In the last 24 hours, Cenapred has reported to Popocatépetl 37 exhalations, unobservable visually due to high cloudiness.

Two explosions took place on June 3rd, at 9:17 am and 9:47 am, accompanied respectively by ash plumes at about 3,500 and 2,800 meters above the crater. The first ejected materials at 2 km on the southern flank of the volcano.

The seismicity is marked by 194 minutes of trémor.

The volcanic alert remains at Amarillo Fase 2.

At Etna, a small explosive and effusive activity continues on June 3 at the open mouth on May 30 at the southeastern base of the new southeastern crater.

The casting at the north base of the NSEC is no longer powered and is being cooled.

The average amplitude of the volcanic tremor continues to show a downward trend.
