A 7.9 Earthquake happened in the Philippines about one half hour ago. ( They just now downgraded it to a 7.6 - which is normal for USGS) I am leaving the 7.9 up due to that being the original magnitude listed.

Here is the buoy data info, to watch for the buoy movements of water.
Here is a link to a post I did 3 years ago, but I updated it on 3/11/11- adding more webcams of the Pacific where I have many webcams linked throughout the Pacific - I don't know if they are all still on, but here is the link anyway for watching for tsunamis on the beaches of the Pacific.
There is a difference of 60 feet in the water changes in seconds off the coast of Japan.
Here is the data graph off the buoy data info linked above:
