Colima volcano (Mexico): activity report - less pyroclastic flows, but explosions
Mon, 13 Jul 2015, 21:36 | BY: T
Ash explosion from Colima today
Field report: activity of pyroclastic flows rapidly increased on Saturday 11 July, with powerful pyroclastic flows that traveled as far as approx. 10 km, mainly into the ravines of La Lumbre and Montegrande on the SW and S sides. When arriving in Colima Sunday noon, pyroclastic flows on the southern side were nearly continuous although only the base of the volcano was visible. In the course of the evening and the night, this activity decreased a lot. Judging from diffuse glow visible through cloud cover, it seems a coherent lava flow was active on the upper S side.
Today, no pyroclastic flows have been seen (but most of the time, the volcano has been in clouds), but several moderately sized ash plumes rose from the summit, presumably caused by explosions.

Colima volcano (Mexico) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 July-14 July 2015 (New Activity / Unrest)
In a 7 July bulletin, the Unidad Estatal de Protección Civil de Colima reported that during the previous week explosions from a fast-growing lava dome at Colima generated ash plumes that rose 3 km above the crater. Incandescent rock avalanches, from explosions and the lava dome overtopping the crater rim, descended the flanks. Ashfall was reported in various communities downwind. ... Read all
