Turkey-Syria Earthquake displacement from pixel tracking with Sentinel-2 imagery. Data at: tinyurl.com/4cbs8kuw

InSAR image of the ongoing strong earthquake sequence near Reykjavík. Looks like ~30 km of the ENE-trending plate boundary moved left-laterally at depth with several coseismic N-S right-lateral strike-slip surface ruptures on top, including the one of the magnitude 5.7 earthquake

WOW....! Just now! #earthquake swarm on Reykjanes Peninsula #Iceland - very strongly felt in Reykjavík. My home office was shacking! Felt 2 large ones and many small ones. Reykjavík is in 30-40km distance from the epicenters Check @Vedurstofan for real time earthquake locations

For clarity: here is a before (6th Feb) and after (7th Feb) render of @planetlabs imagery showing the glaciated slope that failed #ChamoliDisaster #Uttarakhand

Care home deaths are going up again Spent a bit of time today with the manager of the very first home I went to in the crisis, in Hove on the south coast, back at the very start of April The picture she and her colleagues paint isn't a good one.

🔥🔥HOT OFF THE PRESS🔥🔥 Our new paper uses cosmogenic exposure data from two faults in the Italian Apennines to resolve detailed millennial earthquake slip histories. Exciting work from Huw Goodall's PhD (supervised by @theearthquakes) agupubs.onlinelibrary.wiley.com/doi/abs/10.102…

There is more red tape. The fishermen are worse off. There is no frictionless trade. There is a border in the Irish Sea. America is not coming to the rescue. And the Vote Leave government is now delivering the worst Covid death rate & one of the deepest recessions in the world.

🚨🇬🇧🇪🇺🚛🍤🐟🥬📦✈️🇬🇧🇪🇺🚨 So here it is. After the euphoria, the @FinancialTimes @FTMag long read of how @BorisJohnson did his Trade deal with the EU. Tl:dr...not so much “build back better”, more “build back the borders” - stay with me/1. on.ft.com/3c0vhPX

PAPER ALERT!!📢 "Nationwide urban ground deformation monitoring in Japan using Sentinel-1 LiCSAR products and LiCSBAS" by Y. Morishita doi.org/10.1186/s40645… The results can be viewed on a web map: yumorishita.github.io/gsimaps_S1_Jap… #LiCSBAS #InSAR

LONG THREAD: Digging into UK Covid numbers & what they mean & what's in store... TLDR: everything is bad and getting worse. Except vaccines. They are a shining light - we just need to give a LOT more of them. Read on (25 tweets!)...

Gov website has been updated with: “Higher Education provision will remain online until mid February for all except future critical worker courses.” gov.uk/guidance/natio… #university #Lockdown3

Key questions -When will it end? No real sense of that, v striking no time limit was offered. -PM put a lot of emphasis on the new variant, saying the old measures would have worked with the old strain. Not all public health experts agree...

1/ We are incredibly proud to officially be the highest resolution commercial #SAR provider in the world! Today we are revealing our “Spot” imagery at 50cm x 50cm. 👉 bit.ly/3r3zAz1

Chris Rollins will be giving a talk at #AGU20 this afternoon titled 'Tectonic strain rates across the central Alpine-Himalayan Belt from Sentinel-1 InSAR and GNSS observations, and implications for seismic hazard' @NERC_COMET @SEELeeds G018-06 15:20 - 15:24 UTC #AGU20

Talk featuring work by @iris_van_zelst on 'Modelling splay fault rupture and tsunamis with self-consistent initial conditions from a geodynamic seismic cycle model of subduction' @NERC_COMET @SEELeeds DI009-04 18:42 - 18:46 UTC #AGU20

Looking forward to my talk on Friday (4 pm UTC) @RoyalAstroSoc Ordinary Meeting! I'm boldly going...to chat about: "Seismic reflection data and space exploration" Based on work with @seis_matters @ThePlanetaryGuy @planetarydrone Sign-up here: ras.ac.uk/events-and-mee…

SAR coherence can be used to detect landslides after an earthquake, but which method works best? Check out our new paper “A systematic exploration of satellite radar coherence methods for rapid landslide detection” to find out! @_IHRR @DurUniEarthSci nhess.copernicus.org/articles/20/31…

Due to a time gap between spectral bands, a Sentinel-2 scene can represent ~2 seconds of activity on the Earth's surface. Useful for many things (eg. vehicle detection), I've made a #GEE app to easily explore this feature (and enjoy gifs of avalanches!) spiruel.users.earthengine.app/view/sentinel-…

I hope you are all ready for me to advertise #vEGU21 over the next 7 weeks! I'm convening "TS2.1: Deformation mechanisms and microstructures", so if you work with microstructures from the field, experiments and models, this is the session for you! meetingorganizer.copernicus.org/EGU21/session/…
