"California's Cooling Supervolcano: Quake Threat Remains"
Researchers at Caltech have used distributed acoustic sensing (DAS) to create high-resolution underground images of California's Long Valley Caldera, a region characterized by swarms of earthquakes and ground inflation. The images reveal that the recent seismic activity is a result of the area cooling off and settling down, releasing fluids and gases. While the region is not believed to be gearing up for another supervolcanic eruption, the cooling process may still cause earthquakes and small eruptions. The study provides valuable insights into crustal dynamics and demonstrates the potential of DAS technology for understanding subsurface environments.
