Tsunami 2004 Colombo, 20 minutes nonstop video. 2004年海啸科伦坡20

TRY 480p, artifacts in 720p !!. Probably the longest Tsunami video showing the oceans movements in relation to the shoreline in Wellawatte, Colombo, Srilanka. Luckily Colombo's coast is over 4 metres amsl so wasn't too affected by my estimate of the 3.5 metre swell of the ocean
