How was the Richter scale named?
The Richter scale – also called the Richter magnitude scale or Richter’s magnitude scale – is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the “magnitude scale”.
Who is Mr Charles Richter?
Richter, in full Charles Francis Richter, (born April 26, 1900, near Hamilton, Ohio, U.S.—died September 30, 1985, Pasadena, California), American physicist and seismologist who developed the Richter scale for measuring earthquake magnitude.
What is the largest earthquake ever recorded?

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.
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.
What would a magnitude 12 earthquake be like?
A magnitude 12 earthquake would require a fault larger than the earth itself . Volcanic arcs and oceanic trenches partly encircling the Pacific Basin form the so-called Ring of Fire, a zone of frequent earthquakes and volcanic eruptions. The trenches are shown in blue-green.
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 is the highest Richter scale?
In theory, the Richter scale has no upper limit , but, in practice, no earthquake has ever been registered on the scale above magnitude 8.6. (That was the Richter magnitude for the Chile earthquake of 1960. The moment magnitude for this event was measured at 9.5.).
What does a 4.0 earthquake feel like?
4.0 – Feels like a large truck passing by or even the shaking caused by an explosion nearby . 5.0 – Unmistakable as an earthquake, this can rattle dishes, break windows, and rock cars. Poorly constructed buildings are at high risk of structural damage.
In which year Richter scale is invented?
The Richter scale was developed in 1935 by American seismologist Charles Richter (1891-1989) as a way of quantifying the magnitude, or strength, of earthquakes.
What is a seismologist?
Research seismologists study the internal structure of the Earth and try to determine factors that contribute to or foretell an earthquake . They publish their findings in scientific journals or present them at academic forums—or do both.
Which type of measurement gives the most reliable estimate of earthquake size?
Because of the limitations of all three magnitude scales (ML, Mb, and Ms), a new, more uniformly applicable extension of the magnitude scale, known as moment magnitude , or Mw, was developed. In particular, for very large earthquakes, moment magnitude gives the most reliable estimate of earthquake size.
What is the Richter scale and who is it named after?
The Richter scale was named after Charles F. Richter , an American seismologist, who in 1935 developed the system for measuring the strength of earthquakes.
