Santiaguito volcano (Guatemala): large mud flows triggered by rainfall

Thu, 15 May 2014, 08:24
08:24 AM | BY: T
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)

Ash clouds from Santiaguito on the morning of 9 May 2014 (INSIVUMEH)
A strong eruptive phase occurred yesterday from around 10 am local time and produced a series of pyroclastic flows that affected the southern and eastern slopes of the Caliente lava dome. Associated co-igimbrite ash plumes rose to estimated 7-8 km altitude. read all

Activity remains relatively low and unchanged. Occasional explosions from the lava dome produce small ash plumes generally lower than 1 km. Only few avalanches were reported lately, suggesting that effusion rate has dropped. ... read all

No significant changes in the currently relatively low activity have been reported. Occasional small to moderate explosions and weak avalanches from the active lava flow on the SE side of the dome occurred during 16-17 April. ... read all

Activity has not changed much over the past weeks. The observatory reports moderate explosions ejecting gray ash plumes rising up to about 800 m and causing light ash falls in areas to the west of the lava dome. ... read all
