Permanent deformation of the Earth and its surface happens after *every* earthquake, no matter it's depth or distance.
This has been known to seismologists for decades, because we can see the permanent offset in our seismograms. With large earthquakes, even 100s of km will still cause mm of offset.

Recovering permanent displacements from seismic records of the June 9, 1994 Bolivia deep earthquake
Ground displacements of the 1994 deep Bolivia earthquake are recovered from six on-scale velocity records of a temporary array located ∼600 km south of the epicenter. I first removed the instrument (...

Went out downtown tonight and got leathered with my friend Gordon. (No reason, except Friday.) On the way home, my Uber driver asked me lots of fun questions about earthquakes. And now I'm home and learning that NISAR successfully deployed its reflector?! What a great evening!
Final deployment of the NASA-ISRO SAR (NISAR) satellite, the 12-meter radar antenna reflector was successfully completed August 15. Congratulations to all people involved in this important milestone of the mission, in USA and India. #NASA #ISRO #SAR #satellite #NISAR www.jpl.nasa.gov/news/giant-r...

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!

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) ⚒️ 🧪
