Etna's New SE crater this evening
Stromboli (Eolian Islands, Italy): The seismic signal signal has increased and probably shows both increased tremor and continuous rockfalls on the Sciara del Fuoco.
...26 Feb:
Activity has increased significantly, judging from visible and seismic data. Small overflows of lava are again occurring from the NE crater and tremor is at comparably high levels.
Etna (Sicily, Italy): Today, we observed an eruptive episode characterized by strombolian explosions and ash emissions took place from a new "player", the Voragine summit crater (NOT Bocca Nuova).
The New SE crater has stayed calm, but now at night, an incandescent fumarole and some glow from its crater are visible (although the latter could still be from the Voragine).
Santa María / Santiaguito (Guatemala): No changes in activity occurred at the volcano, which continues to produce small to moderate ash explosions from the dome and weakly alimented block lava flows on its flanks.
Pacaya (Guatemala): INSIVUMEH reports that the small explosions have ceased for now, but expects strombolian activity to resume soon, as the seismicity remains elevated.
Fuego (Guatemala): Weak to moderate strombolian explosions with ash plumes rising about 600 m and drifting for 10 km were reported today.
Nevado del Ruiz (Colombia): Increased SO2 emissions are visible today.
Sabancaya (Peru): (26 Feb) A strong seismic swarm and increased fumarolic activity triggered an eruption warning for Sabancaya volcano (Arequipa, Peru) and the Civil Defense of the Regional Government of Arequipa raised the alert level to yellow, which involves implementing actions to prepare for a probable volcanic eruption.
