You all know how much I love maps of GPS tracked animals. This animation of bird migration patterns across Europe is extremely nice!

[Jascha Polet @CPPGeophysics]

I have not seen any seismic waveforms for this event, but I would assume there should be some?

Preliminary detailed displacement from image correlation for the main fault rupture (central part) of Mw 7.1 #RidgecrestEarthquake, using imagery from Google Earth. Much detail from 2m displacement field rasters. Junction w/July 4 NE-SW rupture at the southern end.

[Vincenzo De Novellis @VDN75]

A new possible scenario that involves more than 3 fault plane sources with @esa #sentine1 @unavco GPS @IRIS_EPO data.
Thanks @patton_cascadia for your report 2 and @SotisValkan for your S-2 maps!

High resolution displacement from image correlation using pre- and post- eq Google Earth images The July 4 #RidgecrestEarthquake Mw 6.4 rupture is visible in detail, up to the junction with the Mw7.1 NW-SE rupture. A lot of noise/errors but even w/ GE can identify fault features.

[Sotiris Valkaniotis @SotisValkan]

And the horizontal displacement results / image correlation (#MicMac) for #Ridgecrestearthquakes surface rupture, comparing pre- and post-eq high-res imagery. Profiles show coseismic offset (Not super-accurate - Imagery from GoogleEarth/DigitalGlobe@2019)

Complex and detailed pattern of co-seismic ruptures for the #RidgecrestEarthquake sequence. Red lines are primary & secondary surface ruptures, together with small triggered ruptures away from main faults. Previously mapped Quaternary Faults with yellow, for comparison.

[Sotiris Valkaniotis @SotisValkan]

Gradient render from unwrapped LOS displacement map (higher quality 20m from SNAP). Surface ruptures (major & minor) are easily visible as dark linear features (high displacement gradient). Processing in @esa_gep. Descending pair from #Sentinel1, #Ridgecrestearthquake

[Jose Manuel Delgado Blasco @DelgadoBlasco]

Very impressive what Nature does. Here the processed ifg @InSARinfo using @Sentinel1a data and @ESA_EO tools #SNAP. It contains the Earthquakes in South California occurred from 4th to 9th July. I counted 26 fringes. Coherence shows also some surface ruptures.

Descending interferogram #InSAR from #Sentinel1 data, #Ridgecrest #earthquake sequence. Rupture trace from previous InSAR & optical data. July 4 - July 16. Processed with DIAPASON at @esa_gep

[Xiaohua Xu @XiaohuaXu1]

More results using @ALOS2_JAXA data available on https://t.co/SSyQaHdJYh . What really needed is the other look direction. Waiting for 16th Sentinel-1. Also check out the north west corner. That's central valley going down.

[Xiaohua Xu @XiaohuaXu1]

A very preliminary fault slip model for #RidgecrestEarthquake, using data from GPS, @esa Sentinel-1, @ALOS2_JAXA, optical imagery from @planetlabs by @Geo_GIF. Model, surface displacement and Coulomb stress available at https://t.co/SSyQaHdJYh.

Found our BIGGEST offset yet for the fault that caused the M7.1 earthquake. This channel is offset about 13 feet! #ridgecrestearthquake #earthquake #ridgecrest
