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.
The earthquakes are caused by slip along the thrust fault that forms the contact between the two plates. These interplate earthquakes are the planet's most powerful, with moment magnitudes (M w) that can exceed 9.0. [1] [2] Since 1900, all earthquakes of magnitude 9.0 or greater have been megathrust earthquakes. [3]
On Dec. 26, 2004, a 9.2-magnitude earthquake shook Southeast Asia, triggering the worst tsunami in recorded history. According to United Nations estimates, more than 220,000 people were killed ...

In 2011, more than 18,000 people lost their lives amid a magnitude-9.0 earthquake and tsunami in Tohoku, Japan, The New Yorker noted. That catastrophe wound up costing approximately $220 billion.
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". [3]
Lasting four minutes and thirty-eight seconds, the magnitude 9.2–9.3 megathrust earthquake remains the most powerful earthquake ever recorded in North America, [2] [4] and the second most powerful earthquake ever recorded in the world since modern seismography began in 1900. [5]
The first was a magnitude 5.9 that was reported just before 11 a.m. ET approximately 22 miles south of Bartolomé Masó, ... Earthquakes off Cuba’s coast damage homes, ...
