 10 Meter Water Displacement (30 Foot Tall WAVE!)

According to the National Data Buoy Center, the earthquake caused a 10 Meter Water Displacement; the earth moved so much that it generated a 30 FOOT wave which is now heading toward Hawaii and the US/CANADA west Coasts.

 

Data Buoy #46410 off Alaska Coast

 

It's like the whole north part of the pacific plate shifted, that the top corner went up 10 meters, then down 10 meters, all over the course of 15 seconds. Amazing.

At the same about 40 miles southwest, the shift was only about 2 meters... but imagine along that 400 mile line, the displacement of that much water... That's gonna cause some waves that could travel all day.

 Tsunami Buoys throughout the north Pacific Ocean are ALERTING to the incoming wave! ! ! 

The 17 Second graphic below shows the magnitude of the earthquake and the ALERTING TSUNAMI BUOYS

 

 

 Here is the Official Tsunami Wave Arrival-time chart from the Pacific Tsunami Warning Center:

 

EVACUATIONS ORDERED IN ALASKA, PARTS OF CANADA

 

Environment Canada issued a tsunami warning on Tuesday morning that stretched all along B.C.’s coast, from Greater Victoria north to Haida Gwaii and beyond.

“If you are in a coastal area that is at risk, you should move to high ground now and heed further instruction from local authorities,” the warning said.

The agency warned that a tsunami is a “series of waves,” and that the “first wave may not be the largest.”
