My working life is not all about seeing donkeys on my way between my home and my office. Sometimes (yesterday) you get to visit someone else's campus and see what large mammals they have kicking around (JPL, mule deer)!

Heading into work after a couple of Zoom meetings that I took at home, I was so lost in my thoughts that I nearly missed five donkeys seeking shade under a tree (and six more in the street)!

This is all awesome, not least because one of the interviewees is Emily Brodsky (pictured), and the last conversation I had with her was at about 2 am on Monday night, staggering back after the SCEC karaoke, on whether she would sing next year (unlikely) and what (maybe Bob Dylan, still unlikely).

In Palm Springs for the SCEC annual meeting, and once again I am seeing pictures of me on the screen (e.g. from Roland Bürgmann's keynote talk). Apparently I like to stand next to Roger Bilham

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.

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.

Morgan Moschetti @morganmp.bsky.social · 25/06/2026
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.

Gareth Funning @gfun.earth · 25/06/2026
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.
A noisy interferogram of the 2026 Venezuela earthquakes. The fringe gradient is highest by the coast, and dies away to the south.

Gareth Funning @gfun.earth · 25/06/2026
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.
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.
