Santa Maria / Santiaguito volcano (Guatemala), activity update: moderate explosions at intervals of 15 minutes

Tuesday Feb 28, 2012 11:05 AM | BY: T

Santiaguito volcano in Guatemala has been displaying a slightly elevated state of activity in recent days. INSIVUMEH reports moderate explosions about every 15 minutes that eject plumes of gray ash tot 600 and 800 meters above the crater, and producing an ash plume drifting to the west and SW until dissipating at about 15 km distance.
Light ash falls from these eruptions frequently occur in the villages San Marcos, Buena Vista and Palajunoj and the El Faro, Florida, and Monte Claro Fincas.
Crater glow at the summit of the lava dome is well visible at night, and a blocky lava flow with constant avalanches of blocks rolling down to tits base continues to be active, raising secondary ash plumes.
The monitoring network records the explosions on seismic signals.
