Pacaya: Update 09.10.20

The Guatemalan volcano Pacaya is leading the headlines today because it erupts at least 2 lava flows. They originate from the base of the intracrater cone in the McKenney crater and generate a thermal signal with 333 MW power. The flows flow on the southeast and northeast flanks and split into several arms. Debris avalanches descend from the front of the flows. Exact longitude data are still missing. INSIVUMEH reported yesterday that there is only one stream on the south flank. It had a length of 250 m. The longer of the two rivers will be of this size today. Furthermore, the Pacaya is strombolian active and lets glowing tephra rise up to 100 m high. The eruption can be seen from Guatemala City. Numerous pictures were shared on Twitter.
