Dome growth continues at Colima 23 January 2010

Low-level eruptive activity at Colima, the most active volcano in Mexico, has been causing concern recently. On 26 November 2009 an overflight reported that the lava dome, which began its current phase of growth in February 2007, filled 80% of the summit crater. According to reports of the most recent overflight, which took place on 20 January 2010, the dome now fills 85% of the crater and has reached 65 metres in height. The local civil protection authority, the Unidad Estatal de Protección Civil y Bomberos (UEPCB), reports that there is a risk of dome collapses taking place, particularly in the south-western area of the summit where instability is greatest, but that the current activity of the volcano ‘is not a risk to the surrounding population’. A 7.5-km-radius exclusion zone remains in force around the volcano.

Mexico: Colima’s restlessness causes concern 3 December 2009

Colima volcano in western Mexico has the distinction of being the most active volcano in that country: over seventy eruptions (since 7690 BC ± 500 years) are listed by the Global Volcanism Program, with the most recent bout of activity beginning in November 1997 and still ongoing. The volcano is situated in a densely populated region, with over 30,000 people living within 40 km of its crater – as a result it is one of the sixteen Decade Volcanoes, active volcanoes seen as posing particularly high risks to populous areas.

During 2009 Colima (also known as Volcán de Fuego) has been emitting white and grey plumes that have reached as high as 6.4 km above sea level, and there have been occasional ejections of incandescent material. Both ground and air exclusion zones have been imposed around Colima by state civil protection authorities. The high level of activity has been causing some concern in the surrounding area, with reports of a ‘high possibility’ that the volcano is preparing to erupt; the authorities have responded by playing down reports of imminent risks, while stressing the need for local people to remain watchful and prepared to respond to any increase in activity.

On 26 November there was an overflight of the volcano which reported that the lava dome within the main crater of Colima, which has been growing since February 2007, now blocks 80% of the crater and has attained a height of 60 metres (another news source gives a height of 45 metres, diameter of 270 metres and volume of 2 million cubic metres). Material has accumulated against the western wall of the crater and against a section of the southern wall, which could produce occasional landslides down the western slopes of the volcano. High temperatures were reported within the crater.

Fresh lava flows and ejections of incandescent material some 50 metres from the crater were reported on 2 December. The latest available bulletin (2 December) from the Unidad Estatal de Protección Civil Colima reports continuous fumarolic activity and the ejection of incandescent material, without any damage or injuries.

A new web-based resource is available providing information about the interesting and active Mexican volcano Colima.

The Colima Volcano Database, developed by a group of researchers at the Centro de Geociencias at the Universidad Nacional Autónoma de México (with collaborators from other institutions), includes details of the eruptive history of the Colima Volcanic Complex, a hazard map, data from ongoing research, bibliographies, pictures and films. A mapserver is also under development.

The site is constantly updated, and new information is requested: anyone who has data, picture or publications not already included is invited to contact the website team who will add it to the database.
