The recent 6.8 quake in Burma (Myanmar) was felt in Thailand. It gave the press something to write about, especially in light of the devastation from the preceding quake in Japan. I couldn’t find a history of earthquake magnitudes in Thailand, which probably means the geology of the region has never produced The Big One. That might be the reason earthquake building codes were not established until 2007.
Recent news articles pointed out that more than 2300 buildings in Bangkok are not earthquake safe. This is Thailand, so list is not public. What was made public is that when the government established earthquake building codes it did not assign to any government agency the responsibility for verifying that construction was up to code. The responsibility lies in the hands of the builders. Whether the 2300 includes any new buildings that should have constructed to code has also not been made public.
