@Zaffino @timberlinelodge Late to the game here, but it came with a nice signal on the seismic monitoring network (times are UTC (local+7))

BIG rock-slide on Mt Hood today, likely originating from the Steel Cliffs above White RIver Canyon. I put a 1 second pause between frames, so you can see the progress of the massive dust cloud. From our camera @timberlinelodge around 2:50 pm Oct 11 #kgwweather

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.

@MarianoRemirez @_VolcanicASH_ @InfraSaurus West side, not far from where the Loowit Trail comes out of the south fork Toutle.

@thelenwes @_VolcanicASH_ @InfraSaurus Woow! Fascinating! Is it the east side of the volcano?

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.

@USGSVolcanoes Heat maps 😍😍😍

#MountHood #earthquake density map (right) shows areas that have had the most earthquakes (blue = more, brown = less). Density map makes it easy to visualize a big dataset (EQs since 2010!) & understand it at a glance. Obvious visual cues show how the phenomenon is clustered.

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

What volcano in southern oregon is still dormant? This one 👇👇👇

If you want to know what my garage and bedroom look like, read on.

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

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.

Great day for a card swap at Mount Hood!

@Craig_Craker @MtRainierWatch Do you have a precise time for this photo? There is an avalanche captured off of sunset amphitheater that I’d like to look at on the monitoring network.

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

@autpops Great pic! Do you have a date and time? I’d like to see what the avalanche looked like on the monitoring network up there.

The night that I caught a massive avalanche on Tahoma 👀 Can you spot it?

"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

Honestly the strangest swarm of earthquakes I've ever had a chance to study: sciencenews.org/article/mauna-… science.sciencemag.org/content/368/64…
