INSIVUMEH reported explosions from Santa María’s Santiaguito lava dome complex during 22-27 May. Resultant ash plumes seen during breaks in cloud cover rose to altitudes of 4.1-4.4 km (13,500-14,400 ft) a.s.l. and drifted S and SW. Ashfall was reported in areas nearby. Avalanches of blocks on the SW flanks were seen and heard. A lahar descended the Nima I river to the S on 25 May.
