Volcan Fuego de Colima (Mexico): Volcanological, petrological and geochemical monitoring of the most active volcano in North America.

Volcan Fuego de Colima (Mexico): Volcanological, petrological & geochemical monitoring of the
most active volcano in North America.
Dr.Ivan Savov, School of Earth and Environment, University of Leeds.
The aim of my talk will be to introduce the geology and volcanology of young (Holocene) lavas and ash (tephra) deposits from the large Colima Volcanic Complex (CVC) in Western Mexico. I will be emphasising the chronological, petrological and geochemical evolution of the currently active vent of Volcano Fuego de Colima (Mexico). The CVC has experienced numerous sub-Plinian to Plinian eruptions (better-known 1980 eruption of Mt.St.Helens in the USA or 1991 eruption of Pinatubo in the Philippines). CVC also developed at least 12 large calderas, and produced the largest debris avalanche deposit on Earth. Many of these eruptions resulted in extensive ashfalls across vast areas of Mexico and beyond. Ashfall is a major volcanic hazard as it is causes roof and building collapse, respiratory problems to humans and animals, contaminates water supplies, and causing widespread economic losses to the aviation industry. Importantly, over the last couple of decades, my collaborators and I have made a great progress in deciphering the Holocene eruptive history of this very active and highly explosive large stratovolcano. Some tantalising insights have come to light and we think those will be rather useful for future volcano monitoring and realistic hazard assessment of this dangerous andesitic volcano.
PLEASE NOTE NEW VENUE:
The meeting will take place in the Maurice Keyworth Building (Lecture Theatre G.02) which, due to the unavailability of the Michael Sadler, will be our new venue for the foreseeable future.
Until we have used the venue, we are not sure if we will be able to provide refreshments after talks.
How to get to the Maurice Keyworth Building:
The Maurice Keyworth Building (which some will know as the old Leeds Grammar School) is part of the Leeds University Business School and is found on the Western Campus which is on the west side of Clarendon Road opposite to the main campus. On entering the building go past reception and the lecture theatre (G.02) is on the left.
Maurice Keyworth is about a 5–10 -minute walk from our old venue in the Michael Sadler Building but, if travelling by car, instead of using the Orange Zone parking, there is the possibility of parking closer on surrounding roads. These are:
Lyddon Terrace: Although surrounded by university buildings, is a public road and has no parking restrictions. It is accessed off Clarendon Road via University Road, turning right before the barrier. Woodsley Road (off Clarendon Road) and St Johns Terrace: (off Moorland Road) Both have unrestricted parking after 6.00 pm on the side bordering the campus (permit parking only on sides with houses)
Blue badge holders: Park in the Western Campus parking facilities (accessed off Clarendon Road) where there are spaces before the barrier. If these are all occupied then contact Security via the speaker on the barrier, state your business, and they will raise it. Exit is via the one-way system onto Moorland Road.
Maurice Keyworth Building is No. 19 (Business School, Maurice Keyworth Building)
