Regional geoelectric hazard assessment

Regional geoelectric hazard assessment

Geomagnetic storms can wreck havoc on the world’s electrical grids, communications systems, and navigational infrastructure. To prepare for future geomagnetic storms, scientists need to know more about Earth's geoelectric field and how it varies during storm events.
Seismicity beneath Kīlauea ‘s Southwest Rift Zone

Seismicity beneath Kīlauea ‘s Southwest Rift Zone

Researchers are examining seismic activity within Kīlauea ‘s rift zones to understand the connection between the caldera and the rift zones to provide a better framework for interpreting seismicity around the volcano.
Antarctic Ice Shelf ‘Sings’

Antarctic Ice Shelf ‘Sings’

According to research led by Colorado State University, winds blowing across snow dunes on Antarctica’s Ross Ice Shelf cause the massive ice slab’s surface to vibrate, producing a near-constant set of seismic tones that could potentially be used to monitor changes in the ice shelf.
