volcanoes, earthquakes
and the hydrosphere through geodesy

With the help of AI coding assistance, I revived CrusDe (github). This has been out of commission for 10+ years now, after I could not keep up updating the code to work with upgrades to the libaries we use (Qt, xerces, etc.). The testcases all work, and I have confidence that I might find inspiration to tackle some long desired upgrades.

We're excited to welcome Karen Williams to the lab! She's starting as a post-doc with us to work on developing finite element stress change models for the Aleutian megathrust following the 2021 M8.2 Chignik and 2020 M7.6 Simeonof earthquakes. Karen got her Ph.D. at Virginia Tech and has worked on geodetic measurements and geodynamic modeling of vertical land motions in Chesapeake Bay. Welcome!

Darren Tan's paper on Vent-specific unrest at Pavlof Volcano, Alaska: Insights from multidisciplinary data was published in JVGR! It includes a broad synthesis of available geophysical, petrologic, and satellite-based thermal and gas data.

DOCTOR(!) Emily Graves passed her Ph.D. defense! Congratulations!

Zechao Zhou's (MSU) paper on The First Three Months of Postseismic Deformation of the 29 July 2021 Mw 8.2 Chignik Earthquake Provides New Constraints on the Down-Dip Extent of Coseismic Slip was published in JGR Solid Earth! We revise the 2021 M8.2 Chignik earthquake co-seismic slip distribution using early postseismic deformation, yielding a more compact co-seismic slip region with a much steeper down-dip gradient.
