A magnitude 3.7 earthquake struck Alaska today, just 30 miles from Mount Spurr volcano, which is showing signs of reawakening. Scientists with the Alaska Volcano Observatory (AVO) have warned that an eruption could occur within weeks or months.
Mount Spurr, 80 miles from Anchorage, has recorded hundreds of small tremors, increased gas emissions and deformations of the ground surface. Seismologists have noticed a significant increase in seismic activity since April, with the weekly average of tremors increasing from 30 to 125 by early October, writes A2 CNN.
Officials in Anchorage have raised the emergency level to level two, preparing the city for a possible eruption. According to experts, the eruption is likely to occur in the side crater Crater Peak and will be powerful, sending ash clouds up to 15 kilometers into the air. Such a scenario could cover Anchorage with a layer of volcanic ash, causing problems for public health and air transportation.
Mount Spurr's last eruption occurred in 1992, darkening the sky and forcing the airport to close for 20 hours. Scientists are closely monitoring the situation, noting that a volcanic earthquake would be the last sign before an eruption. (A2 Televizion)
