In 1700, a massive earthquake struck the west coast of North America, but a lack of local documentation has made studying this historic event challenging. Now, researchers from the University of Pennsylvania have helped unlock this geological mystery using a fossil-based technique. Their work provides a finer-grained portrait of this earthquake and the changes in coastal land level it produced, enabling modelers to better prepare for future events.
