Taupo Earthquake

A magnitude 5.8 earthquake struck near Lake Taupo early this afternoon.

The quake, which struck at 1:21 p.m. on Monday the 1st of September 2008, was located 10 km south-east of Turangi, 40 km north-east of Waiouru, 50 km south of Taupo at a depth of 80 km.

Unlike last Monday’s magnitude 5.9 quake near Hastings, today’s event was 50 km deeper, lessening the chance of serious damage. It is estimated that residents of parts of the central North Island and Hawke’s Bay may have suffered some breakages of glassware and ornaments, and some objects may have moved during the shaking. Further away, doors and windows would have been heard to rattle, but little damage to household contents is expected.

The U.S. Geological Survey reports the earthquake as being located south-west of Turangi, closer to Mt. Ngauruhoe than GeoNet’s analysis. They have analysed the quake as magnitude 5.2 at the shallower depth of 66 km.

Within an hour of the quake, 264 reports of the earthquake had been filed with GeoNet from as far south as Wellington, Marlborough and Christchurch. Strong shaking was reported at Bridge Pa, Crownthorpe, Feilding, Flaxmere, Marewa, and Tamatea.

A cluster of six other earthquakes reported within 20 km of Taupo township during August have all been very shallow events. The quakes, with magnitudes between 2.3 and 3.6 have ranged between 2 and 5 km in depth.
