First of a three-picture sequence. "Tourists run for their lives as the first of six tsunamis starts to roll towards Hat Rai Lay Beach, near Krabi in southern Thailand. One woman runs towards the waves." From AFP, via the Sydney Morning Herald.
There are a lot of pictures tagged with tsunami on Flickr.
This sequence of three pictures is the most ... amazing? ... frightening?
To follow the sequence look to the right of the large picture. There is a thumbnail with a link above it labelled "next in set >>".
