Monday August 10th 2009
A magnitude 6.6 earthquake struck the Santa Cruz Islands this afternoon at 4:07 p.m., New Zealand Standard Time. The quake was located 100 km south-south-east of Lata at a depth of 43 km according to the U.S. Geological Survey.
Geoscience Australia reports the quake as magnitude 6.6 at the shallower depth of 19 km. They estimate the quake would have caused damage within about 70 km of the epicentre, and would have been felt up to 800 km away.
The Pacific Tsunami Warning Centre issued a bulletin for the event at 4:17 p.m. NZST, advising that a destructive widespread tsunami threat did not exist. However the quake was of the type that could have generated a wave that was destructive to coasts within 100 km of the epicentre.
An aftershock of magnitude 5.0, located 90 km south-south-east of Lata at a depth of 46 km, was recorded at 5:28 p.m.
