Volcano news: Santa Maria (Guatemala)
Santiaguito volcano (Guatemala): heavy rains trigger mud flows
Friday Nov 06, 2015 06:40 AM | DOOR: T
Heavy rainfalls caused several lahars during the past days. The volcano continues to produce occasional small to moderate explosions from the active Caliente dome.
from the latest VOLCANO: Smithsonian / USGS Weekly Volcanic Activity Report 28 October-3 November 2015:
INSIVUMEH reported that on 30 October heavy rainfall in the area triggered cold lahars which descended Santa María’s Cabello de Ángel (a tributary of Nima I) and San Isidro (tributary of El Tambor) drainages.
The lahar in San Isidro carried blocks that were 1-2 m in diameter. During 30-31 October explosions generated ash plumes that rose 800 m above the crater and drifted SW, causing ashfall in Monte Claro (S).
Ash plumes from explosions rose as high as 1.1 km and drifted SE during 2-3 November; ash fell in finca El Faro (SW flank), La Florida (5 km S), San Marcos (10 km SW), and Palajunoj (18 km SSW).
