Colima volcano (Mexico): frequent explosions and rockfalls make for Easter tourist attraction

Current seismic recording from Colima volcano (Soma station, Univ. Colima)The "Volcano of Fire" has become a tourist attraction with now up to 200 weak to moderate explosions per day, and frequent incandescent rockfalls / small pyroclastic flows that descend the flank of the volcano to a length of up to 1.5 km and are a spectacular view at night.
Melchor Ursua Quiroz, director of the State's Civil Protection unit, said that the Fuego de Colima volcano is currently the most active of the country, and has recently increased its explosive activity. In an article in the El Universal newspaper, he "rules out" any risk for the population. A 8 km exclusion zone is in place around the volcano and the governments of Colima and Jalisco are on permanent alert.

Explosions and incandescent rockfalls sometimes forming small pyroclastic flows on the flanks of the volcano remain frequent. The rockfalls from the growing dome provide a spectacular show at night. [more]
Colima volcano (Mexico): increasing activity, glowing rockfalls and small pyroclastic flows on the flanks
Wednesday, Mar 27, 2013
Activity has continued to increase both internally and at the surface, with frequent explosions and glowing rockfalls and small pyroclastic flows traveling down the flank of the volcano. [more]

Small explosions from the growing dome, associated rockfalls and volcanic earthquakes have continued to increase in amplitude and frequency during the past days and weeks. [more]

Activity at the volcano continues to increase. The new lava dome in the summit crater has apparently grown enough that incandescent lava could soon start descending into the Lumbre canyon on the western flank and produce pyroclastic flows, scientists from the university of Colima have warned. ...

Background: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.
