1420 Caldera earthquake
The 1420 Caldera earthquake shook the southern portion of Atacama Desert on September 1 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.[1][2] Historical records of the tsunami exists for the Japanese harbours of Kawarago and Aiga where confused residents saw the water recede in the morning of September 1,[1] without any sign of an earthquake.[3] In Chile landslides occurred in the coast as well.[1]
