The first video--the one inside the building--is from a Norwegian website.

More information on the people seen in the water down below:

A Norwegian and a Swede fought feverishly against the mass of water to save an older man. See the video.

Swede Fredrik was thoughtful this evening. Together with Norwegian Olivier, he may have saved a human life in the frothing water wave that poured in over Phuket yesterday.

"We tried to drag an elderly English couple out of the water. But then the cement fence broke that they were clinging to. We managed to find the man afterwards, but we haven't seen the woman", said Fredrik to Dagbladet at the Bangkok Hospital in Phuket.

He has just been to visit the elderly Englishman that he rescued.
The man is in a coma at the hospital.

The Norwegian who helped him has not been seen since. Everything is chaos in Phuket right now.

Another Swede filmed the wave when the two men tried their best with the rescue attempt. Thanks to that, you can see for yourself how strong the mass of water was when the second wave come in.

Most people thought that after the first wave, everything was over, and that the water had settled down.

They were wrong.

"I ran down to see if I could help anyone. I saw the first wave come from the window in my hotel room. When the second wave came in, I didn't have chance to get away " he said to Dagbladet.

Something which may have saved a life.

In the slide show in the link, a man is also seen struggling in the water. Someone in the comments says this man was rescued, but it's unclear.
