The Trump administration is in the process of closing at least two federal buildings used to monitor volcanoes in Alaska and Hawaii. The scientists and equipment in these offices provide critical information about possible eruptions, as well as the release of ash that could interrupt aviation.

During overflights on March 7 and 11, AVO measured significantly elevated volcanic gas emissions from Mount Spurr volcano. Newly reactivated fumaroles (gas vents) were also seen at the volcano's Crater Peak vent. Elevated earthquake activity and ground deformation continue.

The increase in gas emissions confirms that new magma has intruded into the Earth's crust beneath the volcano and indicates that an eruption is likely, but not certain, to occur within the next few weeks or months.
