Hastings Earthquake

A shallow moderately strong earthquake struck near Hastings in Hawkes Bay late last evening. The magnitude 5.9 earthquake was located 10 km south-west of Hastings at a depth of 30 km.

The earthquake, which struck at 11:25 p.m. on Monday August 25th 2008 was strongly felt in the eastern part of the North Island from Hawke’s Bay to Gisborne, with initial reports from as far away as Wanganui and Wellington.

Damage has been reported from several locations in Hawke’s Bay where residents report items thrown from shelves and cupboards, pictures off walls and broken glassware. Electricity supplies, which were tripped in some areas, have been restored.

Early reports from overseas agencies which have limited coverage for onshore quakes in New Zealand report the quake at a lower magnitude. The U.S. Geological Survey reports the quake at magnitude 5.4 located 50 km west-south-west of Napier at a depth of 10 +/- 12 km. Geoscience Australia report the quake as magnitude 5.6 at a depth of 33 km. The density of GeoNet’s network of instruments would have given a better value for the event.

An aftershock of magnitude 3.5, slightly deeper at 40 km, struck 10 minutes after the main quake.
