"These folks appear to be way too casual about the whole thing."
Thats what I was thinking. If it was me I believe I would be trying to climb on the roof instead of taking pictures.
Last night I was hearing accounts on TV and one guy said he ran into his hotel room to look for his camera before the wave hit. He ran back outside just in time to grab his kid and start running before they were swept into a Mangrove swamp. Luckily he survived but I don't think cameras would be my first thought on seeing a tsunami bearing down on my family. Perhaps it is just me?
They didn't know what it was.
