Santa Maria volcano (Guatemala) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 April-28 April 2020 (Continuing Activity)
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 1.2 km NW, W, and SW. Avalanches of blocks descended the S, SE, and E flanks of Caliente cone. Ashfall was recorded in areas downwind including Loma Linda, San Marcos Palajunoj, and La Florida and Santa Marta fincas.
