Roundup of Global Volcanic Activity
Tacaná volcano (Mexico / Guatemala): shallow earthquakes A number of shallow earthquakes has occurred recently under the volcano. The largest was a magnitude 4.0 event at 5 km depth under the eastern flank. No reports of unusual activity at the volcano are available.
Popocatépetl volcano (Central Mexico) activity update No significant changes in activity have occurred over the past weeks. Following a very quiet period, the volcano has become a bit more active in the past days with an increased number of steam and gas emissions.
Ubinas volcano (Peru): small explosion A small explosion occurred this morning (09:15 local time) at the volcano and produced a small ash plume.
Batu Tara volcano (Sunda Islands, Indonesia) activity update Strombolian activity continues. An ash plume from a stronger event was detected this morning on satellite imagery (VAAC Darwin).
Santa María / Santiaguito volcano (Guatemala) activity update Activity remains low. The observatory reported sporadic small explosions and small avalanches from active block lava flows on the east and southeast flanks of the Caliente dome.
Fuego volcano (Guatemala) activity update The new lava flow continues to slowly advance on the upper SE flank and reached a length of 200 m this morning. Strombolian-type eExplosions have been relatively frequent and weak to moderate in size, generating ash plumes up to 800 m tall.
Karymsky volcano (Kamchatka) activity update According to KVERT, strombolian to vulcanian explosive activity continues. Recorded seismic activity was moderate.
Bezymianny volcano (Central Kamchatka Depression, Kamchatka) activity update: steaming, weak seismic activity Very weak activity continues at the volcano. During the past week, KVERT registered shallow earthquakes. Video data captured minor gas-and-steam plumes rising from the volcano.
Sinabung volcano (Sumatra, Indonesia) activity update VSI published a new status report which indicates that effusive activity at the volcano still continues. The lava lobe still grows at very slow rate with an overall decreasing trend over the past months.
Kusatsu-Shirane volcano (Honshu, Japan) activity update: seismic unrest JMA reported that deformation of Kusatsu-Shiranesan’s crater and the elevated temperatures which began earlier in March, continued during 25-30 June. This activity has been focused in the area immediately of N of Mizugama crater. Some seismicity was also reported, although tremor was absent. The Alert Level remains at 2 (on a scale of 1-5).
