Reinterpreting the Recurrence Time–Moment Relation of Global Repeating Earthquakes: A Scattered Data Cloud Bounded by Crack‐Model Physics

Long-term quasi-periodic repeaters from latest global catalogs reveal a triangular data cloud rather than a simple power law The 1/3-slope lower bound reflects ruptures under long-term loading wh...

Dear colleagues, I would like to highlight an upcoming AGU26 late-breaking session, S030, focused on the recent 2026 Venezuela earthquake sequence: agu.confex.com/agu/agu26/pr... Please consider submitting an abstract and feel free to share this session with colleagues who may be interested.

The 2026 Venezuela Earthquake Sequence: Insights from Seismology and Beyond

In June 2026, a large, complex earthquake sequence struck north-central Venezuela along the boundary between the Caribbean and South American plates, a right-lateral strike-slip fault system that had ...

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

Map of north-central Venezuela with NISAR line-of-sight displacement map shown in false color varying from red to white to blue. Red land moved east (towards satellite) and blue land moved west. InSAR only measures land, so ocean and lakes have no measurements. Background map from Google satellite natural-color images on land and bathymetry in ocean.

I can see a fault bend/gap story emerging from the discussion I had with colleagues about why the USGS reports two events (M7.2 → M7.5). Maybe there is a fault bend or gap between the west rupture (M7.2) and the east rupture (M7.5)? Here is an iPad schematic:

First Sentinel-1 interferogram from southern Kamchatka! Lots of what I am assuming are tropospheric signals (e.g. over the volcanoes), but I also see long-wavelength fringes that change in azimuth from the NE (~shore-perpendicular) to the SW (~shore-parallel). Optimistic it could be the earthquake!

Quickly plot the rough location of the 2025 Mw8.8 Kamchatka earthquake (USGS hypocenter) on Figure 1 in Pinegina et al. (2018). I wonder if the 2025 event re-rupture the northern rupture of the 1952 Mw9.0 event? Also, did the 2025 event rupture across the "segment boundary" at ~N53? rdcu.be/eyrre

The whole #MyanmarEarthquake rupture in one interferogram! This is three consecutive wide swath frames of ALOS-2 data, provided by JAXA through agreement with NASA. The line-of-sight (LOS) is ~perpendicular to fault strike, so most of what you see is vertical motion at bends and steps of the fault.

A historical seismicity map shows several #earthquakes of similar size to today’s M7.7 in Myanmar occurred in the region in the early 20th century, but this section of the Sagaing fault probably hasn’t ruptured since 1839 🧪⚒️
