Which city has the coolest exposed geology coexisting with urban structures?
My fav: the massive dikes visible on a walk in downtown Nuuk, Greenland. Bonus pic from the hills on the outskirts of town
Fault activity during earthquake caught on video for a second time
Fault movement has been caught on video surveillance in the July 2026 "Kumamoto" earthquake in Yatsushiro City, Japan. Geologists led by Professor Chiba of Kunamoto University harvested rice by hand in order to avoid damaging the fault terrain and study the fault.
Once the land was cleared, Professor Chiba commented that the terrain was well-preserved and surprisingly easy to understand. While the video appears to depict the rice field rising up, the section with the camera actually subsided (dropped) by 80 cm and moved laterally by 1 meter.
As this is only the second instance ever of earthquake fault activity being caught on video, Professor Chiba hopes to preserve the area for research and disaster education, including the buildings which sustained damage in the earthquake.

I’m building Metallo, a map for exploring mineral resources and the geology behind them
Hi everyone,
I’m building Metallo, an app for exploring where mineral commodities are found and the geological and tectonic context around them.
I’m also making Metallo Labs: interactive explainers about the minerals in everyday technology, like phones and GPUs, and how a mine goes from exploration through restoration.
It’s an ongoing project. Take a look and let me know what you think!
