CASCADES VOLCANO OBSERVATORY

CASCADE RANGE VOLCANOES
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN
Activity Update: All volcanoes in the Cascade Range of Oregon and Washington are at normal background levels of seismicity. These include Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams in Washington State; and Mount Hood, Mount Jefferson, Three Sisters, Newberry, and Crater Lake in Oregon.
Recent observations: Seismometers recorded a few small earthquakes at Mount St. Helens this week. More notably, four earthquakes were detected within 10 km of Glacier Peak, including events with magnitudes 3.5 and 3.1. Earthquakes occur sparsely at Glacier Peak, with only a handful in the previous 20 years—a reminder that the geologic timescale needed to develop a representative catalog of seismicity at some quiescent volcanoes is longer than the few short decades of seismic instrumentation in the Pacific Northwest.

Mount St. Helens VolcanoCam
This is a static image of Mount St. Helens, taken from the Johnston Ridge Observatory.
The Observatory and VolcanoCam are located at an elevation of approximately 4,500 feet,
about five miles from the volcano.
You are looking approximately south-southeast across the North Fork Toutle River Valley.
The VolcanoCam image automatically updates approximately every five minutes.
