INSIVUMEH reported that during 4-11 May daily explosions at Santa María's Santiaguito lava-dome complex generated ash plumes that rose as high as 1.1 km above the summit and drifted W, SW, and S. Collapses of blocky lava from Caliente dome sent avalanches down the SE, S, SW, and W flanks, sometimes reaching the base, and causing minor ashfall around the volcano. Ashfall was also reported in San Marcos (8 km SW) and Loma Linda Palajunoj (6 km WSW) during 5-6 and 10-11 May.
