Sakurajima (Kyushu, Japan): It seems that the latest cycle of increased activity has ended: after several days of intense activity, culminating in larger explosions on 14 and 15 May, the volcano has been "taking a rest" lasting about 2 days. This morning, only a small explosion was recorded.

Pavlov (Alaska Peninsula, USA): The eruption continues with lava fountaining at the summit that feeds a lava flow now over 100 m long and produces a continuous ash, steam, and gas plume extending downwind from the volcano for 50 to 100 km at an altitude of about 20,000 ft above sea level. This morning the cloud was carried to the southeast. Satellite images show persistent elevated surface temperatures at the summit and on the northwest flank.
Seismic activity remains elevated with nearly continuous tremor recorded on the seismic network.

Popocatépetl (Central Mexico): Activity remains intense. Last night at 22:14 and this morning at 00:29 h local time, two strong explosions occurred and ejected incandescent fragments on all the volcano´s flanks to distances of up to 1,500 m from the crater. The explosions triggered an eruption plume rising at least 3 km above the volcano, drifting northeast.

Telica (Nicaragua): Seismic activity has returned (for now) to relatively low levels today. This follows many small earthquake swarms that occurred during the past week.

San Cristobal (Nicaragua): Seismic activity has generally remained weak recently.

Masaya (Nicaragua): Seismic activity has remained at normal, generally low levels during the past weeks. Occasionally, phases of weak increased tremor are visible.

Galeras (Colombia): A small series of ash emissions occurred in the morning of 16 May, following a weak increase in seismic activity during the past week.

Pavlov (Alaska Peninsula, USA): 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. ... Lees alle

MODIS hot spot data (past 2 days) for Tolbachik volcano (ModVolc, Univ. Hawaii)
Kizimen (Kamchatka): 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) ... Lees alle

Current seismic recording from Popocatépetl
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. ...
