September 1, 1923, Tokyo-Yokohama, Japan
This earthquake of magnitude 8.3 points still called the Great Kanto earthquake, as the Japanese Kanto province most affected by the strike element. For two days there was 356 aftershocks, and the height of the tsunami in Sagami Bay has reached 12 meters. The death toll in the disaster is estimated at 142,800 people.
Valdivia was a 9.5, not 9.6.
Also: Alaska, 1964: 9.2 and Kamchatka, Russia, 1952: 9.0.
Damn Earth.
BTW, the latest earthquake had a magnitude of 9 not 9.1.
