During our Volcano Special tour to Colima last week, Ingrid and other 3 participants took a scenic overflight in a small charter plane in order to have a closer look at the active lava dome and its viscous flow on the southern flank. A selection of aerial photos from various angles taking while circling the volcano several times at different altitudes is shown. [more]

The mainly effusive activity at the volcano continues with little changes. ... [more]
Sunday, Nov 20, 2016
The volcano's activity remains as (very) slow extrusion of viscous lava. The lava flow on the upper southern flank is still active, about 500 m long and forms a flat, broad tongue. ... [more]
Tuesday, Nov 15, 2016
The activity has been slowly increasing as the new lava dome in the summit crater continues to grow. It is now over-spilling the lowest point of the southern crater wall where a small lava flow is descending on the upper slope. ... [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.
