December 26, 2004, Indian Ocean
The magnitude was 9.1 points. The earthquake occurred most lethal in modern history, the tsunami that killed nearly 300 000 people. The horrific earthquake changed the Earth’s rotation rate, because of what knocks have become shorter in 2.68 microseconds.
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.
