This week a research ship is retrieving dozens of seismometers that have spent the last year on the ocean floor off the Northwest coast. Earthquake scientists hope the data they're about to get will shed more light on the structure of the offshore Cascadia fault zone. That plate boundary will be the source of the Big One whenever it rips.

The earthquake and tsunami threat to the Northwest from the offshore Cascadia fault was in the news in multiple ways Thursday. Canadian researchers have reconstructed a prehistoric record of great earthquakes on that shared fault. It reconfirms that we're due for another Big One. Coincidentally in Oregon, tsunami preparedness is getting a renewed look.
