Santiaguito volcano (Guatemala): large mud flows triggered by rainfall
As expected, heavy rainfalls triggered a hot lahar (turbulent flow of mud, boulders and ash deposits mixed with water) that traveled down the Nima I river valley yesterday. The lahar carried lava blocks up to 2 m in diameter as well as many tree branches and trunks.

Abundant steam and sulfur gasses were released from the flowing masses. The lahar passed near the volcano observatory like a mix of "cement", where it let the ground vibrate, increased water content and speed as it reached the Samala river.
Similar rainfall could cause other lahars in the river San Isidro, the other important tributary of the Samala river. (INSIVUMEH)
