The explosive eruption of the volcano continues at moderate levels and its activity has remained essentially unchanged.
The Instituto Geofísico del Perú (IGP) noted that vulcanian-type explosions at regular intervals of 37 per day occurred from the summit crater during 18-24 April.
Eruption columns rose to an estimated altitude of 21,000 ft-26,000 ft (6,400 m-7,900 m) and drifted most often S-SE direction.
The seismic station detected approx. 140 volcano-tectonic earthquakes accompanied by rising magma flux inside the volcano’s conduits.
Lahars (mud flows) could also occur if heavy rainfalls remobilise the fresh ash deposits.
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.
