Chikurachki (Paramushir Island): (19 Aug) The new eruptive phase, detected through satellite images since yesterday, continues. Ash emissions have increased today and form a plume stretching about 50 km to the NE and reaching the southern tip of Kamchatka. ... [more]

Shiveluch (Kamchatka): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: ... [more]

Suwanose-jima (Ryukyu Islands): Activity has been more intermittent over the past days, but occasional (presumably strombolian) explosions continue to occur, producing small ash plumes that rise up to approx. 2 km altitude and quickly disperse. ... [more]

Santiaguito (Guatemala): A particularly strong vulcanian explosion occurred at the Caliente lava dome this morning (at 06_58 local time), sending a massive mushroom-shaped ash plume to several kilometers height that eventually reached approx. 20,000 ft or 7 km altitude). The cone and its immediate surroundings were showered by volcanic blocks and bombs and collapsing material from the eruption produced avalanches that engulfed the cone on several sides (pyroclastic flows). ...

Shiveluch (Kamchatka): The activity of the volcano remains essentially unchanged at currently low to moderate levels. The slow growth of the lava dome continues as viscous (sticky) lava accumulates in the dome. A (small) part of the inherently unstable dome collapsed yesterday morning and generated a pyroclastic flow that traveled down the SW valley between the dome and the remnants of the 1964 collapse scar, which forms a horse-show shaped wall around the dome. ...
