The volcano's activity seems to have picked up a little bit. Several explosions occurred today, producing ash plumes that rose to up to 14-18,000 ft (4-6 km) altitude and dispersed into westerly directions. ... [more]

Intermittent explosions continue at the volcano from time to time, but with comparably low intensity. No or little glow is visible from the volcano's summit at night, suggesting that the magma column is relatively deep inside the conduit currently. [more]
Wednesday, Jun 01, 2016
The activity of the volcano remains essentially unchanged, currently relatively low: infrequent small to moderate explosions produce ash plumes that rise 1-2 km, accompanying the very slow growth of a lava dome inside the summit crater. [more]

The activity of the volcano has remained essentially unchanged over the past months and is currently relatively low. ... [more]

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.
