Who invented the Richter scale and why?
The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.
Which ocean has the most earthquakes?
Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the ‘Ring of Fire’; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.
In which year Richter scale is invented?
The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.
What is an earthquake expert called?
Seismologists study earthquakes by looking at the damage that was caused and by using seismometers. A seismometer is an instrument that records the shaking of the Earth’s surface caused by seismic waves.

Which country has most earthquakes?
For which country do we locate the most earthquakes? Japan. The whole country is in a very active seismic area, and they have the densest seismic network in the world, so they are able to record many earthquakes.

Is a 10.0 earthquake possible?
No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. … The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles long…a “megaquake” in its own right.
Is a 6.2 earthquake big?
Getty/AFP A strong earthquake is one that registers between 6 and 6.0 on the Richter scale. There are about 100 of these around the world every year and they usually cause some damage. In populated areas, the damage may be severe.
What would a magnitude 10 earthquake be like?
It’s doubtful that there are any fault lines on Earth big enough to release a magnitude 10 earthquake, but if one happened, you could expect the ground to shake just as hard as a magnitude 9, but for a lot longer – perhaps as much as 30 minutes. …
What are the two types of earthquake?
There are two types of earthquakes: tectonic and volcanic earthquakes. Tectonic earthquakes are produced by sudden movement along faults and plate boundaries.

Who named earthquakes?
Robert Mallet realised that most earthquake damage is due to moving waves caused by a sudden land movement, named seismic waves.
Has there ever been a 9 earthquake?
The world’s largest earthquake with an instrumentally documented magnitude occurred on May 22, 1960 near Valdivia, in southern Chile. It was assigned a magnitude of 9.5 by the United States Geological Survey. It is referred to as the « Great Chilean Earthquake » and the « 1960 Valdivia Earthquake. »
What was the longest lasting earthquake?
A devastating earthquake in Indonesia in 1861 was the crescendo of a 32-year-long clash between the tectonic plates below the island. It is the longest such ‘slow slip event’ ever recorded, and it left its mark in the bodies of the long-lived corals that inhabit the seas above.
