How IGN maps take into account the changes affecting high-altitude mountain areas in the latest editions? 🗺️ 🔥 Examples: - Change for ‘Former glacier of...’ (in black font) - Depiction of morphogenic changes following recent extreme events (e.g. La Bérarde) 1/

It appears that JMA early warning system issued a false alert for a magnitude 9.9 😱 #earthquake. They cancelled it 8 minutes later. It's now under investigation and still unclear why this false alert. ⚒️ www.japantimes.co.jp/news/2026/10...

NISAR satellite passed over 9 October 2026 magnitude 7.7 earthquake in Azuero Peninsula of Panama about 6 hours after. Maps below are from slant-range and along-track offsets in Urgent Response geocoded offset (GOFF). Fault ruptured to surface, and surface displacements were measured well by GOFF.

Another flow disaster in Nepal, just one catchment to the west of the Trishuli. This one is also caused by a landslide, but with a different mechanism - the landslide dammed the river and an outburst flood followed. Landslide was at 4:22 local time, and the largest flood pulse started around 6 am.

My latest @newscientist.com cartoon

The magnitude 7.7 #earthquake in #Panama has a shallow depth hypocenter (12-14km) and a strike-slip / normal mechanism 👇. It seems to be a crustal event within the Panama #tectonic microplate. The epicenter is near the Sona-Azuero fault, which traverses the Azuero peninsula. ⚒️

None of this year's science Nobel Prizes have gone to women. The number of these prizes to go to women remains at 27 out of more than 600. See how many you can name in our quiz: www.nature.com/immersive/d4...

www.theguardian.com/commentisfre... After huge demonstrations yesterday: "As the social contract in France comes under increasing strain, the voice of its protesting students needs to be heard."

It’s a quintessential French experience when your institution is blockaded by protesting students. This is precisely what American students should have done when their institutions began capitulating to the Trump regime.

Une alerte météorologique "extrême", pour reprendre le terme du message FR-Alert reçu sur les téléphones pour toute la population, est en cours dans le Gard et l'Hérault. Les dernières prévisions sont terrifiantes entre 300 et 400mm de pluie en villes. La population est invitée à se confiner.

In case any one doubts that geomorphology and paleoseismology are unrelated. Trenching the Fuyun fault now.

Hundreds of scientists around the globe have been working tirelessly to piece together the sequence of events that led to the devastating flood in Tibet and Nepal, which has killed nearly 600 people, left nearly 2000 missing, and destroyed many towns and hydropower plants. https://scim.ag/3SErvn3

La catastrophe au Népal a été induite par un effondrement de glacier du Langtang Lirung, à une altitude d'environ 5200 mètres. Que sait-on du lien avec le réchauffement climatique dû aux activités humaines pour les glaciers de ce secteur ? 1/...

Excellent article in @theguardian.com about the catastrophic glacial collapse and flash flood in Tibet and Nepal. www.theguardian.com/world/2026/a...

Dreadful scenes from the devastating Rasuwa flood in Nepal/Tibet. My heart goes out to everyone affected. It likely began with a glacier collapse / rock–ice avalanche recorded by seismometers worldwide. I hope real-time seismic monitoring can support early warning for communities downstream.

Some early reports said that the horrifying flooding in Nepal was the result of an earthquake. However, the signal was actually the recording of the landslide. TL:DR - there was no earthquake, it was a landslide. earthquake.usgs.gov/earthquakes/...

A new video emerged which seems to show a surface rupture in Yatsushiro, Japan following the M6.8 earthquake in July! Exact location of the video would be 32°30'04.0"N 130°38'29.9"E. Absolutely wild. Only the second ever video of a surface rupture forming after the 2025 Myanmar video! ⚒️🧪 #geology

An #earthquake of magnitude 6.8 happened close to Kumamoto in the island of Kyushu (SW Japan). Japan is prone to frequent subduction earthquakes, but in this case, the shallow hypocenter depth and strike-slip mechanism imply a rupture in the upper plate. ⚒️ 🧪

Yesterday afternoon 14:09 in Lacanau Océan in France. A pale red sun through the smoke tinged everything in Mars style orange. Welcome in the climate emergency! Despite all denial of the fossil fuel lobby, it’s scientific fact: CO2 emissions heat up Earth & make fires worse. 🔥🔥🔥

Lacanau Océan 24 juillet 2026.🔥🆘 L’augmentation des températures globales due à la combustion d'énergies fossiles rend plus intense/probable l'asséchement de la végétation (y compris à pluviométrie annuelle constante), nourrissant ensuite des incendies XXL.

What have we learned about the deadly Venezuela earthquake in the last day and a half? A lot, actually. earthquakeinsights.substack.com/p/early-scie...

Composite plot of the two coseismic interferograms (Sentinel-1, from Copernicus) with the USGS epicenters of the two earthquakes and faults from GEM. The shoreline San Sebastián fault lines up with the fringes in the west and is probably the fault responsible.

⚒️ 🧪 A catastrophic earthquake just struck northern Venezuela. Large buildings have collapsed, and the USGS PAGER is forecasting thousands of fatalities. Our colleague in Caracas, Dr. Frank Audemard, has shared with us what the earthquake felt like and footage from the region. Here’s what we know.
