Seasonal changes are mostly driven by the hydrological cycle. However, we noticed a clear difference between the volcano and the nearby valley, which we believe is caused by surface freezing at higher elevations during winter that inhibits recharge. (4/5)

Between 2013 and 2018, we observed elevated seismicity below the volcano, lower velocities at greater depths, and then a period of quiescence with increasing velocities. From these observations, we infer a change in recharge behaviour. (3/5)

We found that seismic velocity around the volcano increased significantly at the start of the 2004-2008 eruption period, along with surface deflation measured by GNSS. (2/5)

Excited to announce that our article on seismic velocity changes at Mount St. Helens is now freely accessible, following the embargo period. (1/5 - see further details in comments)

Our paper describing SeisMIC - a software suite for ambient noise monitoring was just published in @weareseismica.bsky.social, head there if you're interested or diving into velocity change monitoring using ambient noise yourself.

Only 6 days until submission deadline for #EGU24.
If you are working with ambient seismic noise or seismic interferometry , join us for session SM 5.2 "Ambient Seismic Noise and Seismic Interferometry ". Excited for all the new science!

I am currently en route to #AGU23 where I will be presenting our work concerning ambient noise interferometry at Mount St Helens. If you are interested in spatial imaging of velocity changes with variable data quality hit me up at S23D-0400 or send me a DM, so we can meet there. Hi Bluesky btw 🙂
