Pacific Tsunami Depictions
Last night, an 8.8 magnitude quake hit off the coast of Chile (you can download the shakemap for use in Depiction here). There is now a tsunami warning in effect for much of the Pacific. Much of Hawaii, in particular, is evacuating, as waves are expected to start hitting in just a couple hours.
I’ve quickly built a depiction with possible tsunami inundation zones for Hilo Bay, where the waves are expected to hit first. I’m hoping to build others as the day goes on.

Thank you for the interesting graphic. Your second link says “Hilo” but it is for Honolulu.
Would it possible to post a graphic for Kahului Bay on Maui?

I’ve fixed the text, and I’ll get to work on Kahului Bay right now. Thanks!

Mahalo for working on the Kahului map. I am originally from Maui.
I am watching the tsunami web page (http://hitsunami.info/) and one oceanographer said that there are three “resonant” bays that make tsunami stronger: Hilo, Haleiwa, and Kahului.

Incredible work, Timothy. Thanks again!

Correction to my post 3: Hilo, Hanalei, and Kahului and resonant harbors. Sorry about that.

Our camping, hostel, and guesthouse are just east of Hilo, barely above sea level. Really nice work. However, I believe we were not told as much as the oceanographers knew full well – that there was nothing as far as a tsunami of any consequence. The very large earthquake had most all of its energy dissipated in solid earth, and they have data coming in from all parts of the Pacific that would have shown that.
We were worried about our gardens, hostel, guesthouse, and campground as they are all just on the outskirts of Hilo and well within a tsunami’s vertical reach. Thanks for your work

Although not strictly weather related,rogue wave events also known as extreme waves are towering and spontaneous ocean waves that occur far out at sea, and are a danger even to tankers.In oceanography, they are technically defined as waves whose height is more than twice the significant wave height (SWH), this measurement is dependant on observing a series of waves to determine the largest third of waves. Therefore rogue waves are not necessarily the largest waves found at sea; they are, rather, large waves for a given sea state.
