📢 New paper out today in Earth Observation When two InSAR products disagree, does that mean InSAR is unreliable? Not necessarily. We show how spatial resolution, temporal mismatch, validation-network design, and uncertainty can strongly affect conclusions. 📄 Open access: doi.org/10.5194/eo-1...

Comment on: “Evaluating InSAR-derived rates of surface-elevation change along the central U.S. Gulf Coast” by Li et al. (2026)

Abstract. Li et al. (2026) compare two InSAR-derived surface-elevation change datasets, reported by Ohenhen et al. (2024; hereafter O24) and Wang et al. (2024; hereafter W24) for the central U.S. Gulf...

There are other technical disputes that are beyond the focus of the story. The essential story has not changed, but this debate will continue to play out in the literature. (And a hopefully even more robust discipline will emerge from it!) Here's their comment:

Imagine your city slowly sinking. In India’s megacities, 80M+ people face this reality. New satellite radar research by @nitheshnirmal.bsky.social reveals where the ground is shifting most unevenly. 🌍🏠 #LandSubsidence www.nature.com/articles/s41... @shirzaei.bsky.social @vtgeosciences.bsky.social

*** Research Spotlight *** #Hydropower #Dam Safety Matters. Mohammad a postdoc at @EOI_lab of uses #InSAR data to detect subtle #deformation of hydropower dams, quantifying #damage risks. Here, he shows deformation of #RoanokeRapids Dam. Keep up the good work! @unuinweh.bsky.social

When Fragility Turns Disaster into Catastrophe Dr. Manoochehr Shirzaei underscores lessons from Afghanistan’s Aug 31 quake: fragile infrastructure & weak preparedness can turn disaster into catastrophe. Incident Brief: unu.edu/inweh/news/a... #AfghanistanEarthquake @shirzaei.bsky.social

*** Research Highlight *** Ibrahim is a first-year PhD student in @EOI_lab, and his research focuses on #LandSubsidence #hazards and #risks to critical #infrastructure, integrating cutting-edge techniques in #remotesensing, #ML, and physical #modeling. He enjoys playing #soccer. Well done!

*** CONGRATULATIONS *** I am thrilled to announce Florence Onyike, a graduate student at @EOI_lab and @HIRSlab, has received the American Water Works Association (@awwa) scholarship for research on #managed #aquifer #recharge. Many congratulations, Florence! @unuinweh.bsky.social

*** WELCOME TO FALL 2025 *** I am thrilled to welcome you all to the #Fall2025 semester. I wish a productive and fun semester for our team at @EOI_lab and @HIRSlab labs of @vtgeosciences @VT_Science @UNUINWEH .

*** congratulations***

**** Media Coverage **** I had the opportunity of being on national TV, @cbsnews.com , yesterday discussing our recent publication on the #US #sinking #cities. Pub: www.nature.com/articles/s44... CBS news piece: youtu.be/hXznyppIwz0

**** NEW PAPER ALERT **** Just published in @nature.com Cities, led by Dr. Ohenhen and in collaboration with two generations of researchers from @EOI_lab and @HIRSlab of @VT_Science, we map #sinkingland at 28 major #US cities. Congratulations, Leonard and team! Link: www.nature.com/articles/s44...

*** Welcome to EGU 2025 *** I wish you all a successful #EGU25 . Please consider attending the following presentations by @EOI_lab and @HIRSlab members and collaborators.

*** Happy Earth Day *** Wishing you a Happy #EarthDay! Let's #nurture #nature for a better #future. “To leave the world better than you found it, sometimes you have to pick up other people’s trash.” —Bill Nye

*** Congratulations*** Please join me in congratulating Dr. Mohammad Khorrami (@Khorrami93) on successfully passing his thesis defense! This is a tremendous achievement, and we are all proud of his hard work and dedication.

***** EVENT UPDATE **** On April 8, 2025, the roof of #jetsetnightclub in #SantoDomingo collapsed during a live show, claiming at least 221 lives. Using #satellite data, @EOI lab detected #settlement of –2 mm/yr, which accelerated in mid-2024—an early warning sign of structural failure. eoivt.com

***** Public Lecture ***** Dr. Ohenhen and I will give a lecture on #sinking #cities at the American Museum of Natural History (@AMNH). Please join us! Time: April 2, 7 pm EST. Link: www.amnh.org/calendar/sin...

Nowruz Mubarak! May the spirit of renewal and growth bring you peace and happiness in the year ahead 🎉🎉🎉
