At Fuego, the eruption of May 18 generated pyroclastic flows "type Boiling over", according INSIVUMEH.
This phenomenon is caused by a magma reboiling and a tangential outlet of abundant quantities of volcanic material and pyroclastic flows, without explosion.

Both volcanoes remain under close monotoring : considering the rains season already present , lahars are likely to form in the evening or during the night.
