Earthquake Warning: Srinakarin Dam at risk of bursting
Published on January 25, 2006
Structure built on fault line; trembler ‘would cause flooding in 13 provinces’
Three studies have concluded that the Srinakarin Dam in Kanchanaburi is built on a fault line and may burst in a powerful earthquake.
A rupture would cause flooding in 13 provinces, including Bangkok, Thamrong Thawatchaipracha, an engineer who helped build the dam, said yesterday.
He revealed the findings at a seminar on the risk of a disaster at the dam. “Within five hours the flood would arrive in Kanchanaburi’s Muang district,” he said.
Numerous Bangkok districts would then be flooded within 35 hours, including Bangkok Noi, Bang Khunthien, Chom Thong, Phasi Charoen, Rat Burana, Taling Chan and Thon Buri, he said.
Thamrong’s pride in the dam’s construction has been replaced by regret, he said.
“I was confident about the construction’s high standards and ignored warnings the dam was on a fault line,” Thamrong said.
When his team took charge of building the dam he did not consider the possibility of an earthquake in Kanchanaburi, he added.
He became aware of the problem only after the Electricity Generating Authority of Thailand (Egat), now Egat Plc, commissioned three companies from the United States, Sweden and Canada to evaluate the risk an earthquake could pose.
“Their findings were the same,” he said. Each study concluded the province could suffer an earthquake of up to 8.0 on the Richter scale, he said.
The dam is designed to withstand an earthquake of up to 7.5, provided its epicentre is at least 250 kilometres away, Thamrong told the seminar.
After learning about the three studies, he urged Egat to upgrade safety measures at the dam, but has not heard of any being made, he said.
Dr Panya Jarusiri, a geologist at Chulalongkorn University, told the seminar: “We have to improve the early-warning system in Kanchanaburi and prepare an evacuation plan.”
Kwaen Seetathani, a senior Egat executive, said the company would increase safety checks at the dam.
