HOT UPDATE : ISRO released almost all it's datasets for FREE - for everyone. INDIA now has one of the most progressive & high resolution datasets available for free for it's users.

I just downloaded a dataset from 1990 - 5 YEARS before I was born. What all is free now? 🧵(1/n)

The Geotechnical and Geological hazard team responded immediately to a major landslide that occurred in the mountainous region of Xanthi. Site investigation works included a survey through the use of UAS and the development of a 3D model.

Pre-print alert! 👋Introducing a probabilistic displacement hazard assessment framework for distributed ruptures from strike-slip earthquakes on immature faults. We are VERY interested in community feedback, Mike Oskin and I are pretty new to PFDHA! eartharxiv.org/repository/vie…

Melgar et al. used HR-GNSS and strong motion data to create kinematic rupture models for the Türkiye earthquake doublet. Their results reveal both sub- and super-shear rupture behavior of these events.

Check out doi.org/10.26443/seism… for more details.

Μέσα στον πόνο μας που χάσαμε το Βαγιακο μας, βλέπω τι λέτε τώρα πολλοί και πολλές από εσάς στα κανάλια που με φιλοξενήσατε και με βοηθήσατε όσο τον ψάχναμε.

Και ένα έχω να σας πω:

A preliminary report of liquefaction phenomena triggered by the Feb 6 2023 earthquake in Turkey/Syria can be downloaded via the following link. We mapped 750 sites with liquefaction and lateral spreading using EO zenodo.org/record/7668401 GeorgePapathanassiou

Here's our kinematic model for the Türkiye doublet on a 3D geometry from HR-GNSS and strong motion. Penomenal effort by Prof.Dr. Tuncay Taymaz , Athanassios Ganas, Brendan Crowell and many others. This was a fast and furious multinational work with folks in Türkiye, Greece, and the US (1/n)

First results of 3D surface displacement derivation for the Turkey earthquake (from Sentinel-1 pixel offsets) showing ~8 m fault offset on the 2nd fault, but limited vertical motions. Processed by @JihongLiu4 at , as part of the CDI and CES_KAUST group efforts

An interesting observation from optical displacement; significant displacement along the NNE-SSW Narli fault, close to the M7.7 epicenter. Displacement mapping shows a previously unmapped ~5km section to the north of Narli F. 🧐twitter.com/SotisValkan/st…

An updated version of fault offset along a ~13km splay section of EAFZ from the Feb 6 M7.7 . Data not clean or accurate but offset follows mapped fault trace. Waiting for raw & new satellite images. post-eq imagery from Maxar Technologies

A very crude first look of surface fault offset along the East Anatolian Fault trace from the Feb 6 M7.7 . ~3m of North-South displacement & ~1m of East-West displ. Fast run with post-eq imagery from Maxar Technologies satellite imagery
