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.
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.
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.
@Craig_Craker @MtRainierWatch Do you have a precise time for this photo? There is an avalanche captured off of sunset amphitheater that Iโd 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. https://t.co/uYQvLrRBq4
Cascade Range volcanoes at normal background levels of activity this week, https://t.co/DSF2QB5ekz. #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. https://t.co/b6QAyopHNm
