The modern Seattle fault zone cuts directly through the densely populated Puget lowlands, including Seattle and its metro area. Fifty million years ago, the continent tore in two here, setting the geologic stage for the modern faults, according to a new Tectonics study. Credit: Washington Geological Survey.

Earth’s first continents may trace back to subduction 3.5 billion years ago

The northern end of the Cascadia subduction zone, where the Juan de Fuca (JdF) and Explorer (Exp) plates slowly move beneath the North American plate, is gradually shutting down piece by piece, with small pieces of the plate breaking off while the remaining plate continues to subduct until the next tear occurs.
