Subsurface & Surface Processes

Poster

Mount Saint Helens, probably the most famous volcano in the Cascade Volcanic Arc, is located in the southwestern part of Washington State, USA. Characterized by a 2 x 3.5 km horseshoe-shaped and north-facing crater, Mount Saint Helens hosts one of the last expanding glaciers in the Cascade Volcanic Arc. Primarily caused by geothermal activity, an extensive system of firn & glacier caves has...

Subsurface & Surface Processes

Poster

On 10th and 11th July 2015, two successive sequences of PDCs travelled down the south flank of Volcán de Colima. The PDCs buried (and partly destroyed) a monitoring station and its solar panels, so that the surviving parts (batteries and data logger) simply ran out of power the day after and could be recovered later. The solar charging unit contained a thermometer that measured ambient...

Poster

Long Valley Caldera (LVC, California) is well-known for its complex geophysical signals that result from an active magmatic system featuring recent episodic inflation, long-term tectonic motion, and associated seismicity. Located at the eastern edge of the Sierra Nevada block, this region is also influenced by hydrological forcing associated with large amounts of precipitation (average annual...
