Yellowstone Eruption Update | October 2025 Scientists reanalyzed seismic records and found 86,000 micro-earthquakes beneath Yellowstone that earlier methods missed. Microquakes help map where fluids and hot rock move and why the caldera remains active. Ground motion and swarms can shift over time, which is why monitoring combines seismic data, GPS uplift, gas, and temperature. This does not mean an eruption is imminent, but it is a reminder that Yellowstone is alive and under constant watch. In

🚨 YELLOWSTONE IS MOVING AGAIN A new update from the Yellowstone Volcano Observatory confirms that the caldera has resumed subsidence – in simple words, the ground in parts of Yellowstone is slowly dropping. This sinking restarted in mid-October after the usual summer pause, and it sits on top of a long trend of subsidence that has been going on since about 2015. We also now know, from new studies, that Yellowstone has huge, complex magma storage zones, not one simple chamber. Only a fraction of

When Yellowstone’s supervolcano erupted 2.1 million years ago, it made a hole the size of Rhode Island. Makes you wonder what will happen the next time it erupts. | National Geographic TV
