Tremors shook several parts of Singapore on Thursday following aftershocks in the Indonesian island of Sumatra, prompting hundreds of nervous residents to call the civil defence force.
Engineers from the Land Transport Authority (LTA) were inspecting all buildings where tremors were felt either late Wednesday or Thursday.
They were also checking for signs of structural damage.
The public was assured that buildings in the city-state "are designed with an in-built strength and are unlikely to collapse because of tremors caused by distant earthquakes," said LTA chief engineer Paul Fok.
The road and rail infrastructure is also designed to withstand such tremors.
Thousands of people dashed out of office buildings and their homes Wednesday night when the Sumatra earthquake struck 750 kilometres away, resulting in tremors in various parts of Singapore, including the central business district.
Among them was teacher Olivia Lim who grabbed her three children and went down 14 flights of stairs from her apartment.
No damage, injuries or law and order problems were reported. dpa ry jh
