Officials update threat level of massive volcano due to erupt as 300,000 Americans brace

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.
