Based on webcam and satellite images, the Mexico City MWO, and pilot observations, the Washington VAAC reported that during 18-24 January ash plumes from Colima rose to altitudes of 4.1-6.7 km (15,000-25,000 ft) a.s.l. and drifted in multiple directions. On 19 January explosions were recorded by the webcam and noted by the Jalisco Civil protection agency; ashfall was also reported in Comala and Cuauhtémoc by the agency.
A strong thermal anomaly was identified in satellite images. Remnant ash clouds were centered about 350 km SE on 20 January and about 185 km S on 22 January. A large ash plume rose to an altitude of 10.7 km (35,000 ft) a.s.l. on 23 January and drifted NE.
