Unrest continues at Mount Spurr, with numerous small, shallow volcanic earthquakes detected beneath the volcano over the past day. Currently, most of the them are occurring under the Crater Peak vent, with some also located under the summit of Mount Spurr. Clear views of the volcano showed no unusual activity over the past day.

Here is a page that summarizes the current status.

The above map shows the clustering of the earthquakes under the main summit and the vent area.

They had to shovel the snow away from the cameras a couple days ago to get this view, earlier today:

March 1st. Not as many earthquakes as recent days, but a couple of larger ones.

Volcanic unrest continues at Mount Spurr and is characterized by ongoing earthquake activity and surface deformation. This continues the trend seen in these monitoring parameters. Seismicity remains elevated, but there has been a slight decrease in seismic activity in the past few days. Over the past week, over 70 earthquakes were located, most of them under the Spurr summit, and a lesser number located under Crater Peak. Data from GNSS stations show that outward inflation continues at about the same rate as has been occurring since spring of 2024. No unusual activity was observed in satellite data. Steam emissions were observed in web camera views earlier in the week. The Spurr monitoring network is functioning well although the CKT web camera remains mostly obscured by snow and ice.
