Those buoys are DART system for Tsunami detection.

PS: Water column is another way to express depth.

At least one of the surges was more than 30 meters - so that would be a really BIG WHEEEEE!!!!!!! 
This is the water column height, not wave height so unfortunately it wouldn't even be notice at sea, it's more like the tide change but since you are in open ocean, you don't have any reference to measure it by. Without the GPS on the buoy, it wouldn't notice it either. The flashing buoy's in the video are listed as Tsunami warning buoys activated after the earthquake.
Interesting data points and could be an issue if the height carries over to shore where it could turn into a Tsunami. And while the data points are interesting without a historical reference to see if this is normal or directly related to the earthquake its hard to understand what is going on.

Here is a nearby WAVE buoy and weather with a camera too.

Wave height was 7.9 feet.
Waves are surface things. Water Column is a depth thing.
5000+ meters is a few miles of ocean depth being effected.
Tsunami are not a major problem unless they hit shore line.
Why?
The lower part of the "wave" is pushed upwards by land. In deep ocean, not so much.
