"California's Active Volcano: Is an Eruption Imminent?"

The Long Valley Caldera in California, classified as one of the state's riskiest volcanoes, has been experiencing geological changes and seismic activity, raising concerns about a possible eruption. However, researchers from Caltech have concluded that while the increased seismic activity and ground deformation are significant, they are likely caused by the cooling and solidifying magma releasing gas and liquid, rather than a precursor to a supervolcanic eruption. Although the risk of a major eruption is low, the area still poses a threat and remains capable of powerful earthquake swarms. Other volcanoes in California, such as Mt. Shasta and Lassen Volcanic Center, also have cooling magma and show signs of decreased activity.
