I don't think so.

As far as I know, the only ocean with detection is the Pacific, and those monitors tend to be between Alaska and Hawaii.

These are there only because of modern waves that have affected Hawaii, like those after the Alaska quake. Since nothing significant has happened in modern times in the Atlantic, it's rather hard to get funding or to convince an ignorant public of the need to invest in warning systems based on geologic evidence.

But here'san article in the New York TImes that's pretty good.

Did you know the wave was detected by tidal gauges along the Atlantic coast?? (also from the times, reg. required.)

A tide gauge at Atlantic City recorded the passage of a "train" of waves, just under nine inches from crest to trough, 32 hours after the earthquake struck off Sumatra's west coast on Dec. 26, said Dr. Alexander B. Rabinovich of the Canadian Institute of Ocean Sciences in Sidney, British Columbia. A gauge at Port Canaveral, Fla., recorded 13.4-inch waves 24 minutes later.
