Axial Seamount: Oregon’s Underwater Volcano Hits 90% Pre-Eruption Level with 1,000+ Daily Quakes

Three hundred miles off Oregon’s coast, a submarine volcano is swelling with magma. Scientists monitoring Axial Seamount have recorded more than 1,000 earthquakes per day during late March and early April 2025, signaling that this underwater giant is preparing to erupt for the first time since 2015. “It’s at or almost at that inflation threshold where it erupted last time. So we think it’s ready to erupt,” explains Bill Chadwick, a volcanologist and research professor at Oregon State University who’s been studying the volcano for 30 years. Nature’s Underwater Laboratory Sitting nearly a mile deep in the Pacific Ocean, Axial … Continue reading Axial Seamount: Oregon’s Underwater Volcano Hits 90% Pre-Eruption Level with 1,000+ Daily Quakes
