Newly available high-resolution satellite imagery collected by Maxar reveals sections of the surface rupture near the zone of maximum surface displacement of last week’s Mw 7.7 earthquake in Myanmar. Rupture is ~500 km long, with up to 5 meters of fault slip.

Sentinel-2 optical imagery pixel offset results (Cosi-Corr, 20250320-20250330) reveal a fault trace highly consistent with the Sagaing Fault in the GEM.

The #MyanmarEarthquake broke a seismic gap identified by Hurukawa and Maung (2011), called the Meiktila Gap. They prev. estimated a M7.9 earthquake here.
Possibly, the last EQ on the gap was in 1839, Mw7.9–8.3.

After the March 28 Mandalay Earthquake, around 100-ft-deep sinkhole has formed west of Demoso, Karenni State. Locals report it’s still expanding. Nearby, Namsanphu river level dropped 3 ft, with discolored water.

A user from Myanmar filmed what appears to be offset in a water channel caused by the earthquake. Looks like the fault surface was also exposed

Massive destruction reported from the Sagaing earthquake (7.7M) at 12:40 PM, March 28, 2025. Widespread building collapses, severe damages, and communication disruptions in Sagaing Township which is just 3 miles away from epicenter. #MyanmarEarthquake #Sagaing

Preliminary coseismic displacements and fault offset of 2025 Myanmar earthquake from @CopernicusEU @ESA #Sentinel2 images, processed by @NTU_TW GEOG
#Copernicus
1. Rupture propagated from N to S
2. Maximum offset >4m
3. Two peaks of fault offset
4. Rupture length >300km

Un altro incredibile video della liquefazione del suolo innescata dal #terremoto in #Myanmar: l'acqua cerca la via più rapida per raggiungere la superficie e lo fa sia attraverso i pozzi già esistenti che creando nuove fratture nel terreno, anche coi famosi vulcanetti di fango.

Surface ruptures were already identified from the Mw 7.1 Xizang Southern Tibetan earthquake. Scarps up to 3 m. See link in Chinese but with photos mp.weixin.qq.com/s/qtB9yU9E6…

Good morning, here's an offset moraine for you. It's near Cusco, Perú: maps.app.goo.gl/obDVhAGXupdz… on the Pachatusan Fault. If the moraines are LGM (∼10–45 ka), the offset implies a slip rate of 0.4–2.0 mm/yr.

ALT View towards a mountain. A small u-shaped valley is bordered by two ridges, which are lateral moraines. These moraines have two steps, caused by normal faults.

Ohhh, today's GoogleScholar alert had so many interesting papers I'd like to read immediately.
One is Gautier et al. on the HFT in Bhutan
(nature.com/articles/s43247-0…), another one is Barth et al. on curved slickensides on the Alpine Fault pubs.geoscienceworld.org/gsa…

#fridayfault is of course a reminiscence of a recent visit in Chile. Mesozoic volcanic rocks overthrust on the Plio-Pleistocene beach facies

This pretty cool “geoslicer” was home-made by local engineer Lesli in Chile per Marco Cisternas request . Only at Chile #PataDays2024 🥰🌊 check my Lidar 3D of the 🌊trench m.3dscannerapp.com/m?id=cXiy…
We conclude this PATA Days 2024 with a fantastic field trip to explore tsunami deposits. Many thanks to Marcos Cisternas and his team. Tomorrow, the Post-Meeting Field Trip to Argentina begins. Thanks to everyone who participated during this week! ❤️
