The Instituto Geofísico del Perú (IGP) noted that vulcanian-type explosions at regular intervals of 30 per day occurred from the summit crater during 27 Sept-3 Oct.
Eruption columns rose to an estimated altitude of 24,000 ft (7,300 m) and drifted most often SE direction.
The seismic station detected approx. 989 volcano-tectonic earthquakes with average magnitude M 2.0-M 3.5 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.
