Yellowstone Alert: 200 Earthquakes In 10 Days As Ring Of Fire Awakens
According to a group of seismologists who are monitoring the potentially catastrophic supervolcano, Yellowstone is “under strain.” This new report has reignited fears that the caldera could erupt at any moment.
Experts were alerted to the volcano’s strain after noticing deformation. This process, where subsurface rocks subtly change shapes, is occurring beneath the surface of Yellowstone right now. Researchers state deformation occurs when there is a change in the amount of pressure in the magma chamber and experts are keeping an eye on the development.
Seismologists from UNAVCO, a non-profit university-governed consortium, are using “Global Positioning System (GPS), borehole tiltmeters, and borehole strainmeters” to measure minute changes in deformation at Yellowstone. In an article for the Billings Gazette, David Mencin and Glen Mattioli, geodesists with UNAVCO, say “the strain signal is larger than would be expected if the crust under Yellowstone were completely solid.”
