The earthquake that struck near Valdivia, Chile, in 1960 was the most powerful temblor in recorded history. The quake left about 2 million people homeless. On May 22, 1960, the most powerful earthquake in recorded history—magnitude 9.5—struck southern Chile.
What causes Chile earthquakes?
Chile is a hotspot for earthquakes because the Nazca plate, a tectonic plate which moves eastwards with a rate of 6.6 cm per year, collides with the South American plate off the Chilean coast. For example, the plates shifted by more than 30 meters in the 1960 earthquake.
What caused the tsunami in Chile 1960?
A Pacific-wide tsunami was triggered by the earthquake, which had a surface-wave magnitude of 8.6, an epicenter of 39.5° S, 74.5° W, and a focal depth of 33 km. The number of fatalities associated with both the tsunami and the earthquake has been estimated to be between 490 to 2,290.
How long did it take for the Tohoku tsunami to arrive?
On March 11, 2011, a magnitude (Mw) 9.1 earthquake struck off the northeast coast of Honshu on the Japan Trench. A tsunami that was generated by the earthquake arrived at the coast within 30 minutes, overtopping seawalls and disabling three nuclear reactors within days.
How fast was the 1960 Chile tsunami?
several hundred km/h
The main tsunami crossed the Pacific Ocean at a speed of several hundred km/h and on May 23, 1960 (about 15 hours after the earthquake) a train of 35-foot waves reached the Hawaiian Islands and crashed into Hilo Bay.
How many people died from the 1960 Chilean tsunami?
61 people dead
Play it safe, even if warnings seem ambiguous or you think the danger has passed. In Hilo, Hawaii, the 1960 Chilean tsunami left 61 people dead and 282 seriously injured.
How much money did the Tohoku earthquake cost?
The costs resulting from the earthquake and tsunami in Japan alone were estimated at $220 billion USD. The damage makes the 2011 Great East Japan earthquake and tsunami the most expensive natural disaster in history. Although the majority of the tsunami’s impact was in Japan, the event was truly global.
What was the cause of the earthquake in Chile in 1960?
The Nazca Plate is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The Chile earthquake of 1960 was caused by the release of mechanical stress due to the subduction of the Nazca Plate under the South American Plate along the Chile-Peru Trench, which has been the cause of many other earthquakes too.
Where was the earthquake on this day in 1960?
On This Day: Great Alaska Earthquake and Tsunami. On the evening of March 28, 1964, without warning, the largest recorded earthquake in U.S. history struck Alaska’s Prince William Sound. On This Day: 1960 Chilean Earthquake and Tsunami. In 1960, the largest earthquake ever instrumentally recorded occurred in southern Chile.
Where was the epicenter of the 1960 Valdivia earthquake?
#4 The epicenter of the 1960 Valdivia earthquake was near Lumaco. The focus of the earthquake was relatively shallow at 33 km, as other earthquakes in the region are known to reach depths of 70 km. Focus is the point where an earthquake originates while epicenter is the point on Earth’s surface directly above the focus.
Where was the epicenter of the Chilean earthquake?
A large and powerful set of aftershocks can be expected from this earthquake.The earthquake, was centered some 65 miles west-southwest of Talca, Chile, about 21.7 miles below the ocean’s surface, “relatively shallow for a subduction quake,” said Lin.
