The 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) on 22 May 1960 was the most powerful earthquake ever recorded. 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.
Only two of those generated damage, the 1960 Chile earthquake and the 1964 Alaska earthquake, which generated waves of almost 4 feet at the San Francisco Presidio, the authors reported ...
22 May – occurs the 1960 Valdivia earthquake With a magnitude of 9.5 MW, it is the largest recorded in the history of mankind Its epicenter was the city of Valdivia and mainly affected the area between Talca and Chiloé Archipelago The earthquake was felt in different parts of the planet and produced both a tidal wave —which affected various locations throughout the Pacific Ocean such as ...
A tsunami hitting a coastline. This article lists notable tsunamis, which are sorted by the date and location that they occurred.. Because of seismic and volcanic activity associated with tectonic plate boundaries along the Pacific Ring of Fire, tsunamis occur most frequently in the Pacific Ocean, [1] but are a worldwide natural phenomenon.

The 1960 Concepción earthquakes were a succession of three destructive earthquakes that happened between 21 and 22 May 1960. They formed part of the foreshock sequence for the 1960 Valdivia earthquake, the largest recorded earthquake in history. [6] The first was on May 21 at 06:02 UTC-4.
On May 23, 1960, a tsunami originating from the 1960 Valdivia earthquake in Chile (the most powerful earthquake ever recorded) killed 61 people in Hilo. After the February 27, 2010 Chile earthquake , the effectiveness of the Pacific Tsunami Warning Center (PTWC) was shown, as no one was injured on Hilo Bay after the (PTWC) sirens sounded and ...
Chile lies in a region which is adjacent to the fast-moving Nazca plate, and has high tectonic activity.The records for earlier centuries are apparently incomplete. Of the world's 46 known earthquakes with M ≥ 8.5 since the year 1500, one-third occurred in Chile [citation needed] and are shown in the map to the side.
