Santa María / Santiaguito (Guatemala): The new lava flow on the eastern flank of the Caliente dome continues to advance slowly and produce avalanches. Small explosions occurred, generating ash plumes up to 700 m high. Rainfalls caused a medium-sized lahar in the Nima I river yesterday at dawn.
Fuego (Guatemala): The lava flow has disappeared and explosive activity in turn increased. The observatory reported ash plumes up to 600 m high and drifting SW to 8 km distance. Shock waves accompanied the stronger explosions. Rainfalls triggered a lahar in the Las Lajas river canyon.
