A major seismic event struck Venezuela yesterday, with magnitudes reported as Mw 7.2 and Mw 7.5 by the USGS. According to several seismologists, due to the complexity of the seismic signal, these may in fact represent a single earthquake event (earthquakeinsights.substack.com/p/catastroph...).

NASA-ISRO SAR (NISAR) satellite imaged Venezuela June 25. NISAR SAR interferometry (InSAR) enabled calculation of surface displacement. Displacements have red tones for east and blue tones for west, with white in middle near-zero over fault rupture. Fault ruptured far to east under ocean. #venezuela

Really interesting footage from Galfa, southern Trinidad, after the Venezuelan earthquake doublet: youtu.be/4M8UpZYz4ss?... ⚒️
1) significant uplift of a section of coast with lots of small faults
2) fascinating zone where boulders trapped sea life, now elevated

The A33 track, 2026-06-18 with 2026-06-25 , we see also the rupture along the Bocono fault , but with a lot of noise..

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.

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.

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.

Northwestern Venezuela was struck by several large earthquakes today and yesterday (M6.2, 5.8, 6.3). Why did these shallow thrust events occur in an area where previously only strike-slip earthquakes have been documented? We speculate about the geology in our latest post.

This is fantastic news!
OpenTopography is excited to announce a major expansion to its international data catalog with the addition of the High Resolution Digital Elevation Model from Natural Resources Canada. This 1-meter resolution dataset is ideal for a wide range of applications.
