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 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.

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, July 31, 2020, 11:54 AM PDT (Friday, July 31, 2020, 18:54 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 Hood over the last week, consistent with normal background seismicity. All other volcanoes are at background levels of seismicity. At Newberry volcano, starting on the July 4 weekend, several campers and US Forest Service (USFS) personnel have reported occasional strong sulfur smells in the East Lake and Cinder Hill campgrounds located on the east shore of East Lake inside the Newberry caldera. In response to these reports, USGS staff from the Cascades and California Volcano Observatories worked with USFS personnel to make gas measurements over the last week in areas of East Lake with known persistent gas features, as well as in the locations where sulfur smells were reported. Field crews found no unusual gas emissions. Field crews also noted that conditions were very dry inside the caldera and that lake levels were lower than they've been in many years, exposing several gas vents that are normally covered by lake water. Combined with the continued background levels of seismicity at Newberry, the field observations indicate that the sulfur smells are likely the result of localized, intermittent gas releases and are not due to larger changes in the Newberry magmatic system. The most likely explanation for the reported strong sulfur smells is that the current dry conditions and low lake levels in the caldera are allowing hydrogen sulfide and other gases to reach the surface without first being filtered by lake and/or ground-water. The USGS and USFS will continue to monitor conditions in the caldera.


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.
