An earthquake was detected just miles north of an Alaskan volcano showing signs of unrest and potential eruption.
The US Geological Survey reported a magnitude 4.6 quake near Petersville, about 86 miles from Mount Spurr.
The Alaska Earthquake Center said: 'We have reviewed a M4.6 earthquake that occurred at 10:38 a.m. local time, 52.4 miles deep and 34 miles north of Skwentna.'
'This event was felt throughout Anchorage and the Matanuska-Susitna region,' the center added. Anchorage sites are located more than 100 miles from the epicenter.
The USGS has received nearly 200 reports of shaking from the sparsely populated area.
Mount Spurr is currently under an 'Advisory' due to low-level unrest, with occasional small earthquakes detected beneath the volcano.
A 2021 study published in Nature found that most volcanoes, especially those already showing signs of unrest like Mount Spurr, can be triggered to erupt by nearby earthquakes.
The study notes that this is more likely when factors such as magma pressure and underground gas buildup are already present.
