Yellowstone's Dormant Volcano: Scientists Assess Preparedness for Potential Eruption

Scientists studying the Yellowstone Volcano have deployed 650 temporary seismometers to measure seismic wave speeds in the magma chamber, resulting in the best image of the chamber ever seen. The research has revealed that the magma chamber is stratified, with partially molten sills towards the top. The study also suggests that the percentage of semi-liquid or melt material in the chamber may be higher than previously thought, possibly as high as 28%. However, experts emphasize that this does not mean an eruption is imminent, as a melt percentage of 50% is needed for the magma to become mobile. The research provides valuable insights into understanding volcanic systems and improving eruption forecasts. Scientists urge the public to rely on information from experts and not be swayed by sensationalized headlines and misinformation.

Multiple Explosive Events Observed in Yellowstone Volcano Super-Eruptions

New geological evidence suggests that the last super-eruption at Yellowstone volcano, which occurred 631,000 years ago, was not one huge explosion but a series of eruptions or multiple vents spewing volcanic material in rapid succession. Scientists have found four previously unrecognized ignimbrite units at Sour Creek, suggesting at least four eruptive pulses. They also found two structures that appear to be eruptive vents, which may have been the sources of these rocks. Researchers at the volcano now plan to carry out detailed examinations of the newly discovered units and the boundaries between them.
