ANCHORAGE, Alaska - Scientists at the Alaska Volcano Observatory are keeping a close eye on Mt. Spurr — USGS geophysicist Dave Schneider said activity for the volcano is still considered elevated above normal at code Yellow but has not increased significantly in the past week.
“The earthquake activity waxes and wanes on any particular day,” Schneider said. “But overall, it’s in a general sort of stable pattern.” The last time Spurr erupted was in 1992, Schneider said that followed an extended period of unrest that ramped up before the actual event. He said it’s likely that Spurr would give similar warning signs before an eruption occurred. “We think that sort of change would happen maybe days or weeks prior to an eruption. And that would allow us to shorten our time frame from when we expect activity to occur,” he said. Sophisticated software and regular overflights are helping scientists construct 3D computer models of the mountain, allowing them to see change over time. The images suggest the volcano is slowly heating up from within.“Even at that point it’s not certain an eruption will occur. There are lots of volcanoes that get almost all the way to an eruption and don’t, it doesn’t actually happen. So it is important for people to be aware this is not a certainty, but it’s more likely than not,” Schneider said. He said the observatory is coordinating with partners around the state to make sure that people are as prepared as they can be without panicking. “I think that’s a big thing to remember here,” he said. “Ash fall can be disruptive, but it is manageable.” He said right now AVO is in the “preparedness stage,” watching the volcano by day and ready to respond at night should activity pick up.Iditarod musher tried to press emergency beacon, but race officials say they didn’t receive signalPedestrian struck by vehicle in hit & run, Anchorage police have made an arrest

Mount Spurr in Alaska Shows Increased Volcanic Activity, Raising Eruption ConcernsMount Spurr, a volcano in Alaska rising over 11,000 feet, is showing signs of potential eruption with thousands of recent earthquakes. Experts estimate a 50/50 chance of an eruption, fueled by increased activity over the past 10 months. Located just 80 miles west of Anchorage, a city of nearly 300,000, the possibility of danger to life and property is a serious concern. The volcano's past eruptions have caused ash clouds that have enveloped Anchorage, leading to airport closures and millions of dollars in damage. Scientists are closely monitoring the situation, hoping for advance warning signs before a possible eruption.
