquakes happened on 1556 where people living on caves were covered and killed almost 800,000 people. Another happened on 1976 still in China that killed more than 250,000 people. During the record breaking Chilean earthquake, seismic waves traveled all around the world that it shook the entire planet which scientists termed as the free oscillation of the Earth.
