:eek: 8.8 is a HUGE earthquake!

[Lily]

Yeah, very big. It looks like the Hawaiian Islands may get some pretty big waves in five or six hours.

The US mainland had, to date, one tsunami in recorded history, in 1964 as a result of an 8.6 earthquake in Alaska. While all the California and lower Oregon coast received damage, Crescent City, California bore the brunt, with a series of four waves. The was last 21' in height, which sucked the harbor dry and then destroyed 30 blocks of the city's waterfront.

After the event Crescent City implemented and still has mandatory tsunami drills.

Warning sirens just went off in Hawaii, signaling evacuations.

Here is the latest advisory for the west coast and California. Waves up to 2.6 ft above normal at Malibu, 3.3 ft in Santa Monica. Probably not a good day to be on the beaches.

First waves are expected to hit at 4:19PM EST.

[Americano]

Ex[expected to be dangerous when it hits Hawaii, but not catastrophic.

It looks like everyone dodged the bullet, thankfully. The tsunami warnings have now been canceled for all countries.

So what happened? Did the waves just miss Hawaii? :ummm:

No, they came in... about three of them, I think. They were just nothing to speak of, pretty small. Someone likened them to the tide going in and out, but in a matter of minutes instead of hours.

So Tsunami forecasting is as accurate as normal weather forecasting... 50/50 at best! :lol:

Yeah, I don't think they have a good handle on it, yet. Japan actually got higher waves that Hawaii. Has something to do with the topography of the ocean floor. :shrug:

It's not like tsunamis are common occurrences offering frequent case studies. Scientists are still using models dependent on after occurrence measurements to forecast path and speed, speed being dependent on ocean floor topography.

Michael? What he said. :lol:
