On 11 March SERNAGEOMIN raised the Alert Level for the Antillanca Volcanic Complex to Yellow because of increased seismicity near Casablanca stratovolcano. Volcano-tectonic (VT) earthquakes began to be recorded in August 2019 and were located about 6.3 km NE of the stratovolcano. During 31 January-1 February a total of 131 VT events were located to the W and NW; the two largest events were M 3.1 and 3.2. A swarm of 73 VT events were detected on 9 March with epicenters located 2.4 km NNW and a maximum local magnitude of 1.8.

Photo Gallery

Casablanca volcano, whose summit is visible at the upper right, is the highest peak of the Antillanca volcano group. Raihuen crater (lower left) lies at the base of Casablanca. The Antillanca Group is a cluster of late-Pleistocene to Holocene scoria cones, maars, and small stratovolcanoes covering an area of 380 sq km SE of Lago Puyehue and NE of Lago Rupanco. Older late-Pleistocene stratovolcanoes have been extensively dissected by glaciers, but numerous small Holocene volcanic centers are present.
