Megathrust earthquakes are among Earth’s most destructive hazards. Oryan et al. developed the Coupling Cloud, which unifies and standardizes megathrust coupling models into one community-driven platform for easy visualization, comparison, and access.

#InSAR analysis for M8.8-2025 #Kamchatka Peninsula, Russia Earthquake

We retrieved the coseismic deformation from the 2025 M8.8 event using #Sentinel1 InSAR, revealing a maximum ~1 m line-of-sight displacement in the southern part of the Kamchatka Peninsula.

The June 2025 update for the reconstruction in La Palma for @GeoTenerife's #VolcanoStories project is up and available to read here: https://t.co/mWlPZTpQpl 🌋🇮🇨

Here's a quick update of the main stories from this month

Earth's surface is always moving – and NISAR will soon track even the tiniest shifts.

Set to launch soon, the satellite will use advanced radar tech to track changes in Earth’s surface, helping us better understand everything from ice loss to natural hazards. Learn more ⬇️

[GeoGeorgeShadrach @GeoGeorgeology]

Holy shit! This is incredible footage of surface rupture forming on the Sagaing Fault during the #MyanmarEarthquake in Thazi. It's the first time such a phenomenon has been captured!

[ESA Earth Observation @ESA_EO]

The first images from the @CopernicusEU #Sentinel1 C satellite are here!

📸 Svalbard
📸 Amsterdam and the region of Flevoland
�� Brussels

Fun fact: Brussels was the subject of the first radar image captured by Sentinel-1A in April 2014.

Are you interested in studying volcanoes, earthquakes and/or tectonics at doctoral level? Funded opportunities with @NERCscience @UKRI_News you might even get to work with @esa 🙌🌎 #PhD #volcano #earthquakes #Students #university #EarthSurface #satellites

[Zhang Yunjun @yunjun_z]

Excited to see our work on the 2024 Noto EQ led by @liuwei_xu, Ji Chen, and @LingsenMeng featured on the cover of @ScienceMagazine! Combining seismic & geodetic data, we found complex ruptures in the initial stage of this New Year's EQ that led to violent shaking

[Seismica @WeAreSeismica]

Is there any evidence of Slow Slip Events in the southern Peru-northern Chile subduction zone?

Yes, (@cokejaragomez)Jara et al. find tiny events hidden in the geodetic noise. Read more to see how they detected and characterized them:

Almost ready! A new trench on the San Ramón thrust fault… #PATAChile2024 website launch in the upcoming days! ⁦@UChile_Geologia⁩ ⁦@paleoseismicity⁩ ⁦@terpro_inqua⁩ ⁦⁦@Josgonal⁩

[Dr. Judith Hubbard @JudithGeology]

A M7.0 earthquake struck the China-Kyrgyzstan border just after midnight, in bitter cold. With severe shaking, this event is likely serious.

The quake likely occurred on the South Tien Shan fault, which in the past has produced M8+ events.

PAPER ALERT!!!

I am happy to share the publication of my PhD work. @NatureGeosci

With @DocTerremoto and @AndresTassara, using numerical simulations of earthquake cycle, we investigate the feasibility and behaviour of Velocity Weakening barriers.

[@MAST_ERC @mast_erc]

Last week it was MAST’s first annual meeting! 🌋🛰️

We welcomed researchers from @UoBEarthScience, @bristolcs, as well as Catherine Annen from @CzechAcademy and Sylvain Barbot from @USC, to discuss science, collaborations and progress!

Map of M7.4 Alaska shallow thrust earthquake today (approximate location with green star) in tectonic context using a figure from the 2021 Chignik earthquake paper from Ye et al. (2022). Today’s event appears to be located in Shumagin gap area.

[@MAST_ERC @mast_erc]

MAST takes #Comet23 @NERC_COMET! Lots of talks and posters from the group this conference, look out for our logo on our talks and posters, and come chat to us! 🛰️🌋

@UoBEarthScience @UoBristolVolc

[Ben Ireland (@benirevolc.bsky.social) @BensVolcanology]

Back from fieldwork and now at @BritGeoSurvey where #COMET23 @NERC_COMET has begun!

Looking forward to a fun few days of earth observation and modelling conversations! 🌋🛰️

Lots of @mast_erc and @UoBEarthScience representation, with a great early talk by @EdnaDualeh
