Deep Quakes, North Island and Southern Fiji

A pair of very deep moderately strong earthquakes struck the southern Fiji Islands twelve hours apart last night and this morning. A separate pair of deep quakes struck an hour apart under the North Island last night.

The first of the Fiji pair was a magnitude 5.2 earthquake located 220 km south-south-west of Ndoi Island in the southern part of the Fiji group. This quake struck at 10:26 p.m. on Thursday the 7th of February 2008 New Zealand Daylight Time at a depth of 460 km.

A similar-sized quake followed at 10:30 this morning. The magnitude 5.1 quake was located 340 km south-south-west of Ndoi Island at a depth of 500 km.

Last night’s quake in Fiji was preceded by a deep quake under the central North Island. The magnitude 4.6 quake struck at 10:16 p.m. near Taumarunui at a depth of 160 km. This quake was felt at Palmerston North and Porirua. A deeper quake of magnitude 4.4 struck to the west of Taumarunui an hour later at 11:17 p.m. at a depth of 226 km.
