The M 3.9 earthquake occurred at a depth of 2.7 miles below sea level. At this time, seismologists do not believe the earthquake swarm signifies a...

While most of the Cascade Range volcanoes are located in remote areas, volcanic processes like ashfall and lahars can put large populations at risk...

Burst-like swarms commonly interpreted to be caused by movement of hydrothermal fluids (water).

A CVO geophysicist discusses how the monitoring stations installed at Mount Hood in 2020 provide insight into the recent Mount Hood earthquake swarm.

An earthquake swarm at Mount Hood is ongoing. The earthquakes are associated with regional faulting and are not a sign of changes in volcanic activity...

These stations enhance the existing monitoring network at this high-threat volcano and improve the ability of CVO scientists and their partners to...

New sensor network will help safeguard lives and property, and because of the relatively small footprint, there will be very little disturbance to the...
