INSIVUMEH reported that almost daily ash plumes from Santa Maria's Santiaguito lava-dome complex rose 500-900 m and drifted W and SW during 19-27 September, depositing ash on the flanks. Extrusion continued at the summit dome complex, mainly from the W part of the dome. Avalanches produced by the active dome were sometimes incandescent and predominantly descended the W flank, though some also traveled S and SW.
The avalanches often reached vegetated areas on the flanks.
