Volcano Societal Impacts

Featuring Angie Diefenbach

Angie Diefenbach:

My name is Angie Diefenbach, Im a geologist with the U.S. Geological Survey Cascades Volcano Observatory.

I use various geospatial data sets and GIS, Geographic Information Systems software to study volcanic eruptions and their impacts on society.

The US and its territories are home to about 170 active volcanoes, which means that millions of our citizens are at risk from volcanic hazards.

Traditionally as geologists we have looked at the physical base hazards of volcanoes by mapping out where previous hazards have gone now were trying to look at what the societal impacts are by seeing what is in those hazard zones.

I take hazards assessments that were produced by the USGS and the hazard zones and put them into a GIS and basically just a mapping and I overlay these boundaries on top of all this data and you will see what communities intersect these hazard boundaries. We can identify the number of people, where police stations are, hospitals, fire stations, infrastructure such as major roads, pipelines, railroads, different transportation networks, business data, employees and the sales volume which will help us better assess the economic impact of the next eruption.

Knowing the number and distribution of societal assets within hazard zones will help officials better prepare response strategies and it will help communities prepare for and recover from future volcanic eruptions.
