Another powerful earthquake strikes Fiji – more intense seismic activity could occur in the region this year
A powerful quake measuring up to 7.3 Mw struck Fiji at 17.212°S, 178.413°E or about 100 km north of the capital, Suva and at a depth of 585 km on Monday, November 09, 2009 at 10:45 UTC.
The mainshock was followed by at least one aftershock measuring 5.3 Mw.
On August 19, 2009 FEWW Moderators posted the following entry:
New Round of Geo-Assualt at Kermadec Trench
Following the powerful 7.8 magnitude earthquake that struck the tip of the Fiordland, South island, New Zealand, followed by a large cluster of aftershocks, another round of geo-assault appears to be gearing up at the southern end of the Kermadec trench.
The Fiordland quakes occurred as a result of a large reverse faulting motion caused by the subduction of the Australian subplate under the Pacific plate, on which Fiordland rests, in Puysegur Trench, at the Alpine Fault.
The new wave of earthquakes would instead be caused by the ‘mirror image’ action, with Pacific plate subducting beneath the Australian protoplate.
A magnitude 6.3 earthquake that struck south of the Fiji Islands on August 18, 2009 at 21:21 UTC may herald a new round of intense [and unprecedented] seismic activity at Kermadec Trench to the north, NE, and East of the North Island, as well as the north, NE, and east of the South Island, New Zealand.
