Yate

Geography & Climate

Yate is located in Chile, within the Southern Andean Volcanic Arc of the broader South America Volcanic Regions. Situated at 41.76° S, 72.40° W in the Southern Hemisphere, the volcano lies within a temperate climate zone. At 2,187 meters above sea level, Yate rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.

Geological Context

Yate sits in a subduction zone, where one tectonic plate dives beneath another, creating intense heat and pressure that generates magma. Subduction zones are responsible for many of the world's most explosive volcanoes and deadliest eruptions. For communities in Chile near Yate, this tectonic setting means the volcano is capable of producing powerful explosive eruptions, pyroclastic flows, and lahars that can threaten populated areas within tens of kilometers of the summit. The dominant rock type is andesite / basaltic andesite, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.

Eruption History Summary

Yate has 1 recorded eruption in the geological database, spanning from 1090 CE to 1090 CE.

GVP Reference Summary

Yate volcano is a late Pleistocene, glacially dissected basaltic andesite stratovolcano with Holocene flank vents. One of these flank vents is labeled Volcán Yate on the Volcán Hornopirén 1:50,000 quadrangle map. This isolated feature, NNE of Volcán Hornopirén and S of the Relancaví strait, shows evidence of Holocene eruptions. Elongated, it contains six eruptive centers localized along a NW-trending fissure ~7.5 km long. The most recent activity originated from basaltic andesite pyroclastic cones on the NW and W flanks. No reported eruptions are known, although the fresh morphology of its flank cones suggests recent activity (González-Ferrán, 1995). A non-eruptive landslide in 1965 produced a debris flow that reached Lake Cabrera, causing a tsunami that destroyed a settlement and caused 27 fatalities.
