Scientists estimate that this earthquake shifted Earth's axis and shortened the length of a day by 1.26 microseconds. A few minutes later, after this 8.3 magnitude earthquake was over, 125 people were dead and a third of the buildings in town lay in ruins. Since 1900, numerous magnitude 8 or larger earthquakes have occurred on this subduction zone interface that were followed by devastating tsunamis, including the 1960 M9.5 earthquake in southern Chile, the largest instrumentally recorded earthquake in the world. The first Concepción earthquake struck at 06:02 on 21st May 1960. Keep up to date with more stories like this by liking our Facebook page!

Suddenly, at two minutes after 6 am local time, the Earth under the coastal town of Concepcion began to shake violently. Chile has had: (M1.5 or greater) 3 earthquakes in the past 24 hours 11 earthquakes in the past 7 days; 57 earthquakes in the past 30 days; 751 earthquakes in the past 365 days 58,622 homes were destroyed. It also puts a huge amount of mechanical strain on the western edge of South America. Earthquakes in Chile. It is subducting under (that is, being forced under) the South American plate. Only aftershocks above magnitude 6.5 will be listed to prevent cluttering. It was actually a series of strong earthquakes that affected Chile between May 21, 1960 and June 6, 1960. 1960 Valdivia earthquake damage, USGS. The shock of this upward thrust also pushed the water above the plate boundary upward, creating a wave that moved outward in all directions. It was located in Valdivia in May,22,1960. Source: Press Association. Universal Studios. Buildings damaged by earthquake and fire, Castro, Chiloé Island, after the Chile earthquake of May 22, 1960. Though the oblique angle by which the waves approached the Pacific coast of the United States mitigated their force, Crescent City, California, saw waves of up to 5.6 feet (1.7 metres), and boats and docks in Los Angeles, San Diego, and Long Beach were damaged. The magnitude of the 1960 earthquake in Chile is roughly 1.3 times that of Haiti's 2010 earthquake. In fact, during the past 150 years or so, Chile has had more giant quakes with magnitudes of 8 and larger than any other region in to world. Index maps.a, Plate-tectonic setting of south-central Chile. 1960-06-06 05:55:48 UTC 7.8 magnitude, 15 km depth Puerto Chacabuco, Aisén, Chile 7.8 magnitude earthquake 1960-06-06 05:55:48 UTC at 05:55 June 06, 1960 UTC The Japan earthquake of 2011 had a magnitude of 9.0; it spawned a tsunami that killed an estimated 19,300 people in Japan and knocked out the electrical power to Japan’s Fukushima Daiichi nuclear power plant, creating the world’s second most serious nuclear emergency. In the Philippines, tsunami waves left 32 dead or missing. International cooperation in this area began following the 1960 Chile earthquake which, at magnitude 9.5, is the largest ever recorded. Valdivia earthquake Various studies have placed it at 9.4–9.6 on the moment magnitude scale. Get a Britannica Premium subscription and gain access to exclusive content. Newsreel describing the Chile earthquake of 1960. Originating off the coast of southern Chile on May 22, 1960, the temblor caused substantial damage and loss of life both in that country and—as a result of the tsunamis that it generated—in distant Pacific coastal areas. Exactly 16 Minutes after the severe aftershock, the Earth literally opened up. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Scientists estimate that this earthquake shifted Earth's axis and shortened the length of a day by 1.26 microseconds. Debris from buildings damaged by a nearly 35-foot (11-metre) tsunami, Hilo, Hawaii island, Hawaii. According to modern calculations, this Great Chile Earthquake of May 22, 1960 had a moment magnitude of 9.5, which makes it the largest earthquake ever recorded, bigger even than the Great Alaska Earthquake of 1964, which registered 9.2 on the world record scale. Chile was hit by 17 earthquakes with a magnitude of 4 and more in 1960. From a plate tectonics point of view, South America is relatively stable, but the Nazca Plate is pushing eastward at a rate of approximately 2 inches per year.

Chile has had a lot of earthquakes. Newsreel describing the Chile earthquake of 1960. The force of the sudden movement along a roughly 560–620-mile (900–1,000-km) stretch of the Nazca plate pushed part of the leading edge of the South American plate upward. The waves caused millions of dollars of damage at Hilo Bay on the main island of Hawaii, where they also killed 61 people. The reason why the earthquake accrued is the Nazca Plate has been colliding and subducting underneath the South American plate for thousands of years. The enormity of the seafloor shifts that caused the tsunamis was such that the waves that arrived nearly 15 hours later in the Hawaiian Islands—6,200 miles (10,000 km) away—still crested at nearly 35 feet (11 metres) at landfall in some places. About 3,000 people were injured. The tsunami, caused by this monster quake, wreaked havoc all across the Pacific, from Hawaii to Japan and Alaska. Further inland, giant landslides had buried villages and towns. It hit off the coast of Chile and was a 9.5 magnitude earthquake. During the lifetime of this blog alone, a magnitude 8.2 struck in April of last year and a magnitude 8.8 caused major destruction early in 2010.  |, May 22, 2015  From Chile the tsunami radiated outward, killing 61 people in Hawaii and 122 in Japan. Chile is not only the longest country on Earth, it is also one of the most earthquake prone nations. In fact, the most powerful earthquake ever recorded was a 9.5 in 1960 in close proximity to the epicenter of Saturday’s quake. On May 22, 1960, the stress built up by years of increasing compressional force between the rocks of one plate and another was released by fracturing rocks. Categories:   b, Documented effects of the 1960 earthquake and its historical predecessors. Various studies have placed it at 9.4–9.6 on the moment magnitude scale. Destruction after the largest earthquake of the century in Valdivia on May 22, 1960 Time line of Earthquakes in Chile. Several coastal towns were inundated by a 25-metre (80-foot) tsunami. Two days later the Cordón Caulle volcano in Chile’s Lake District erupted after nearly 40 years of inactivity, an event thought by some seismologists to be linked to the quake.

For several days after the earthquake, the whole Earth rang like a bell. Earthquakes are caused by movements within the Earth's crust and uppermost mantle.They range from events too weak to be detectable except by sensitive instrumentation, to sudden and violent events lasting many minutes which have caused some of the greatest disasters in human history.
