Guatemala - Two lava flows are active on the upper slopes of the volcano at the moment, to the Taniluya (south) and Ceniza canyon (SE). The effusive activity started on 11 Nov and increased on 18 November, reaching a length of 600 m. Constant avalanches detach from the flow fronts. At the same time, explosive activity at the summit crater remained at low to moderate levels, with strombolian explosions that produce ash plumes of up to 800 m height and incandescent jets visible from distance. Some of the explosions generate shock waves that can be felt and heard in up to 15 km distance, causing roofs, doors and windows of houses to rattle. Fine ash fall occurred in Panimaché, Morelia abd Sangre de Cristo. -Volcano Discovery

Weak explosions at Yasur: Geohazards reports that the volcano continues to produce near-continuous ash emissions while explosions are relatively weak at the Yasur volcano on Vanuatu. This phase of ash emissions began on 3 November and are likely to continue into the coming days and weeks. Yasur Alert Level is still maintained at Level 1. Villages and communities located close and far away from the volcano, especially those in the prevailing trade winds direction (NW) are likely to receive ash falls. - Volcano Discovery
