Eruptions du volcan Huaynaputina : 1600, 7750 BC ± 200 years Derniers séismes proches:
Prior to the 1600 eruption, it had not even been known as a volcano and was described as a "low ridge in the center of a Sierra". Introduction:Huaynaputina volcano does not form a prominent topographic elevation. It is located inside a 2.5 km wide older caldera that was deepened by glacial erosion. The volcano consists of 3 overlapping cinder cones containing up to 100 m deep craters. These cones formed during the 1600 AD eruption. The flanks of the older edifice are deeply covered by ash deposits from the same eruption.1600 AD Plinian eruption of Huaynaputina volcano
The eruption of Huaynaputina volcano in 1600 AD was the largest historically recorded eruption in South America and one of the largest in the world during the past 2000 years. It erupted up to 30 cu km of tephra (or ca. 12 km3 of magma) (VEI 6) and is comparable to the Plinian eruption of Krakatau in 1883. The pumice and ash layer from the eruption covers an area of 360,000 km2. This powerful eruption was fed by fissures and produced pyroclastic flows and surges that traveled 13 km to the east and SE. Hot mud flows (lahars) reached the Pacific Ocean, 120 km away. ...plus |
