The eruption continues with lava fountaining, an active lava flow and ash emissions, accompanied by continuous seismic tremor. Aerial observations suggest that the interaction of lava and ice on the upper slope of the volcano create mud flows and pyroclastic flows. ... [more]

Activity remains elevated, but the number and size of explosions have decreased during the past 2 days. CENAPRED made an overflight and found that the series of recent explosions since 14 May, in particular the two that occurred on the night of the 16th to 17th, have excavated a crater of approx. 200 m diameter and 40 m depth in the lava dome. The rest of the dome's surface is covered by fragments from the explosions. [more]

A small series of ash emissions occurred in the morning of 16 May, following a weak increase in seismic activity during the past week. [more]

The eruption continues. The volcano produces a lava flow on the northwest flank. Interaction of the lava flow and ice, producing debris flows, as well as possible explosions at the vent produce a steam-ash plume rising up to about 20,000 ft. above sea level. ... [more]

The volcano has calmed down a bit compared to the previous week, which is also apparent on recent seismograms. No recent explosions or ash falls were reported. [more]

Strombolian activity has returned or increased and is now ejecting incandescent material to heights of 100 m. Seismic data seem currently not available from INSIVUMEH's website. [more]

Relatively strong explosions occurred last night (at 20:21 h local time 14 May) and this morning at 01:46 h (local time). Both eruptions generated columns of steam and ash rising 3 km and the latter explosion ejected incandescent fragments over all the volcano flanks to maximum distances of 1,500 m. ... [more]

Activity has remained generally elevated and seems to have increased yesterday. Current seismic recordings show strong explosion signals and an increase in tremor. A small lava overflow is currently visible from the NE crater. [more]

Lava dome growth continues. This morning, an explosion and/or a partial collapse produced a volcanic ash cloud rising to 15,000 ft (4.7 km) altitude this morning by VAAC Tokyo. ... [more]

Activity remains elevated as new magma continues to rise to the summit at increased rate. The volcano produces intense steaming and occasional explosions that generate steam and ash plumes up to 3 km height and throw incandescent blocks to distances of 700 m. Phases of moderate continuous tremor and several volcano-tectonic earthquakes up to magnitudes 2 accompany this process. Authorities are starting preparations for evacuations should it further increase. ... [more]
