LATEST UPDATES AND SITE NEWS:
August 5, 2019 Tahoma Creek Debris Flow
Posted on Wed, Aug 14, 2019, 17:00 by Scott Beason. Updated on Wed, Aug 14, 2019, 17:00

The 32nd recorded debris flow in Tahoma Creek occurred on August 5, 2019, between 6:44 PM PDT (8/6/2019 01:55 UTC) - 8:10 PM PDT (8/6/2019 03:10 UTC), as observed on the Pacific Northwest Seismic Network's (PNSN) Emerald Ridge (RER) seismograph. The event began as a sudden and significant change in the primary outlet stream from the terminus of the South Tahoma Glacier. This change caused a surge of water to go over loose, steep and unconsolidated sediment-rich areas just downstream of the terminus. Debris flow deposits were observed approximately 4 miles downstream at the Tahoma Creek Trail trailhead (an area affectionally known in the park as 'barrel curve'). The event is still being investigated... a good photo set (with a few videos) is available here: https://www.flickr.com/photos/mountrainiernps/sets/72157710161403356/. If you would like to view more information about the event, click here: http://www.morageology.com/geoEvent.php#145. If you were in the area of the South Tahoma Glacier or Tahoma Creek on the evening of August 5 and/or morning of August 6, and have any interesting observations, please send them to Scott Beason.

New Camp Schurman weather station added!

A new weather station has been added to morageology.com. Click the following link to see hourly data from Camp Schurman on the NE side of Mount Rainier's volcanic edifice at 9,500 feet: http://waterdata.morageology.com/station.php?g=MORAWXCS.

Longmire RSAM Down
Posted on Wed, Jul 10, 2019, 05:00 by Scott Beason. Updated on Wed, Jul 10, 2019, 05:00

The Longmire (LON) seismograph has been reporting ground vibrations from a construction project in the area near the seismograph. In order to prevent erroneous debris flow alerts, the RSAM (debris flow detection) analysis has been disabled. The system will be restored once the construction project has been completed.

CASCADES VOLCANO OBSERVATORY WEEKLY UPDATE
U.S. Geological Survey
Friday, October 22, 2021, 12:00 PM PDT (Friday, October 22, 2021, 19:00 UTC)


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 activity. 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: Earthquakes were located at Mount Rainier, Mount St. Helens, and Mount Hood this past week, consistent with background seismicity levels at each volcano. At Mount Hood a small swarm of earthquakes occurred between October 17-19, with earthquakes located under the summit (a common location for Mount Hood earthquakes). The Pacific Northwest Seismic Network (PNSN) located a total of 37 earthquakes during that time window, with depths ranging from 3-6 km (2-4 miles) below the surface. Most earthquakes had magnitudes below 1, with the largest being a magnitude of 2.5. Such swarms are not unusual at Mount Hood and are viewed by CVO and the PNSN as part of normal background seismicity at the volcano.


The U.S. Geological Survey and Pacific Northwest Seismic Network (PNSN) continue to monitor these volcanoes closely and will issue additional updates and changes in alert level as warranted.
