Tungurahua, Ecuador

During 25-27 and 30-31 March, IG reported that steam-and-ash plumes from Tungurahua rose to altitudes of 5.5-7 km (18,000-23,000 ft) a.s.l. and drifted NW, NE, E, and SW. On 25 March, ashfall was reported in areas to the SW and lahars traveled down a drainage to the W. On 26 March, lahars traveled down multiple drainages to the W, SW, and S; a lahar in the Mapayacu drainage to the SW carried blocks up to 2 m in diameter. Inclement weather impaired visual observations during 28-29 March.
