Probably near the edge of the wave or just a fake. For one thing, the tsunami sucks a lot of water out to sea before it reaches shore and this beach did not look like that. Secondly, if the cameraman really was in the path of the tsunami, a short jog to higher ground would not have been enough to survive. Think about it. If over 100,000 people drowned from the waves, it would be about 10-20 times as bad as depicted here.
I suspect this is either a spoof or someone caught a weak edge of the wave in some area a long way from the epicenter.
