It's that time of year again - the EarthScope ISCE+ course in InSAR processing and analysis is underway! Here (on his short course debut) is Francisco Delgado leading us through a first modeling exercise using InSAR displacements over Okmok Volcano!

We just got in from running errands, and this chap marches up to me as if demanding nose scritches (happily administered) and then settled in to munch on some of the excess grass outside our house.
If a good day is a day when I have seen a donkey, today is a day when I saw at least seventeen

It's that time of year! Please consider submitting to AGU session G024: Transient Deformation and Creep Processes in the Earthquake Cycle! Studies using geodetic, seismic, geologic and/or experimental data are all welcome, as well as numerical and analytical models. agu.confex.com/agu/agu26/pr...
Transient Deformation and Creep Processes in the Earthquake Cycle
Transient deformation and aseismic slip processes play a fundamental role in the earthquake cycle, yet their spatiotemporal characteristics and underlying physics remain incompletely understood. Advan...

The data firehose has been turned on! Have fun, InSAR-mavens!
NISAR global L-band provisional data products are now released in the NASA EarthData repository, accessible from the ASF and EarthData search. NISAR L-band data acquired on June 17, 2026 and later available as level 0 through level 2 and level 3 products. nisar-docs.asf.alaska.edu/availability...
Excited to share that our paper with @gfun.earth is now published! We investigate how probabilistic interseismic locking models relate to megathrust earthquake rupture, using the 2025 Mw 8.8 Kamchatka earthquake as a case study. agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Linking Interseismic Locking to Coseismic Rupture: The 2025 M<sub>w</sub> 8.8 Kamchatka Earthquake
A probabilistic locking approach identifies persistent asperities that control where large earthquakes nucleate and rupture A fully data-driven method infers locking patterns without prescribing ...

I made this because as far as I can see nobody else has?
Got my comment in today, opposing the proposed rule change that would politicize the award of scientific funding and place many obstructions in the way of scientists for no good reason. It is the last day. If you haven't done it already, please write something: www.regulations.gov/commenton/OM...

My summary of OMB's proposed Federal Financial Assistance rule was based on 22 years as an NIH Program Official and the damage I saw to science funding would be. I want to widen the lens now: scientists are not the only ones who should be alarmed. elizabethginexi.substack.com/p/this-new-o...
Under a Binface government, anyone who doesn’t accept human-made climate change as fact will be sent back to school, from Year 1 right the way to A Levels, to see if anything goes in the second time round. #VoteBinface
Come on Clacton, you have the chance to do the funniest thing
NEW - Greens won’t stand in Clacton. So it is Nigel Farage versus Count Binface.
I can report that Woking town centre was surprisingly lively at 4 in the morning, due to some liberal extension of the normal licensing laws and the explosive decompression following one of the most stressful England victories in my lifetime. Also, it's getting light outside.
Composite plot of the two coseismic interferograms (Sentinel-1, from Copernicus) with the USGS epicenters of the two earthquakes and faults from GEM. The shoreline San Sebastián fault lines up with the fringes in the west and is probably the fault responsible.
Not plotted here but the epicenter is located near the western limit of InSAR fringe, indicating rupture was predominantly towards the east, including Caracas. So rupture directivity, which is like a seismic Doppler effect, likely contributed to stronger ground-shaking effects and damage.
It's taken me a while, but here is my first interferogram of the Venezuela earthquakes from Sentinel-1. It's an ascending track to the west of the epicenter, and the pattern of displacements is consistent with slip on a fault that runs close to and parallel to the coast.
Another interferogram (Sentinel-1, descending track) covering the bulk of the rupture. The fact that you see essentially (the southern) half of the displacement pattern, indicates that the fault was offshore, or close to it. The noisiness is due to the tropical vegetation in-region.

I am currently in Budapest, where I don't have an earthly about what the talking heads on their World Cup coverage are saying. I don't miss the loudmouthed prat on FOX at all (yeah, you know which one). www.theguardian.com/football/202...

Fox’s broadcast at the tournament has become a story of two contrasting styles. And there is one clear winner

Went to the salt mines outside of Kraków yesterday and thought I'd model good technique
FRINGE 2026, day 2: Still zombified by jetlag, shotgunning coffee to stay conscious. Also, through some kind of black magic, someone has cut the auditorium in half, which is not doing wonders for my grasp on reality! We're starting with ESA future mission concepts this morning...
FRINGE 2026 is go! The premier scientific workshop for InSAR methods, results and science. Apparently they are not sure whether it is the 13th or 14th edition. But I have been coming to them since 2003 (as has Marcus Engdahl who made this slide) and wow I'm old!
Saw the first post-Mindanao earthquake Sentinel-1 data were available, and thought fuck it, I'll stay up late and process it. And actually, it's way more coherent than I thought it would be! And there are fringes!
Earthquake response: drop to a crouch for a second, then move to computer and spend three minutes refreshing the USGS webpage until a dot shows up on the map. (M3.4, Reche Canyon, near the San Jacinto fault)
Applications are now open (due July 1st) for the EarthScope ISCE+ course in InSAR processing and analysis! Alongside the usual background, theory and practical applications, we plan to cover some ISCE3 and NISAR content for the first time! www.earthscope.org/event/2026-t...
2026 Technical Course: InSAR Processing and Analysis (ISCE+) | EarthScope Consortium

It is important to validate InSAR time series results! And to call it out when people oversell the capabilities of the method! (Ideally before Science magazine airs out your dirty laundry in public...)
My latest for @science.org: Radar maps of sinking coastlines produced using InSAR can show dramatically different, even constrasting, results. Before this work makes its way to guiding efforts in the real world, a hard look is needed, researchers say.
First time at the Bowl for 2026! In the cheapest of the cheap seats. Alison Moyet is down there somewhere. (Loved all the Yazoo songs!) Marc Almond and the Human League to follow.
