tsunami sirens going off in Honolulu!!!

edit to clarify: That wasn't sarcasm.

Hilo got whacked by a tsunami from the 1960 Chilean earthquake, but that was a 9.5. The tsunami from the M 9.2 Alaskan earthquake brought a 12-foot high tsunami to Hilo. But hopefully nothing will come from this earthquake.

Hopefully won't be too big

But more details would be nice.

"visible tsunami, headed in right now"

The "wave" that hit British Columbia was 0.3ft high. And this is the projection by NOAA...

They've switched from a "warning" to an "advisory." Any waves they've talked about have been measured in centimeters.

Not sure what's going on in Hawaii.

"David McCormack, Director of Hazards Information Services for the NRC, said that this is a "small tsunami," measuring at last tally 43 centimetres from peak to peak, or 21 cm from baseline to peak.

"That's a wave smaller than what you would see in your bathtub, " he said, adding that such waves in confined spaces like ports can still cause a lot of damage, or can pick up steam as they travel."


And yet the NWS Pacific Tsunami Warning Center has this to say:

Wave height will grow exponentially as it gets closer to land.

Even 0.8 feet isn't much to write home about. It'll knock a few boats around.

I wish they would talk English


1 Meters (m) = 3.2808398950131 Feet (ft)

1 mile = 1.6093440km

1in = 2.5400000cm

earthquake did not get a tidal wave, just maybe higher regular waves. CTV News.
