"Experts Sound Alarm as US Supervolcano Shows Signs of Imminent Eruption"
Geologists are concerned that the Long Valley supervolcano in California may be showing signs of an imminent eruption. Recent studies have identified over 2,000 earthquakes in the caldera, with evidence of fluids and gases being released as the area cools. While experts believe a supervolcanic eruption is unlikely, the cooling process could still cause earthquakes and small eruptions. Smoke billowing out from beneath the ground and a "resurgent dome" deep below the surface have also been observed, indicating volcanic activity. Although the last super eruption occurred 767,000 years ago, an eruption at Long Valley could pose a significant threat to the millions of people living in the area.
