M8.7 quake near Sumatra
UPDATE by Dave – Looks like this earthquake isn’t an aftershock after all. It’s been upgraded to a M8.7 by the USGS. It also appears that this quake relates to the information from this earlier post. CNN is also reporting a “small tsunami” was detected. A Wikipedia article on the 2005 Sumatran Earthquake has been created. This is also the 8th largest earthquake since 1900.
(Original Entry) A M8.2 aftershock (a large quake by itself) to the December 26th quake struck near Sumatra earlier today at roughly 11PM local time. Authorities in Sri Lanka and Thailand have ordered evacuations. The Pacific Tsunami Warning Center issued this bulletin.
THIS CENTER DOES NOT HAVE SEA LEVEL GAUGES OUTSIDE THE PACIFIC SO WILL NOT BE ABLE TO DETECT OR MEASURE A TSUNAMI IF ONE WAS GENERATED. AUTHORITIES CAN ASSUME THE DANGER HAS PASSED IF NO TSUNAMI WAVES ARE OBSERVED IN THE REGION NEAR THE EPICENTER WITHIN THREE HOURS OF THE EARTHQUAKE.
