What happened in spring 2025? (Nothing)
Mount Spurr is a volcano 78 miles northeast from Anchorage. You can see the peak from Anchorage on a clear day.
In early 2025, the Alaska Volcano Observatory noticed signs that this volcano could erupt.
WHY DID SCIENTISTS THINK MT SPURR MIGHT ERUPT?
Steam coming from the top
Small earthquakes around it
THEN WHAT?
More steam, more earthquakes, and other changes were expected before an eruption. The scientists told us we will have some warning.
Those other signs never happened. Scientists eventually lowered the warning and said it was no longer likely to erupt.
