GeoGirls 2019 group photo, with Mount St. Helens in the background.

GeoGirls hike to Willow Creek, on Mount St. Helens’ Pumice Plain, to learn more about the ecology of the blast zone and how the area has recovered since the catastrophic May 18, 1980, eruption. Here, they look at stream characteristics and how it has influenced the return of life to the area.

The GeoGirls create field drawings of 1980 pyroclastic flow deposits on Mount St. Helens’ Pumice Plain.

GeoGirls venture into Ape Cave, a 2,000-year-old lava tube on the south flank of Mount St. Helens, as they learn about Mount St. Helens’ eruptive history and lava flows.

USGS scientists installed a thermal imaging camera on a current USGS streamgage on the Neversink River near Claryville, New York. This equipment will help monitor surface water temperatures and can help understand the amount of groundwater contributing to surface runoff.

This Coastal Change Storm Hazard Team map was created Friday, July 12, 2019 and shows forecast beach erosion (the strip of colored bars closest to the coast), overwash (middle strip) and inundation (outer strip) effects of Tropical Storm Barry’s predicted landfall in Louisiana.

Kate Scharer (USGS) provides CO CAPT Paul Dale (Navy) with the field mapping team’s initial product, showing the surface fault rupture at NAWSCL as well as the temporarily deployed seismic and GPS sensors that were rapidly deployed. Contributions of field data from within the base were from CGS & USGS, and from outside the base were from Univ.

Two portable sensors: a strong motion sensor (to record strong shaking that can be felt) and a broadband sensor (to record weak motion for detecting small earthquakes) buried into the ground to detect earthquakes. These stations can be quickly deployed and send real-time data back to the USGS via cellular telemetry immediately after they are installed.

Fault rupture crosses dirt road, with California Geologial Survey vehicles for scale. Displacement at this location is primarily normal (vertical). Photograph taken near the northern end of the rupture resulting from the M7.1 Searles Valley earthquake.
