Destructive Earth Quakes.




hi my name is ericka im going to tell you a little bit about earthquakes.

There was an earthquake in Peru between Nazca and South American plate, The June 23 shock originated just southeast of the source of a magnitude 7.7 earthquake that occurred in 1996, and it appears to have involved rupture of part of the plate boundary segment that produced an earthquake of magnitude approximately 9.0 in 1868. The 1868 earthquake was destructive in towns that were heavily damaged in the June 23 earthquake. The 1868 earthquake produced a tsunami that killed thousands of people along the South American coast and also caused damage in Hawaii and alarm in Japan.Complex event. The initial onset consists of two events separated by about 6 seconds. It is followed by at least one larger complex event occurring about 40 seconds later.

At least 75 people were killed, including 26 killed by a tsunami. 2,687 were injured, 17,510 homes were destroyed and 35,549 homes damaged in the Arequipa-Camana-Tacna area. An additional 64 people were missing due to the tsunami in the Camana-Chala area.
