The elevated seismic activity at the volcano continues.

Earthquakes continue to be located at depths between 2 and 4 km at about 2 and 6 km distance from the crater beneath the southwestern area. Magma continues to squeeze through surrounding rocks and cracks the crust resulting in increased seismic energy.

At 05:03 local time yesterday, the strongest M 1.3 volcano-tectonic earthquake at 3 km depth was detected.

According to the Servicio Geológico Colombiano (SGC), an eruption released an ash and gas plume to about 7,8 km altitude and drifted southwest and northwest yesterday.

It is inevitable to emphasize that the activity of the volcano may fluctuate and suddenly decrease to lower levels. So far, under current conditions, the alert level for the volcano remains like this for the coming weeks.
