Abstract
Analysis of earthquakes in the Cascadia subduction zone, located along the Pacific coast of North America, was undertaken through two radiocarbon dating procedures and the use of several plant fossils. The magnitude of earthquakes was calculated through the study of the length of the fault rupture that occurred in prehistoric times. Results show that the region experienced its last rupture or series of ruptures, which extended around 55 km.,in the 16th century.
