A magnitude 4.6 earthquake struck just miles from Mount Spurr, an Alaskan volcano already showing signs of unrest, prompting concerns that an eruption could be imminent.<\/p>\n
The quake was recorded by the US Geological Survey around 10:38 a.m. local time near Petersville, about 86 miles from Mount Spurr and 34 miles north of Skwentna. The Alaska Earthquake Center confirmed the depth at 52.4 miles, with tremors felt as far away as Anchorage and the Mat-Su region.<\/p>\n
Mount Spurr has been under \u201cAdvisory\u201d status due to low-level seismic activity for months, with scientists tracking occasional small earthquakes beneath its summit. Back in March, it was briefly placed on \u201cWatch\u201d status amid fears it could erupt at any moment.<\/p>\n
Studies, including one published in Nature, show that nearby earthquakes can trigger volcanic eruptions, especially when magma pressure and underground gases are already elevated \u2014 conditions that exist at Mount Spurr.<\/p>\n
\u201cFluctuations in unrest are common at volcanoes,\u201d the Alaska Volcano Observatory stated, \u201cand eruptive activity remains possible, though unlikely.\u201d However, similar patterns of slowing and surging unrest preceded the volcano\u2019s last eruption in 1992.<\/p>\n
If an eruption does occur, experts predict it would most likely happen at Crater Peak, one of Mount Spurr\u2019s side vents. The resulting explosion could spew ash clouds up to 50,000 feet into the sky, possibly blanketing Anchorage with debris and triggering mudslides and fast-moving avalanches.<\/p>\n
The Broad Pass Thrust Fault, which runs through the region, is considered active and capable of producing magnitude 7.6 to 7.8 earthquakes, amplifying seismic risk.<\/p>\n
As of now, Mount Spurr remains under close watch. Residents across Alaska are urged to stay informed and follow updates from USGS and AVO as the situation evolves.<\/p>\n","protected":false},"excerpt":{"rendered":"
