Florence, Oregon, Tsunami Information

Satellite view of Florence, Oregon

As you can tell from the photo above, the city of Florence has miles of beach that face the Pacific Ocean. To help inform residents and those visiting the area, Agrisea has placed on this page all publicly available material about what to do in case a Tsunami comes to Florence.

Visitors should be aware that Florence has a Tsunami Early Warning System of sirens that are tested on the last Friday of every month at 11am. The sirens go off for about a minute and then chimes are sounded at the end of the test. In case of a real Tsunami Alert, the sirens will go off for as long as needed. It is strongly suggested that during a Tsunami Alert, you tune your radio to KCST 106.9 FM.
