Previous and later earthquakes[edit]
There is evidence that a similar earthquake and landslide occurred in 1575 in Valdivia.[35] This earthquake was of similar strength and also caused a Riñihuazo. According to the chronicle of Mariño de Lobera, corregidor of Valdivia in 1575, a landslide blocked the outflow of the lagoon of Renigua. Several months later in April, it caused a flood.[36] He said that the Spanish settlers had evacuated and waited on high ground until after the dam burst, but many aboriginals died in the flood waters.[36]
On 27 February 2010 at 03:34 local time an 8.8 magnitude earthquake occurred just to the north (off the coast of the Maule region of Chile, between Concepción and Santiago).[37] This quake was reported to be centered approximately 35 kilometres (22 mi) deep and several miles off shore. This 2010 Chile earthquake may be related or consequential to the 1960 tremor.[38]
