A moderate earthquake has rattled Trinidad & Tobago, causing some alarm but no reported damage or injuries.

The US Geological Survey says the magnitude-4.8 quake struck early Sunday and was centred some 81 kilometres northeast of Roxborough, an eastern town on the tourism-dependent island of Tobago. It was also felt on the Caribbean country of Barbados.

Its epicentre was about 46 kilometres below the surface.

In Tobago, police said they received calls from some jittery residents who lingered outside after the quake.
