A second into the explosion of Colima on 19 Jan evening
Vulcanian-type (sudden, but very strong) explosions continue to occur at the volcano. Following the powerful eruption early on Thu 19 Jan, another, an even stronger explosion - one of the most energetic in recent years - occurred in the evening of the same day at 22:16.
A minute later, a large ash plume rises while bombs have impacted all over the cone
It started with a violent cannon-shot like explosion that propelled incandescent bombs to heights well over 2000 meters and covered the whole cone and its lower flanks with impacts, igniting bush fires. Pyroclastic flows from collapsing material also descended the flanks and an ash plume rose to several kilometers height:
A similarly impressive explosion had already occurred in the early morning the same day (around 04:30 am):
Following this event, the volcano has been calmer, still having explosions, but only of small to modest size. Whether the two powerful eruptions on 19 Jan have (temporarily) drained the energy (and emptied the magma column) will remain to be seen.
