What if tectonic plates aren’t as solid as we thought?

Thanks to satellite data from @CopernicusEU Sentinel-1 and other data sources, scientists have mapped how the Tibetan Plateau stretches and shifts, showing that Earth’s crust and upper mantle behave more like flowing material.

It is a team work! We mapped stress shifts in 2025 Dingri Earthquake from earthquake cycle observations.

New paper alert. Volcanic crisis reveals coupled magma system at Santorini and Kolumbo. Great work led by Marius and Jens, thanks all for working on that together! It can be found in today’s issue of Nature.

Temblor's analysis of the July 2025 magnitude 8.8 Kamchatka quake explores some mysteries, and finds that the 10-day foreshock was exceptionally productive. Find out more in our latest, led by CEO @rstein357

Odd rupture process of 2025 Myanmar earthquake revealed by tele-P waves: not only supershear rupture but also a Boomerang-like backrupture. Three segments were ruptured. (Inoue et al.) https://t.co/YIE674x9sL

[Hirano, S. @Bimaterial]

I analyzed the distance between two edges in the video during surface rupture due to the M7.7 Myanmar earthquake.

🚨 With Sentinel-1A & 1C in action, the 6-day ifg is back! 🌍📡
Our quick InSAR results capture ground displacement with horrible fringes.
Meanwhile, our thoughts are with those affected by the recent earthquake in #Myanmar. Stay strong. 🙏

[ZhangFeng Ma @MarsZeff]

@JudithGeology @zhenjiangliu4 Zhenjiang might wrongly label "1 pixel" as "1 m". For Sentinel-2, the resolution is ~10 m.

Preliminary coseismic displacements and fault offset of 2025 Myanmar earthquake from @CopernicusEU @ESA #Sentinel2 images, processed by @NTU_TW GEOG
#Copernicus

1. Rupture propagated from N to S
2. Maximum offset >4m
3. Two peaks of fault offset
4. Rupture length >300km

[Zhe Jia @jiazhe868]

#MyanmarEarthquake may be a long supershear event (~5 km/s, ~350 km rupture), evidenced by S wave arrivals on the strong motion data, which explains strong shaking felt far away. Supershear amplifies damage, calls for urgent rescue needs & infrastructure strengthening.
