Santa Maria volcano (Guatemala) - Smithsonian / USGS Weekly Volcanic Activity Report for 29 July-4 August 2020 (Continuing Activity)

INSIVUMEH reported that during 29 July-4 August explosions at Santa María's Santiaguito lava-dome complex generated ash plumes that rose 900 m above the crater and drifted as far as 1 km W and SW. Avalanches of blocks descended the SE, S, and SW flanks of Caliente cone; some reached the base of the cone and were sometimes accompanied by small pyroclastic flows. Minor ashfall was noted in areas downwind including San Marcos (10 km SW), Loma Linda (6 km WSW), and Palajunoj (18 km SSW) during 29-30 July and 2-4 August.
