Overview

• Scientists have identified seven distinct magma reservoirs beneath Yellowstone, with the northeastern region showing the highest activity and potential for future eruptions.
• The study used advanced magnetotelluric imaging to map magma distribution, revealing a complex system of interconnected reservoirs at depths of 4 to 47 kilometers.
• The northeastern reservoirs hold an estimated 388 to 489 cubic kilometers of rhyolitic magma, significantly more than other regions of the caldera.
• Researchers emphasize that while volcanic activity is shifting, the magma is not sufficiently connected to trigger an eruption in the foreseeable future.
• Yellowstone's last major eruption occurred 640,000 years ago, and experts suggest any future eruption is likely thousands of years away, based on current data.
