Got lucky with a tight weather window yesterday at Mount St Helens to collect some temporary infrasound sensors. Today there a foot of snow in this spot.

Great day of fieldwork at Mount St. Helens putting out sensors to track early season debris flows. Love this time of year on the volcano.

Nice day up on Rainier deploying infrasound. Lots of snow at the site. Be back in a month!

Finally got the last two infrasound sensors that were buried this winter from Mount Hood Meadows. One was still in the tree we strapped it in, one was...not. At least they set it down nicely.

What are the odds of a clear enough sky to see the lunar eclipse early tomorrow morning in the Portland area? #askingForMyKids @NWSPortland

Infrasound recordings of the @SpaceX rocket booster breaking up from arrays on Adams, Mount St. Helens and Rainier. Also recorded on seismometers but only as air-coupled ground waves.

Sorry, ground coupled air waves. Don’t tweet before bed.

Great day for a card swap at Mount Hood!

A tectonic earthquake swarm is ongoing at Mount Hood, no sign of changes in volcanic activity. >100 earthquakes south of the summit in an location where swarms commonly occur. Maximum magnitude M2.7 & depth ~5km (3mi). @PNSN1 & #CVO monitoring closely. ow.ly/25Sq50DaWAz

Cascade Range volcanoes at normal background levels of activity this week, ow.ly/p83F50CPQTg. #CVO field team skis out to monitoring station HIYU, NW of #MountHood (6km), to troubleshoot a communications issue and conduct station maintenance. #VolcanoUpdate

"One of the strangest #seismic signals we've ever seen" has been occurring at #MaunaKea #Volcano in #Hawaii for decades. USGS scientists think it has everything to do with #magma but nothing to do with the volcano building toward eruption. ow.ly/34v550zHGBi

Long-dormant volcano Mauna Kea has been quietly grumbling for decades

Small, periodic earthquakes have happened every seven to 12 minutes for decades, but aren’t reason for alarm, a new study finds.

Honestly the strangest swarm of earthquakes I've ever had a chance to study: sciencenews.org/article/maun… science.sciencemag.org/conte…

#shareEGU20_ThatsMySignal I'd like to share seismic signals and obtained tilt signals of a #debrisflow at #Illgraben, Switzerland @WSL_research. And I nominate @stefdonner @InSeismoland @seismotologist to share their signals :-)

During April 12-13, Mount Hood's monitoring network detected a burst of ~100 small earthquakes at depths 1.8-4.3 mi below sea level. EQs are associated with regional tectonic faulting & not volcanic activity. Mount Hood at background levels of activity. ow.ly/mTza50ze6vK

#CascadesVolcanoObservatory Scientist-in-Charge Seth Moran was interviewed for this @nytimes articles that discusses the challenges we face in monitoring high-threat #volcanoes. nytimes.com/2019/09/09/scien…

We’re Barely Listening to the U.S.’s Most Dangerous Volcanoes (Published 2019)

A thicket of red tape and regulations have made it difficult for volcanologists to build monitoring stations along Mount Hood and other active volcanoes.

An update on this rock avalanche that was well-recorded by seismometers across southwest British Columbia...

On Monday morning at 07:41 am local time, a significant rock avalanche occurred at Joffre Peak in British Columbia in Canada, running out over a distance of about 4.5 km:- blogs.agu.org/landslideblog/…

My #hoodtocoast2018 team was 12th out of 1032 teams & the top women’s team overall. At the Awards Ceremony, the top walking, HS and men’s teams were awarded trophies. When we asked why women’s weren’t announced we were told by RD Bob Foote, “Go talk to someone who cares” WOW

Glacier Peak is considered a "very high threat" volcano by the U.S. Geological Survey. It sits less than 70 miles northeast of Seattle, and it needs more monitoring stations. st.news/2vVeFDu
