Pacaya (Guatemala) - Report for 6 February-12 February 2019

Actividad volcánica (SI/USGS) - Mié, 2019/02/13 - 07:18

INSIVUMEH reported that during 7-12 February Strombolian explosions at Pacaya?s Mackenney Crater ejected material as high as 25 m above the crater rim. Multiple lava flows traveled 10-250 m down the NW flank, advancing towards Cerro Chino, and on the E flank. Minor avalanches of material from lava-flow fronts descended the flanks.
