I was near the epicenter of the Chilean earthquake of 2010 (8.8),and my grandfather was in the 1960 one. The main mayority of the casualties in both earthquakes were caused by tsunamis (its really a bummer that Chile is basically a long strip of coast) we were lucky (in 2010)because the nearest big coastal population center was inside a bay, so the wave didn't hit directly. the 1960 earthquake has a very interesting history, one day before (Saturday) , there was one big earthquake(8 1-8.3, X in mercalli m) 400 km North (city of Concepción) , that cut the communications and roadways from the capital to the south of the country. On Sunday, a second earthquake of similar magnitude struck, that finished destroying the remaining buildings in the location,but nobody died on that second earthquake because everyone was outside,for obvious reasons. Finally, the big one started not on Valdivia (300 km South) but the fault line extended 1000 km reaching Valdivia and beyond, 135 people died on Japan, Valdivia itself sunk permanently 2.7 meters (8 feet) ,one chain of lakes got their exit rivers blocked, so the water level was rising rapidly and if overflowed, it would flood again the same areas affected by the earthquake, so a joint operation between military and private parties were set up to try to unblock the whole system (they succeeded), there was a case of human sacrifice, trying to calm the fury of the gods that caused such destruction, it was wild
