The highest Richter scale value for an historical earthquake was the Great Chilean Earthquake (Valdivia Earthquake) of 1960, which occurred on May 22, 1960.
Its moment magnitude was estimated at 9.5 on the Richter scale (9.4 to 9.6).
The "worst" earthquake in modern history occurred on May 22, 1960, in Valdivia, Chile. It measured 9.5 on the Richter scale, the largest recorded earthquake in history.
the earthquake of '64. It was 9.2 on the Richter scale.
The biggest ever earthquake occured in Egypt on 1201 it mesured 9.6 on the Richter scale and killed an estimated one million people.
The largest earthquake in the world was the 1960 Voldivic earthquake. It was the most powerful earthquake ever recorded. It rated 9.5 on the magnitude scale. It occurred in the afternoon.
No. It is neither the most powerful nor most destructive (in terms of number of deaths). The most powerful earthquake ever was the Valdivian / Great Chilean Earthquake of 1960 (9.5 on Richter scale) and the most destructive was the Shaanxi, China earthquake of 1556 which supposedly killed 850 thousand people. Today's earthquake in comparison was 8.9 on the Richter scale and so far 300 people have been confirmed dead and 500 more missing.
Probably the huge earthquake Japan had recently. I heard it was an 8.9 on the Richter scale.
5 largest in japan
The largest in recorded history was a 9.5 earthquake in Chile.
it is the third largest in the world.
The largest recorded earthquake in the world was a magnitude 9.5 (Mw) in Chile on May 22, 1960.
The weakest earthquake ever recorded was in 1962 and it was approximately 0.001643 on the Richter scale. Hope that answers your question Peter I. Staker, National Geographic Seismologist
firstly it depends on the Richter scale and the different types of plates that are all around the world for example: in japan, there was an earthquake that measure-rd 9.0 in the Richter scale. but in Iran it measured a 6.3 magnitude in the Richter scale. so what i meant by that is that each part of the world has its own plate.
