Volcanos

Roundup of Global Volcanic Activity:

Pacaya (Guatemala): According to INSIVUMEH, the eruption has considerably slowed down since last evening around 19:15 (local time), although weather prevented detailed observations. Activity at the summit decreased to moderate strombolian explosions with ejections reaching 100 m height and degassing. The tremor signal is still saturated, suggesting that the effusion of lava continues. A strong thermal anomaly, corresponding to the new lava flows, is now visible on satellite data. The ongoing eruption of the volcano involved the opening of at least two effusive fissure vents on the northern and southern base of the Mackenney cone (this info according to images and maps published by CONRED, although CONRED / INSIVUMEH at the same time report 3 vents on the east, west and south flank). These fissures feed two large (and possibly one smaller third) lava flows that have reached lengths of 3-5 km length and are several hundred metres wide at their fronts (up to 800 m on the western side). The lava flows have burned extensive areas of farmland and woods and are close to some villages.
