A new seismic study of Singapore could guide urban growth and renewable energy development in the coastal city nation, where 5.6 million residents live within an area of 734 square kilometers.
A new seismic study of Singapore could guide urban growth and renewable energy development in the coastal city nation, where 5.6 million residents live within an area of 734 square kilometers.
The study, published in Seismological Research Letters, identifies areas with increased risk of ground shaking and a possible reservoir for geothermal energy production, as well as a glimpse at Singapore’s tectonic history.
Jiayuan Yao of China University for Geosciences and colleagues analyzed teleseismic data captured by a few permanent seismic stations and a nodal seismic array deployed in 2019 around the city. Their results provide the first detailed look at the top-kilometer depth of sediment.
“These data are invaluable for assessing potential seismic hazards,” said Yao. “Our findings suggest that areas with soft sediments, especially the reclaimed land in eastern Singapore, are likely to experience higher seismic ground motion amplification.”
