The Instituto Geofísico del Perú (IGP) recorded during the period 27 Apr-3 May 2020 298 volcano-tectonic earthquakes associated with magma rising, 9 explosions at regular intervals per day. The seismic station recorded on 28 April and 2 May volcano-tectonic earthquakes with magnitude M 3.4 and M 3.5 at 12 km depth beneath the southern and northeastern flank.
An explosions at the volcano generated an ash plumes, which rose approx. 8,202 ft (2,500 m) above the summit and drifted SE, S, SW and NW.
No significant changes are expected on the following days. Active lava dome is growing with diameter approx. 280 m that can lead to its collapse associated with small pyroclastic flows.
In case of rainfall, the population is recommended to stay away and avoid driving on the road that crosses the channel of this creek due to lahars (mud flows).
The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 12 km distance from the crater.
