Activity at the summit of Pacaya volcano has been increasing, after a month of quiet. Seismometers recorded 97 explosions in the 24 hours to 16th July. Most ejected material is falling inside the crater. There are some pyroclastic flows down the south flank of the volcano. There is a small amount of ash emission from the crater. Pacaya volcano had a large summit eruption, and flank lava flow in May and June 2010.
