UB geologists to help communicate the dangers of Colombian volcano

BUFFALO, N.Y. -- During the past decade, residents of Pasto, Colombia, and neighboring villages near Galeras, Colombia's most dangerous volcano, have been threatened with evacuation, but compliance varies. With each new eruption -- the most recent explosion occurred June 7-9 -- Colombian officials have grown increasingly concerned about the safety of the residents who live within striking distance of Galeras, located 700 km from Bogota.

Now, geologists from the University at Buffalo and the Universidad de Nariño have organized a special workshop in Colombia designed to tackle the communication issue, with support from the National Science Foundation and the Universidad de Nariño.

The purpose is to develop a consensus as to how best to raise awareness and protect these communities from dangerous eruptions at Galeras.

Unlike most scientific workshops, which are exclusively attended by scientists, this program will include the active participation of local residents and government officials working together with the scientists in all of the workshop sessions.

From July 6-11, Michael F. Sheridan, Ph.D., an internationally renowned volcanologist and director of UB's Center for Geohazards Studies, and Gustavo Cordoba, Ph.D., a post-doctoral researcher in the UB center, will run the workshop on "Knowledge Sharing and Collaboration in Volcanic Risk Mitigation at Galeras Volcano, Colombia." Complete information is at http://galerasworkshop09.weebly.com/index.html.

The first half of the workshop, which will feature professors from the UB Department of Geology, the Universidad de Nariño in Colombia, officials from the local and federal government and the Red Cross, among others, will cover the history of volcanic eruptions at Galeras, volcanic crisis management, the physics and modeling of explosive volcanism and discussions about crisis management at Soufriere Hills Volcano, Chaiten Volcano,Vesuvius and others.

The second half of the workshop will begin July 10 with a session called "The People Speak."

Sheridan said that this part of the workshop puts a spotlight on the critical connection between local populations affected by an adjacent hazard and the level of scientific understanding and certainty -- or the lack of it -- about that hazard.

"The villagers feel they are safe," said Sheridan.

In one example, he said, some of them have said that there is a sacred stone with petroglyphs on it that lies directly in the path where volcanic debris is expected to flow, but it has been there for 500 years and has never been damaged by eruptions at Galeras.
