The first “Tsunami Advisory Alerts” started lighting up my phone and email about 5 am this morning. WHAT?!?
The north Oregon Coast – in fact the entire Pacific coast from the Alaska to Mexico was under a Tsunami Advisory after at cataclysmic underwater volcano eruption near the island of Tonga in the South Pacific. The eruption sent shock waves, sound waves and energy that registered on seismometers in the Cascades! I’ve been posting hourly updates since early this morning. The tsunami waves that hit Hawaii were 3+ feet, and the Pacific Coast saw heights from 1 to 3 feet. There was no damage reported … the tsunami advisory was lifted at about 5 pm. As Dave Dillon noted, “The tsunami wasn’t very photogenic from Manzanita beach, but the image is of the spectators.”
This was a “long-distance” tsunami event which fortunately only resulted in and “advisory” – stay off beaches; a “near-shore” earthquake along the Cascadia subduction zone would result in an immediate evacuation. A reminder about the need for emergency preparedness (see below for more about 4-weeks ready.) Many reported “not getting any alerts or warning” and also the inevitable – where are the sirens? Tillamook County decommissioned it’s siren system more than a decade ago. The best way to receive information about emergencies in your area (or an area you are visiting) is to sign up for Nixle alerts – https://www.nixle.com/
Take this event as a friendly reminder to be “four weeks ready”. This means your household has enough food, water, medical supplies, sanitation supplies, and other life-sustaining resources to meet your specific needs for at least four weeks. In a major disaster such as a Cascadia Subduction Zone earthquake; supply chain, responders, and transportation would be disrupted. This means our communities need to be prepared to take care of each other until assistance is available.
