Worldwide Volcano News and Updates

Activity continues with little changes. Video data showed that the lava dome is still active and produces incandescence and hot avalanches on the western and eastern flanks. Strong and moderate gas-steam activity accompany this process. Satellite data showed a thermal anomaly over the volcano. (KVERT)

The lava dome continues to be active and produce explosions and small pyroclastic flows from time to time, generating ash plumes rising to 7-10,000 ft such as today.

Activity at the volcano continues to increase. A relatively long phase of strong volcanic tremor today and high levels of SO2 output suggests that the rise of magma is accelerating. A continuous plume of steam and some ash was observed last night reaching 1 km high, in addition to intermittent explosions. Lava glow at night is now strong.

A small seismic swarm, likely caused by the rise of another new small batch of magma, occurred this morning at the volcano. The hyopcenters were located 4 km SW of the Arenas crater at depths between 4-6 km, INGEOMINAS reported.

An earthquake swarm with hundreds of earthquakes up to magnitudes near 4 occurred between 9-10 May at about 10 km depth on the submarine prolongation of the SW rift zone (Reykjanes Ridge). Likely, it was caused by a shallow magmatic intrusion, but there are no reports suggesting a submarine eruption.Popocatépetl (Central Mexico): The activity continued to increase over the past days and CENAPRED raised the alert level to Yellow Phase 3 this morning. The volcano has been producing frequent sequences of continuous steam and ash emissions as well as discrete vulcanian-type explosions that throw glowing bombs to several hundred meters distance from the crater and create ash plumes up to about 2 km high. Read all SERNAGEOMIN has recently raised the alert back to yellow after new small explosions occurred at the volcano and incandescence was observed at the summit crater. A small but persistent steam-and-ash plume has been rising about 350 m from the volcano. Interestingly, little change in the seismic activity has been noticed with the incandescence and explosions, so it is not clear whether this new activity is caused by fresh magma rising towards the surface.

Seismic and surface activity remain moderate with ash emissions and intermittent strong strombolian to vulcanian explosions which sometimes are accompanied by ground vibration and strong shock waves that rattle windows and doors in nearby areas. Read all

Possible eruptions have started at the volcano. Pilots reported several volcanic ash plumes from the volcano in the past days although VAAC Buenos Aires could not identify ash on satellite imagery.

The activity continued to increase over the past days and CENAPRED raised the alert level to Yellow Phase 3 this morning. The volcano has been producing frequent sequences of continuous steam and ash emissions as well as discrete vulcanian-type explosions that throw glowing bombs to several hundred meters distance from the crater and create ash plumes up to about 2 km high.
