Chile’s Calbuco volcano has erupted twice in the last 24 hours, according to the country’s National Service of Geology and Mining (SERNAGEOMIN).
SERNAGEOMIN says the pulsations from the eruption are gradually losing power, but the red alert threat level is still in effect.
According to SERNAGEOMIN (rough English translation):
Superficially an eruptive column was developed with a height greater than 15 kilometers, which was dispersed north, northeast and east. This event was accompanied by a continuous emission of fragments of incandescent material, which did not exceed 5 kilometers around the [volcano]. The accumulation of pyroclastic material (ash and pumice) has been concentrated to the north and northeast of the volcano, whose thicknesses vary from tens of centimeters in the Lakes Region until a few millimeters in the regions of La Araucanía and Los Ríos.
Approximately 4,500 people have been evacuated from Calbuco as a result of a 20-kilometer evacuation zone.
The eruption process started on April 22 at 6:05 p.m. It is the volcano’s first eruption since 1972 and first major eruption since 1962.
