A 5.0-magnitude earthquake shook New Zealand's central North Island, but there were no immediate reports of injuries or damages, police said.The moderate temblor, with an epicentre some 10 km northeast of the tourist town of Rotorua, was located 170 km beneath the earth's surface, seismology agency GNS Science reported. Rotorua police senior sergeant Scott Fraser said nobody had reported feeling the quake, which struck at 11:56 a.m. local time (2256 GMT Wednesday). A quake of 4.9-magnitude struck under the seabed off North Island's east coast Wednesday, but without causing injury or damage. New Zealand sits above an area of the earth's crust where the Pacific and Australian tectonic plates are colliding and records more than 14,000 earthquakes a year, but only about 150 are felt by residents. Fewer than 10 a year do any damage.
