Excited to share the 2nd paper from Olivia Paschall's PhD work, where she demonstrates how adding cross-polarized SAR imagery to the normal co-polarized data can improve inferred deformation rates, applied to Death Valley: kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F...
🚨 New map redraws our understanding of how continents deform 🚨
We are excited to share ground-breaking work led by COMET Co-Director @timwrightleeds.bsky.social, published in @science.org. Read more: comet.nerc.ac.uk/new-map-redraws-our-understanding-of-how-continents-deform/

Permanent deformation of the Earth and its surface happens after *every* earthquake, no matter it's depth or distance.
This has been known to seismologists for decades, because we can see the permanent offset in our seismograms. With large earthquakes, even 100s of km will still cause mm of offset.
If you’re working on ground motion, hazards, or resilience—we’d love your contribution. Join us in Toronto!

Went out downtown tonight and got leathered with my friend Gordon. (No reason, except Friday.) On the way home, my Uber driver asked me lots of fun questions about earthquakes. And now I'm home and learning that NISAR successfully deployed its reflector?! What a great evening!
I did not have the opportunity to screengrab myself while I was talking earlier (super coherently, I'm sure) about the basics of geophysical modeling, but Franz did...

Screengrab from Zoom, on the left a slide about the relationship between surface topography and interferometric phase (the basis for topographic mapping using InSAR), the right a picture of the instructor, Ann Chen.
Here is Ann Chen on a deep dive into InSAR theory, explaining the basis of using InSAR in mapping topography. (Later she will talk about measuring deformation and the causes of decorrelation, all the good stuff!)
Screengrab of the Zoom from today's class. On the left is the output of a Jupyter notebook showing multiple plots of potential displacement of the volcano for different source locations. On the right is Franz Meyer, my co-instructor, who is leading this session.
It's Day 1 proper of this year's EarthScope #InSAR Processing and Analysis short course (the "ISCE+" course)! Here, Franz Meyer is leading participants through a simple Mogi source modeling exercise using InSAR data from Okmok volcano! Real data and real models on an interactive online platform!
Not only did I give a talk at IPGP, but they recorded it and recently uploaded it to YouTube! If you want to hear me talking about fault creep and the various approaches my group uses to study it, this video is for you!

Screen grab of a wrapped interferogram over southern Kamchatka
First Sentinel-1 interferogram from southern Kamchatka! Lots of what I am assuming are tropospheric signals (e.g. over the volcanoes), but I also see long-wavelength fringes that change in azimuth from the NE (~shore-perpendicular) to the SW (~shore-parallel). Optimistic it could be the earthquake!
In case you are free in the next few minutes:

First tutorial of day in ESA living planet 2025 #LPS25 on #hylite for hyperspectral mapping
Just arrived in Vienna for the ESA Living Planet Symposium after a difficult week shadowed by war. Grateful for the chance to unwind a bit and looking forward to reconnecting with friends and colleagues. 🌍✨ #ESALivingPlanet #Vienna #RemoteSensing
Congratulations to @kdevlin525.bsky.social on her newly-published (open access) article on the use of InSAR in active agricultural areas like California's Central Valley: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Properly staggering! 😮😱

Azimuth offsets of the Myanmar earthquake from Sentinel-1A and Sentinel-1C data. Positive displacements are in the line-of-sight (LOS) direction.
Range offsets of the Myanmar earthquake from Sentinel-1A and Sentinel-1C data. Positive displacements are in the line-of-sight (LOS) direction.
Sentinel-1C(!) acquired new SAR data over Myanmar yesterday. Here are the azimuth and range offsets. Not particularly unexpected (right-lateral slip, 400 km+ long rupture), given earlier InSAR/image offset results, but surprisingly clean, given S1C is not out of its commissioning phase.
Herkes nasıl da güzel döküldü buraya. Ben daha cool değilken gelmiştim hehe. Üşengeçlikten anlatacak pek bir şeyim yok şu ara ama @evrimagaci.org 'na her ay düzenli olarak ayın depremi yazısı yazıyorum. Oraya bir bakın.
