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

Ooooh! Pretty great job with this article highlighting some of the major players in California. I find very little fault with it! www.sfchronicle.com/projects/202...

Map: 10 California faults that could produce major earthquakes

See where the San Andreas, Hayward, Cascadia and other major California earthquake faults run — and what risks they pose.

The Papatea Fault, a previously unmapped oblique active fault that ruptured violently during the magnitude 7.8 Kaikōura earthquake in New Zealand on. It produced a vertical surface displacement of up to 9.5 meters #activefaults

Forces of nature. The thread and the needle: The structure symbolizes the act of “sewing together” the crack in the ground created by the paleo-earthquakes exactly above an active fault scarp. Symbol of the people efforts to tame nature and protect themselves from natural events. #wellingtonfault

Vertical surface motions in Europe. I love the Copernicus EGMS! Scandinavia goes up due to postglacial rebound. Po Plain sinks because of sediment input, compaction, and flexure caused by Apennines and Alps. egms.land.copernicus.eu

A map of Europe, colour coded by uplift vs. subsidence. Scandinavia goes up, most of Europe is stable, Po Plain and Netherlands go down

Here I wrote about the PATA Days meeting on active tectonics, and about the field trips I led in Guatemala.

Impressive normal fault in western Guatemala! #patadays post-congress field trip

The pre-meeting field trip of the 2026 PATA Days starts from Antigua Guatemala with 40+ people from 15 countries. Three days of paleoseismology, archaeoseismology, and active faults ahead of us.

#patadays Day 3. Another spectacular evidence of Motagua fault, in a complex structural bending at La Laguna. Trastensive cinematic, well expressed in a paleoseismological trench.

#patadays Day 2. The rupture of 1976 eq. on the Motagua fault, and his offset along a canal

#patadays in Guatemala. Day 1 of the pre-congress field trip. Paleoseismological trench of 1976 left lateral strike slip of Motagua fault.

If you were far away from the Earth, on a line that intersects the centers of the Sun and the Earth, here's the sunlit half of the Earth you would be seeing during the June and December solstices. Two very different views of Earth! 🧪 denis-gilbert.ca/en/2025/04/2... #solstice #astronomy #animation

Huge active fault plane at Genoa ridge, perfectly E-dipping! #normalfaults #sierranevada
