7.9 Earthquake Philippines, only 20 miles deep. Tsunami Warning in effect for the Pacific - Information and Links provided to Buoys - Warning - Quake Info and Webcams in Pacific


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:

  1. Our "loco" paper never mentioned this earthquake. Even though we hane a large amount of Philipinos here and are probably in the path of a generated tsumani.

    I found that very strange indeed!
