Wed, 15 Jan 2020, 06:00
06:00 AM | BY: VN
INSIVUMEH reported that explosions at Santa María's Santiaguito lava-dome complex generated ash plumes that rose 800-900 m above the crater and drifted as far as 1.4 km W and SW. INSIVUMEH noted that ashfall was likely in areas downwind. Avalanches of material descended the NW, SW, and SE flanks of Caliente cone.
