The INGEMMET volcano observatory reported that satellite observations confirmed a fifth lava dome.
It appears as a hill-shaped and circular mass of viscous lava rising into it within the summit crater. The dome is located about 6 km north of the crater with approx. volume of 25,000 m2.
Volcanologists dubbed it the „Pichqa” meaning ‚five‘ in Quechua native language.
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 21 per day occurred from the summit crater during 16-22 May.
Eruption columns rose to an estimated altitude of 24,000 ft-25,000 ft (7,300 m-7,600 m) and drifted most often S-SE direction.
The seismic station detected approx. 356 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.
