Santiaguito volcano (Guatemala), activity summary 29 Aug - 4 Sep: explosions, lava flows, lahars

06:43 AM | BY: T
INSIVUMEH reported that on 29 August fumarolic plumes from Santa María's Caliente dome rose 250-300 m and drifted SE. Small avalanches were active on the S part of the dome. Explosions on 3 September produced ash plumes that rose 200-800 m above Caliente dome and drifted W and SW.
Four active lava flows generated block avalanches that traveled S down the Rio Nima I and Rio Nima II drainages. On 4 September hot lahars traveled S down the Rio Nima I and San Isidro drainages. The lahar in the San Isidro channel was 30 m wide and 2 m deep, emitted a sulfur odor, and carried blocks up to 1 m in diameter.
