Sentinel-1C(!) acquired new SAR data over Myanmar yesterday. Here are the azimuth and range offsets. Not particularly unexpected (right-lateral slip, 400 km+ long rupture), given earlier InSAR/image offset results, but surprisingly clean, given S1C is not out of its commissioning phase.

Today's #earthquake near Mandalay, Myanmar, had magnitude Mw 7.7 to 7.9. Prelim. source models point to rupture duration & length of ~120s and at least 200km. It likely filled large part of seismic gap S of Sagaing (previous rupture in 1839) ⚒️ 🧪 Map from doi.org/10.1002/2013... (Wang et al.) 1/n

Looking at Sentinel-1 data availability over the Sagaing fault, and it is going to be several days (April 3rd) before Sentinel-1A flies over the likely rupture zone again. Can anyone at @esaearth.esa.int advise on the possibility of Sentinel-1C acquisitions over the area? #MyanmarEarthquake

Did you know that your 20 Mpx camera is actually a 5 Mpx camera for red and blue, and a 10 Mpx camera for green, thanks to the Bayer RGGB mosaic of your single chip camera? You can read the BaRAW files into #MATLAB with RAWREAD without interpolating them to RGB, use IMSHOW – and see the mosaic!

⚒️ If you are puzzled by shallow slip deficit during strike-slip earthquakes, maybe diffuse deformation is part of the answer. S. Antoine et al. revisited the Ridgecrest earthquake and got ride of almost all of the SSD by better accounting for off fault deformation. dx.doi.org/10.1029/2024...

A few higher level observations and speculations (mostly of interest to other seismologists probably): all aftershocks are located to the east of the M7.0 earthquake: eastwards rupture? And the source time function shows two pulses, maybe a subevent closer to the coastline (stronger shaking)? 🧪⚒️

Today's M7.0 earthquake off northern California was not a subduction earthquake, but is an important reminder for us in Cascadia (northern CA to northern Vancouver Island) that different types of large earthquakes occur here.
