The 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) occurred on 22 May 1960.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.
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.
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. [3] [7] Its epicenter was near Cañete, Bío Bío Region, Chile, and its magnitude was 8.1 [1] or 8.3 [2] M W and 7.3 [3] or 7.5 [4] M S. This earthquake, which lasted 35 seconds ...
