Our recent Nature Communications paper on off-fault damage has been highlighted by the KAUST Disvovery magazine, see here: https://t.co/opkfqWqd6m @Jihong_KAUST @KlingerYann

[Sigurjón (Sjonni) Jónsson @Sjonni_KAUST]

Great to see our Nature Comm. paper out on off-fault damage: It extends further than previously reported, correlates with fault geometrical complexities, and has implications for slip-rate estimates from geomorphology @KAUST_PSE @Jihong_KAUST @KlingerYann https://t.co/9iIZpDe0gb

📣📣Our new paper is now published in ⁦⁦⁦@NatureComms⁩!

We explore interseismic strain variability along the 1600-km Altyn Tagh Fault in the Northern Tibetan Plateau.

**New Paper Alert**
"Mitigating Atmospheric Delays in InSAR Time Series: The DetrendInSAR Method and Its Validation" (https://t.co/HD2MnGkCsS). The proposed DetrendInSAR method simultaneously models both the spatially smooth (Trend) and DEM-correlated components.

[Jihong Liu @Jihong_KAUST]

The key point is to model different components in InSAR time series based on their spatiotemporal characteristics. You can access the code and demo cases at https://t.co/IdMd4mLtUe.

Active fault trip to Greece by @IPGP_officiel tectonics group is on the road again. This year some students from @Sjonni_KAUST and @Prof_QuakeMod from KAUST, Saudi Arabia, are part of the legends

Great, thanks @ALOS2_JAXA

[Ziyadin Çakır @ziyadin]

Good news! Here is the link for ALOS-2 SAR data set for the Kahramanmaras earthquakes. Huge thanks to JAXA. @ALOS2_JAXA @JAXA_en @AktifTektonik #TurkeyAndSyriaEarthquake #earthquake https://t.co/AlQAfT87Qc

Our current version of the fault-slip model of the 6 Feb. 2023 Kahramanmaras earthquakes, estimated by @XingLisom based on data processed by @Jihong_KAUST, as part of the CDI and @CES_KAUST group efforts. @KAUST_PSE 1/5

[Jihong Liu @Jihong_KAUST]

@EricFielding @timwright_leeds @Sjonni_KAUST @EO_OPEN_SCIENCE Thanks Professor Eric Fielding, I checked asf, the SLC is also not available.

[Jihong Liu @Jihong_KAUST]

The raw data is there, but the slc not

[Jihong Liu @Jihong_KAUST]

Can anyone get the ascending #Sentinel1 frame along track 116 that covers the #TurkiyeEarthquake on 16th Feb.? Other frames along this track are almost available, but only the frame covering this earthquake. It's really strange. @Sjonni_KAUST

[Jihong Liu @Jihong_KAUST]

@timwright_leeds @Sjonni_KAUST @EO_OPEN_SCIENCE Thanks Tim, it's right that the raw data is available but SLC is not.

[Jihong Liu @Jihong_KAUST]

@simon_sat @Sjonni_KAUST @niklas_jordan Really? I still can't see that frame

[Jihong Liu @Jihong_KAUST]

@mahiraksin @Sjonni_KAUST The marked zone is the coverage of satellite data, no relationship with the possible earthquakes.

#TurkeyEarthquake Displacement from Burst Overlap Interferometry on Sentinel-1 images!
We can resolve clear displacements from double-differencing dense #InSAR fringes.
It is a preliminary BOI result, which still needs phase unwrapping.

[Sigurjón (Sjonni) Jónsson @Sjonni_KAUST]

Coseismic displacements near the two faults are asymmetric, in part due to opposing motion between the two faults. This prelim. result is from Sentinel-1&2 offsets by @JinhongLiu4 here at #KAUST as a part of the CDI and @CES_KAUST group efforts. @KAUST_PSE @ESA_EO 1/5
