MODIS hot spot data (past 7 days) for Pavlov volcano (ModVolc, Univ. Hawaii)

Ash emissions from Galeras on 16 May (INGEOMINAS)
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.
