Wow, so it was quite close to Samui and Ko Phang Ghan!

But no Tidalwave in sight!

That is a surprise to be so near to Bangkok. I was just talking to a friend of mine who stayed in Bangkok in the mid 70's and he said he experienced an earthquake when he was there. Looking at the little tiny sticks they call building columns in Bangkok, and looking at the building columns in Tokyo and San Francisco airports (buildings that are not nearly as tall) does not leave me with good feelings of safety should any earthquake hit.

Can anyone provide a link to a website that shows fault lines in the area?

I wonder why the Meteorological Department said it was in Burma. I felt it in Pattaya. For sure! I was up at 4:12 and felt a single bump or shudder. I've lived in California, and in Hawaii and have felt small episodes like this many times. If it was in Burma I doubt that I would have felt anything.

If you look around the USGS sites, they say the accuracy of their locations is around +/- 15 Kilometers or so. That would still keep it in the Gulf of Thailand.

Do you think there could be a reason that we would be told it was in Burma? Tourism? Failure to alert anyone about the possibility of a Tsunami? Or is it the superiority of the Thai Seismographic equipment that accounts for the disparity?

I agree with John K about the buildings here -- Scary! If there's one kind of building you can't build in SF, it's a brick building. The buildings in BKK would turn to rubble in seconds if a major trembler hit.

I've been looking for a long time for fault maps for SE Asia, but haven't found anything informative as yet.

Thanks for the tip, here is a pdf file from that. I noted that there is a fault line that runs very near Bangkok, looks like one runs almost under the new airport. Not very comforting.
