Results obtained by the first intensive airborne surveys carried out at Volcán Villarrica (39°S) in Southern Chile, are presented. These campaigns included the use of a scanner laser system, for detecting the glacier surface topography, and a helicopter-borne ice penetrating radar, for...

San Martin Tuxtla Volcano, the largest and highest edifice in the Tuxtla Volcanic Field, had explosive eruptions in 1664 and 1793. This volcano poses the highest hazard for the growing population centers surrounding it. The impacts and deposits of the 1793 eruption have been studied recently,...

Laptop computers are vital components of critical infrastructure sectors and a common tool in broader society. As they become more widely used, their exposure to volcanic hazards will increase. Therefore, understanding how laptops will function in volcanic environments is necessary to provide...

The importance of disaster reduction has gained increased awareness within the international development community and thereby highlighted a need for a preliminary assessment of natural hazard risk in developing countries of the Asia–Pacific, including that for volcanic eruption. In this...

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...

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...
