Faculty at UCR! Earthquakes! Fault creep! InSAR! GNSS! Seismology! He/him! Executive Editor at @weareseismica.bsky.social! Yes!

A noisy interferogram of the 2026 Venezuela earthquakes. The fringe gradient is highest by the coast, and dies away to the south.
Interferogram of the earthquakes in Venezuela. Shows the western extent of the rupture, and that the earthquake was likely on an E-W striking fault.
Me licking the wall of the salt mine. Conclusion: salty
Slide describing the Geostationary Synthetic Aperture Radar concept as proposed in the Hydroterra+ concept
Slide showing the Harmony observation concept for measuring stereo phase
Slide showing the Copernicus SAR 'System of Systems' concept with Sentinel-1 First Generation, ROSE-L and Sentinel-1 Next Generation, and their respective imaging capabilities
Slide on the mission requirements and application needs of ROSE-L.
The auditorium at Jagellonian University, yesterday
Maps of InSAR velocities in the Laguna Salada area in Mexico – good pixels show positive range change (subsidence). Bad pixels show uplift! The modal difference is 2 mm/yr of uplift!
Persistent scatterers found using conventional fixed polarization InSAR over a rail line
Along-track displacements of the 2025 M7.8 Myanmar earthquake using the expanded burst overlap method – a pretty clear picture of the displacement field!
Test of the Instantaneous State InSAR (ISI) approach versus the post-event, batch style processing for a subsiding site in Amsterdam. If anything, the ISI time series agrees with the data better of the two
Recent InSAR data from the Evans Ice Stream in West Antarctica. From left to right: A 6-day interferogram (S1C to S1A), which has so many fringes on the ice stream, it is decorrelated. Then a 1-day interferogram – you can identify all the fringes on the ice stream! Then the difference between two 1-day interferograms one month apart – you can see differences in the ice flow speed and the location of the grounding line!
Results of along-track interferometry over the Agulhas Current in the Indian Ocean (off the SE coast of Africa) using Sentinel-1C with a modified data acquisition mode. Shown (from left to right) are the SLC, the coherence, the along-track interferometry (ATI) results from Sentinel-1C and a similar ATI result made from Radarsat-2 data, ten minutes later.
Details of Sentinel-1 EW (extra wide) mode interferometry. It was a successful demonstration, and it is not clear whether there are any plans to produce the SLC images you need to do this routinely. But they could!
Diagrams showing the current changes to the Sentinel-1 constellation. Left: the configuration from January to June 2026, with three satellites (S1A, S1C and S1D). Middle: the proposed movement of S1C. Right: the goal end state with just S1C and S1D, six days apart in orbit.
Slide showing images and logos for all of the FRINGE workshops since 2003. The interferogram of the Bam earthquake seems to appear on a lot of them.

A concert is happening in the main square of the Old Town in Kraków, a big stage, screens, cameras, the works
Sentinel-1 interferogram of the 2026 Mindanao earthquake. Pink box shows location of the zoomed in version
Map of the Riverside-Moreno Valley-Redlands area, with the epicenter of the recent M3.4 earthquake marked on as a red dot
The stage at the Hollywood Bowl with the Hollywood sign behind in the distance
Shadow puppets on screen (right – Bimo encountering an ogre, I think) and Julian Lozos (lower left) playing as part of the Gamelan ensemble
Welcome to Arizona sign at the Utah-Arizona border, with an overheating pickup truck parked in front of it

View from I-70 of a canyon – crags either side of a river
Sign that says "Welcome to colorful Colorado" taken from the window of the van. We are not in Kansas anymore.
Signs in the hallway of Monroe Elementary School in Topeka, KS, where the Brown v Board of Education lawsuit arose – on the left "White", on the right "Colored", back from when the school was segregated. It is now a National Historic Site.
A bright and colorful mural at the Brown v Board of Education National Historical Park. Amongst other things, the text says "We are one" and "We ❤️ Topeka" along with a picture of the school at the site and MLK and (?)Cesar Chavez.
Me holding a grande margarita glass which is as big as my head. Jen's more sensible regular version is in a terracotta jar saying "Columbia, MO", because that's where we are.
Jen and me in the cab of our Ford Transit van. Jen is grinning, I have my eyes closed for some reason.
A sign saying "YARN". We walked further down the road, but were unable to find any.
One blurry donkey in the dark
Earthquake waveform, looks like only one set of wiggles, only one earthquake
Map of the Riverside area with two red dots on it, signifying earthquake epicenters
'Black Tidal Wave'
Jen taking a selfie in front of a statue who might be taking a selfie? (No, she's looking at herself in a mirror.)
View from the window of the new Geffen Galleries at LACMA, showing the curved concrete structure of the building
View from the data output of the Raspberry Shake seismometer in my house from the recent earthquake. Top panel is the blown-up window of a few seconds either side of the earthquake, with a nice earthquake waveform with clear P- and S-wave arrivals shown. Bottom is the helicorder plot of the same thing, showing the earthquake waveform and also what looks like an aftershock a few minutes later.
Map of Riverside and Grand Terrace, with my location and the earthquake epicenter marked on it ("me" and "eq", respectively).
Karol G, grinning volubly, seen through a forest of raised hands and phones, somewhere near the end of her set. Maybe this was when they dumped the confetti on us?
Laufey (front, center) and her jazz ensemble
Aurora (right) and her backing vocalist (left) in matching white dresses and sleeve gauntlet things, singing during Tomora's set on the Gobi stage
Iggy Pop, topless as ever, and in something approaching his classic "mic stand" pose, performing on the Mojave stage with his band behind him.

David Byrne (holding a beige guitar in the center) and band, all in blue jumpsuits and carrying all their instruments, even the tricky ones (keyboards, drums) via harnesses.
3/5 of The Strokes. Julian (right) wore a dark trenchcoat that made it almost impossible to photograph him. Smart.
Geese in the Gobi tent. Chap on the left is the singer.
Ecca Vandal (left) with her drummer (right)
Kacey Musgraves in a cowboy hat, white top and jeans, holding a guitar and singing, in front of a horse trailer with a "KM" logo on the side. She had silver eye makeup in the shape of a star over her right eye.
Me dancing under the coloured shade streamer things at the Do Lab in pink skull hat, (mostly) yellow skull shirt and blue flaming skull shorts, rounded out with a bag with a skull in headphones on it.
Blood Orange played his set on a small stage on the middle of the Mojave tent. Made it really easy to get good photos of him!

Moby (left) watching agog as Jacob Lusk (front right) belts out 'Natural Blues'.
All three of the xx – from left to right, Jamie (doing percussive things and keyboards in the back), Oliver (temporarily eschewing bass to sing, crouching in the front), and Romy (serene as ever, on guitar).
