1420 Caldera earthquake
The 1420 Caldera earthquake shook the southern portion of Atacama Desert on August 30, 1420 and caused tsunamis in Chile as well as Hawaii and the towns of Japan. The earthquake is thought to have had a size of 8.8-9.4 Mw. Historical records of the tsunami exist for the Japanese harbours of Kawarago and Aiga where confused residents saw the water recede in the morning of September 1, without any sign of an earthquake. In Chile, rockfalls occurred along the coast as well, producing blocks of up to 40 tons that are now found inland. This is also consistent with the identification of a possible tsunami deposit in Mejillones Bay that has been dated to the range 1409 to 1449. Deposits found by coring of recent sediments in wetland near Tongoy Bay have also been linked to the 1420 tsunami.
