Is Bangkok safe?

Bangkok is located close enough to fault lines to cause concern for earthquake damage, but expert disagree on how bad it would be.
2,700 city buildings at earthquake risk
Even moderate tremor at fault lines poses danger
Earthquake preparedness is a must for Bangkok as the capital is not far from active fault lines where even a moderate quake could send strong shock waves to the city, seismologists have warned.
City Hall has issued a warning that about 2,700 buildings in the capital could be damaged by an earthquake.
Bangkok is less than 200 kilometres from Kanchanaburi, home to the Chedi Sam Ong fault line, and about 800km from Chiang Mai, where the Mae Ta and Mae Chan fault lines are located.
The Chedi Sam Ong, Mae Ta, and Mae Chan are among 13 active fault lines in Thailand covering 22 provinces.
Studies showed there is a high possibility that a powerful earthquake of 6-7 magnitude will occur along the fault lines in Kanchanaburi and Chiang Mai provinces, Pennung Warnitchai, a seismologist from the Asian Institute of Technology, said yesterday.
His comment followed the 6.8-magnitude earthquake in northern Burma that killed at least 75 people, including a Thai villager in Chiang Rai, on Thursday.
The quake sent shock waves that could be felt in several parts of Thailand, including Bangkok.
Quakes in Kanchanaburi or Chiang Mai would not only cause severe damage to the two provinces but also to Bangkok, Mr Pennung said.
"We will see severe damage to buildings and other structures in Bangkok," the seismologist said.
However, Lertsin Raksaskulwong, director of the Mineral Resources Department's environmental geology and geohazard bureau, disagreed.
He said earthquake damage in Bangkok would not be serious.
"There won't be total building collapse. People will only feel the buildings shaking, like many people in high-rises felt on Thursday," he said.
Surachai Ponpattarakul, a senior expert at the Department of Public Works and Town and Country Planning, said the issue of buildings' resistance to earthquakes had become a major concern following frequent natural disasters.
The agency has been drafting a regulation to help owners of buildings constructed before the enforcement of the 2007 Building Control Act improve their buildings' structures to ensure they are earthquake-resistant.
The Building Control Act stipulates that buildings 23 metres or higher and buildings covering more than 10,000 square metres must have structures that can resist an earthquake of at least 5 on the Richter scale.
Deputy Bangkok Governor Pornthep Techapaiboon said initial inspections of 12 high-rise buildings in Bangkok after Thursday's earthquake found none had been damaged, but a close watch would be kept on the situation.
