The collapsing eruption column loaded with ash and rock fragments has not yet fully developed, but the flanks of the volcano are already covered by the impacts of ballistics.

Colima volcano is one of the most active volcanoes in North America and one of the potentially most dangerous ones. It has had more than 30 periods of eruptions since 1585, including several significant eruptions in the late 1990s. Scientific monitoring of the volcano began 20 years ago.

Construction of lava domes, vulcanian eruptions and strombolian activity. In near-constant activity since 1994. Last earthquakes nearby
Seismic signal from Colima on 25 Aug 2017 (image: University of Colima)
There are signs that the volcano might be entering a new eruptive phase. Along with an increase of volcanic earthquakes, a small explosion was observed yesterday night (at 00:50 local time on 25 Aug 2017). ...more
According to a special report from the University of Colima, other (non-observed) small explosions have followed since. The quakes detected yesterday were mainly of long-period and high-frequency type, and likely correspond to a the movement of a new batch of magma that has started to rise inside the volcano and probably will soon begin building a new lava dome. Already since 2 weeks, earthquake activity has been above background, the report noted, including events located directly under the crater. New explosive / effusive activity can be expected to resume in the near future. [less]
The volcano has remained calm since the series of powerful explosions in Jan-Feb this year. A recent report by scientists from the Universidad de Colima mentioned ongoing seismic activity as well as very week explosions.
The volcano has remained very calm, with only a few and small ash emissions occurring at intervals of many hours. Since the violent explosion on 3 Feb afternoon, no more vulcanian eruptions have occurred. ...more
It seems likely that the recent phase of violent explosion, probably caused by a pulse of fresh, gas-rich magma, has ended for now. [less]
Powerful explosion of Colima Friday afternoon 17:05 local time
A large vulcanian explosion happened on Friday afternoon (around 17:30 local time), generating an ash column that rose approx 4 km and generated a pyroclastic flow on the eastern flank. ...more
This explosion was the first significant event since a similar event on 26 Jan. During the interval and since the explosion on Friday, the volcano has had only few and very week ash puffs at irregular intervals of average 8-12 hours, with no visible ejecta nor incandescence from the crater. [less]
Strong explosion at Colima volcano yesterday morning (22:03 local time on 26 Jan)
The activity at the volcano remains relatively high. Explosions of various sizes occur at irregular intervals (typically few hours). ...more
The largest generate spectacular eruption columns reaching several kilometer height with ballistic impacts all over the cone and sometimes small pyroclastic flows by collapsing material of the eruption column. Part of our team is on its way to location and will hopefully be able to report more in detail soon. [less]
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. ...more
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 minute later, a large ash plume rises while bombs have impacted all over the cone

The series of strong vulcanian explosions continues. ...more
Some of them are large enough to send incandescent bombs all over the summit cone and produce small pyroclastic flows and eruption lightning. For those interested in joining us on a last-minute volcano eruption tour, we offer a Colima Volcano Special from 29 Jan - 2 Feb! [less]
Powerful explosion of Colima Sunday morning 11:07 local time (image: Christian Villicaña / Colima de Ayer / facebook)
The volcano's activity remains above average. Vulcanian-type explosions from the summit crater occur at intervals of several hours and are sometimes very powerful, generating dense ash columns that rise 2-4 km, and cover the upper slopes of the volcano with bombs. ...more
Some of them also generate small pyroclastic flows descending the steep upper flank. [less]
Vulcanian eruption at Colima yesterday morning (image: Hernando Rivera)
Explosions continue to occur at the volcano. Although their frequency has decreased a lot compared to a few weeks ago, now often with intervals of 10+ hours, they are now often stronger, generating ash columns that rise 3-4 km above the volcano's summit crater and showering the entire flank with incandescent bombs such as the one our friend Hernando took yesterday morning (attached image). ...more
The lava flow on the southern side is no longer active. What causes the change in activity is difficult to say, but it likely reflects a decrease in the magma supply rate, i.e. lower speed of magma rise inside the conduit, enabling a greater pressure build-up released less frequently, but during larger explosions.

Colima volcano is one of the most active in North America and one of the potentially most dangerous ones. It has had more than 30 periods of eruptions since 1585, including several significant eruptions in the late 1990s. Scientific monitoring of the volcano began 20 years ago.
The Colima volcanic complex is the most prominent volcanic center of the western Mexican Volcanic Belt. It consists of two southward-younging volcanoes, Nevado de Colima (the 4320 m high point of the complex) on the north and the 3850-m-high historically active Volcán de Colima at the south.
A group of cinder cones of probable late-Pleistocene age is located on the floor of the Colima graben west and east of the Colima complex. Volcán de Colima (also known as Volcán Fuego) is a youthful stratovolcano constructed within a 5-km-wide caldera, breached to the south, that has been the source of large debris avalanches. Major slope failures have occurred repeatedly from both the Nevado and Colima cones, and have produced a thick apron of debris-avalanche deposits on three sides of the complex. Frequent historical eruptions date back to the 16th century. Occasional major explosive eruptions (most recently in 1913) have destroyed the summit and left a deep, steep-sided crater that was slowly refilled and then overtopped by lava dome growth.
