Has there ever been an 8.5 earthquake?
Mw 9.5 earthquake

On May 22, 1960 a great Mw 9.5 earthquake, the largest earthquake ever instrumentally recorded, occurred off the coast of southern Chile. This earthquake generated a tsunami that was destructive not only along the coast of Chile, but also across the Pacific in Hawaii, Japan, and the Philippines.Sendai, Japan 11 March 2011 (magnitude 9.0)1 – Valdivia, Chile, 1960

The biggest earthquake ever recorded occurred in 1960 near the city of Valdivia, Chile. With a magnitude of 9.5, it was one of the deadliest earthquakes in history, killing an estimated 5,700.

What was the largest earthquake in Europe : On December 28, 1908, at approximately 5:20am, Europe's most powerful earthquake shook southern Italy. Centered in the Messina Strait, which separates Sicily from Calabria, the quake's magnitude equaled a 7.5 by today's Richter scale.

How strong is a 9.5 earthquake

For comparison, the biggest earthquake, a magnitude 9.5 earthquake off the coast of Chile, registers as 1 x 10^19 joules, or 10 exajoules.

How long did the 9.5 earthquake last : It occurred in the afternoon (19:11 GMT, 15:11 local time), and lasted for approximately 10 minutes.

Approximately 1,655 killed, 3,000 injured, 2,000,000 homeless, and $550 million damage in southern Chile; tsunami caused 61 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damage in Japan; 32 dead and missing in the Philippines; and $500,000 damage to the west coast of the United States.

Simulations of the recurrences of M9 earth- quakes based on the lengths of trenches and convergence rates suggest that the global occur- rence of M9 earthquakes is 1–3 per century, and the 5 that occurred in the past 100 yr may be higher than long-term averages.

How long does a 9.0 earthquake last for

5–7 minutes

It is capable of producing 9.0+ magnitude earthquakes and tsunamis that could reach 30 m (98 ft). The Oregon Department of Emergency Management estimates shaking would last 5–7 minutes along the coast, with strength and intensity decreasing further from the epicenter.If you are able, seek shelter under a sturdy table or desk. Stay away from outer walls, windows, fireplaces, and hanging objects. If you are unable to move from a bed or chair, protect yourself from falling objects by covering up with blankets and pillows.Earthquakes in Germany are relatively weak but occur several times a year, some of them in coal mining areas where blasting sets them off.

Researchers at the EU-funded SHARE project have produced a map displaying which parts of Europe are most at risk from an earthquake, and it shows that Italy, the Balkans, Greece, Bulgaria, Romania and Turkey are among the most exposed regions of the continent.

What is a 10.0 earthquake 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.

How bad is 10.0 earthquake : A magnitude 9.0 earthquake on Richter scale is equivalent to release of energy by 25,000 nuclear bombs. So a 10.0 magnitude earthquake will be analogous to dropping over 4,00,000 nuclear bombs at a time. This is enough to destroy anything and everything on earth if it is a point source on the surface.

How long does a 9.0 earthquake shake

A magnitude 9.0 earthquake can last for five minutes or longer, and the amount of energy released is about 1,000 times greater than that of a 7.0 . According to the U.S. Geological Survey, the most powerful quakes could leave few if any masonry buildings standing, destroy bridges and toss objects into the air.

1,655 killed

Approximately 1,655 killed, 3,000 injured, 2,000,000 homeless, and $550 million damage in southern Chile; tsunami caused 61 deaths, $75 million damage in Hawaii; 138 deaths and $50 million damage in Japan; 32 dead and missing in the Philippines; and $500,000 damage to the west coast of the United States.Approximately 1,655 people were killed, 3,000 injured, and about 2-million people were left homeless. No, there has never been a 9.9 earthquake recorded in modern history. The largest earthquake ever recorded was the Great Chilean Earthquake of 1960, which had a magnitude of 9.5 on the moment magnitude scale.

Can a 9.5 earthquake happen : The Valdivia earthquake, named after the town closest to its epicenter, was roughly a magnitude 9.5, the largest ever recorded before or since.
