Strong Quake, Vanuatu

A strong earthquake struck Vanuatu this evening, New Zealand time.

Friday 2nd July 2010

A magnitude 6.4 earthquake struck 220 km north-north-west of Luganville, Espiritu Santo at 6:04 p.m. this evening, New Zealand time. The shallow quake, centred 330 km south of Lata in the Santa Cruz Islands (495 km north-north-west of the Vanuatu capital, Port Vila) was 35 km deep according to the U.S. Geological Survey.

Geoscience Australia reports the event as magnitude 6.8 at a depth of 80 km. It estimates that the quake would have caused damage within 80 km of the epicentre, which includes the Torres islands, and would have been felt up to 1000 km away.

The Pacific Tsunami Warning Centre issued a bulletin for the event at 6:14 p.m. reporting the earthquake as magnitude 6.7 at a depth of 66 km. It advised that, based on historical data, a widespread tsunami threat does not exist as a result of the quake.

This evening’s quake is probably an aftershock of the magnitude 7.2 earthquake that struck 215 km north-north-west of Luganville early on the morning of the 28th of May, New Zealand time.
