Renewed volcanic activity near Mammoth Lakes, California, in the form of dome-collapse pyroclastic density currents (PDCs) from either a new eruption at Mammoth Mountain or the Inyo craters would pose a significant hazard to critical infrastructure there. This paper compares the risk from PDC...

Volcanic activity has caused significant hazards to numerous airports worldwide, with local to far-ranging effects on travelers and commerce. Analysis of a new compilation of incidents of airports impacted by volcanic activity from 1944 through 2006 reveals that, at a minimum, 101 airports in 28...

Volcanic-ash clouds are a known hazard to aviation, requiring that aircraft be warned away from ash-contaminated airspace. The exposure of aviation to potential hazards from volcanoes in the United States is significant. In support of existing interagency operations to detect and track...

Nevado de Toluca Volcano (NTV), located in central Mexico, is a large stratovolcano, with an explosive history. The area is one of the most important developing centers (2 millions) in Mexico and in the last 30 yrs large population growth and expansion have increased the potential risk in case...

Large explosive eruptions have the potential to distribute heavy ashfalls across large areas, resulting in physical and chemical impacts on agriculture, and economic and psycho-social impacts on rural communities. This study investigates how affected agriculture and rural communities have...

Participatory rural appraisal (PRA) methods and philosophies were trialed in a volcanic risk management planning and awareness activity for Savo Island, a historically highly destructive volcano in the Solomon Islands. Through a combination of methods we tried to combine the roles of...

Taiwan is subjected to several natural hazards such as extreme weather, seismic activity or tsunamis excited by earthquakes occurring along the Pacific Ocean subduction zones. Fortunately, Taiwan has not experienced any volcanic activity in historical times, a fact which reinforced the belief...
