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.
