This matches very well with traces of the surface rupture visible a few km to the north on the high resolution Planet SkySat images (thank you Planet!). The offset road is the northernmost point on the overview, and I measured about 4.5 m of offset there.
Satellite image of part of the area affected by the Myanmar earthquake. The lower left of the image has large and small buildings. The lower right corner shows a river. A linear ridge goes up the middle. To the left of the ridge are a series of blue dots more or less n a line. Closeup of satellite image. A white road goes across the middle, with trees below and a field above. The road is cut and offset by about the road width.

Update: Preliminary coseismic displacements of 2025 Myanmar earthquake from @CopernicusEU @ESA #Sentinel2 images by using #CosiCorr, processed by @NTU_TW GEOG
#Copernicus

1. Rupture propagated from N to S
2. Max. offset >4m
3. Rupture length ~500km

Felipe Vera of @gfz.bsky.social shows an initial bilateral subshear rupture, yet the southward portion propagated much more at supershear velocities, cumulating to a "well over 400 km" long rupture!

The @ipgp.bsky.social #Geoscope solution 👇 shows mechanism of #Myanmar #earthquake (strike-slip, likely dextral rupture on #Sagaing fault) and the source time function with a rupture duration of 2 minutes. Magnitude is determined to be Mw7.9 with this solution.

Map showing the location of the earthquake on the sagaing fault. The fault is shown by a blue line. The mechanism of the earthquake is also shown as well as the source time function.

@alomaxnet.bsky.social (Lomax) uses aftershocks as virtual observations at the depth of rock deformation surrounding an earthquake rupture to image in 3D the fault slip during the earthquake.

Distributed Acoustic Sensing (DAS) has great potential for rapid response seismic deployments, but can it replace existing seismometer deployments? Van den Ende et al. put this idea to the test.
