Nearly 300,000 Americans remain on alert as Mount Spurr continues to show signs of volcanic unrest that began earlier this year.

While seismic activity is still elevated, the Alaska Volcano Observatory (AVO) said Thursday that it detected 60 to 80 earthquakes per week under Mount Spurr in the last month, a rate lower than in January and February.

‘The rate of deep earthquakes—occurring more than 6 miles below sea level—has remained relatively steady, indicating that magma is still active deep beneath the volcano,’ the AVO reported.

Ground deformation, a sign of magma movement, has slowed over the past three weeks. Volcanic gas measurements have not been possible since March due to persistent poor weather that has prevented monitoring flights.

‘The modest changes in monitoring data over the past month suggest the likelihood of an eruption has decreased,’ AVO noted, adding that the lack of recent gas measurements has made it more difficult to fully assess the volcano’s current state.
