20 hours ago · JACKSON, Wyo. — Last month, the Yellowstone Volcano Observatory (YVO) published its 2023 Annual Report with new insights into lava flow eruptions within the Yellowstone Caldera. Results from dating lava flow eruptions between 160,000 and 70,000 years ago suggest the possibility of multiple lava flows happening at the same time, challenging the previously held belief […]
