NEW ANIMATION! Volcanic evolution of the Pacific Northwest: A 55 million year history

This animation integrates the unique and rich eruptive volcanic history of the Pacific Northwest in relation to the complicated tectonic regime revealed by seismology and geodetics in recent decades. We weave together geologic maps, time scales, and cross sections to help simplify and clarify elusive hidden structures and processes below Earth’s surface.
