Pacaya in Guatemala continues to be very active, with repeated pulses of volcanic ash rising as high as 4300 meters. Lava flows are active in the south, emerging relatively far down the flank. MIROVA is registering high thermal radiation with 887 MW output. CONRED reported yesterday that a lava flow reached farmland and started fires. Firefighters had to move in to extinguish the burning grassland. Three homesteads were affected.
