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.


Intensidad de Terremoto: ¿Que controla la sacudida que sientes?

La intensidad sísmica, que es el temblor que experimentas, puede ser leve o severo, corto o largo, brusco o de bandeo. A diferencia de la magnitud de un terremoto, que es una medida de la energía liberada y es la misma para todos los lugares, la intensidad sísmica que percibes depende de dónde te encuentras.
