Volcanologists are sounding the alarm as three volcanoes in the United States show heightened signs of unrest. Alaska’s Great Sitkin and Mount Spurr, along with Hawaii’s Kilauea, have each experienced increasing seismic activity that could signal potential eruptions in the near future. The most concerning updates come from Great Sitkin, now at “Watch” status—the third tier in a four-level alert system—following several minor quakes and visible lava at the summit crater. Mount Spurr, which lies roughly 75 miles west of Anchorage, has seen a dramatic spike in earthquake activity. Back in April 2024, the region recorded about 30 small quakes per week; now that number has soared to approximately 125, suggesting a 50% chance of eruption. Meanwhile, Hawaii’s iconic Kilauea volcano erupted for the ninth time since December 2024 on February 11, shooting lava up to 300 feet into the air. Although no homes have been affected so far, authorities remain on edge about potential ash fallout and airborne volcanic glass.

This surge in seismic activity isn’t just random background noise—it’s the earth’s way of signaling internal shifts. Scientists report intensified earthquake swarms near each of the three volcanoes, which typically point to magma moving closer to the surface. These tremors are being tracked using advanced monitoring systems that also detect ground swelling and gas emissions—two more red flags for an impending eruption. When you combine all of these warning signs, it paints a concerning picture that these volcanoes could erupt with very little notice. Communities near these regions are being encouraged to stay vigilant, monitor emergency alerts, and have evacuation plans in place.
