The Geological Society of America is currently holding its 2009 Fall Meeting in Portland, Oregon (18-21 October 2009) and with volcanoes featuring prominently in its title, ‘From volcanoes to vineyards – living with dynamic landscapes’, it’s no surprise that there are plenty of volcanic topics in the programme.

Information on particular presentations is regularly updated on the Portland meeting news release page, but as a service to those chiefly interested in things volcanic (and who don’t feel like working their way through the list opening PDF after PDF) I will be summarizing the volcano-related stuff here.

This first post lists contributions from United States Geological Service scientists: the source is this USGS PDF.

Experimental results of carbon sequestration in basaltic rocks (Robert Rosenbauer, USGS) – exploiting the carbon dioxide sequestration potential of basaltic volcanic rocks.

Entrances to tubular caves on Mars? (Glen Cushing, USGS) – imagery from Mars may show entrances to tunnels, possibly volcanic lava tubes.

Can static decompression of magma trigger volcanic eruptions? (Michael Poland, USGS) – the March 2008 explosion at Kilauea may have been triggered by static decompression caused by lava withdrawal from a reservoir beneath the summit caldera: a mechanism that has implications for volcanic hazards worldwide.

A major explosive eruption and aftermath in the Aleutians (Chris Waythomas, USGS) – the geomorphic and ecological impact of the 2008 Kasatochi eruption, particularly in relation to seabirds.

Communicating health hazards of volcanic ash fall (Kristi Wallace, USGS) – a method for significantly improving public hazard communication in relation to volcanic ash fall and air quality hazards.

Virtual volcano tours and geologic concepts (Dina Venezky, USGS) – the use of Google Map technology to provide real-time information about volcanoes around the world.

The Perfect debris flow (Richard Iverson, USGS) – large-scale experiments examining debris-flow dynamics.

Evaluating debris flow hazards by helicopter (Carol Finn, USGS) – dangling experiments over volcanoes from helicopters to evaluate hydrothermal alteration of rocks, which can contribute to destructive debris-flow hazards on volcanic flanks.
