Santa María, Guatemala

Based on analysis of satellite imagery, the Washington VAAC reported that on 12 February ash puffs from Santa María’s Santiaguito lava dome complex drifted WSW and W. On 16 and 17 February, INSIVUMEH reported that explosions produced ash plumes that rose to altitudes of 2.7-3.3 km (8,900-10,800 ft) a.s.l. and drifted SW. Small pyroclastic flows on 16 February descended the SE flank and reached the Nima I river. On 17 February, incandescent avalanches were noted and fumarolic plumes drifted SW.
