"California's Risky Supervolcano: Increasing Quakes Spark Eruption Concerns"

Scientists at the California Institute of Technology (Caltech) have identified over 2,000 earthquakes in California's Long Valley Caldera, a dormant supervolcano that has the potential to bury Los Angeles in ash. The recent seismic activity is believed to be caused by the release of fluids and gases as the area cools down. While researchers do not believe another supervolcanic eruption is imminent, the cooling process could lead to small eruptions and earthquakes. The volcano's magma chamber is covered by a hardened lid of crystallized rock, and although the caldera holds 240 cubic miles of magma, the risk of eruption remains uncertain.
