Most studies have placed it at 9.4–9.6 on the moment magnitude scale, [1] while some studies have placed the magnitude lower than 9.4, [6][7] making it the most powerful earthquake ever recorded. It occurred in the afternoon (19:11:14 GMT, 15:11:14 local time), and lasted 10 minutes.

2025年2月6日 · A sudden breaking in the rocks along a roughly 560–620-mile (900–1,000-km) stretch of the Nazca Plate caused the earthquake, which has been generally agreed to have had a magnitude of 9.5—the largest earthquake recorded in the 20th century.

The largest earthquake instrumentally recorded had a magnitude of 9.5 and occurred in southern Chile on May 22, 1960. It produced a tsunami that killed people around the Pacific Basin - in Hawaii, California, Japan, the Philippines and other locations.

On May 22, 1960, the most powerful earthquake in recorded history— magnitude 9.5—struck southern Chile. Estimates were the rupture zone stretched anywhere from 500 kilometers (311 miles) to almost 1,000 kilometers (621 miles) along the country’s coast.

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 …

The magnitude 9.5 Chilean earthquake in 1960 was the largest earthquake ever instrumentally recorded. The series of earthquakes that followed ravaged southern Chile and produced one of the longest ruptures ever reported.

This is the largest earthquake of the 20th Century. The rupture zone is estimated to be about 1000 km long, from Lebu to Puerto Aisen. Note that the tsunami deaths from outside Chile are included in the 1,655 total. This is still considerably fewer …
