The quake was the second powerful quake occurring along the South Solomon Trench since 20:14UTC on Saturday, and the latest event in the ongoing episode of intense seismicity on or near the boundary between the Australia and Pacific plates.
FIRE-EARTH Earthquake Forecast
A detailed FIRE-EARTH Earthquake Forecast appeared in the Bulletin NO. 84, which was released on April 12.
The next FIRE-EARTH Earthquake Forecast will be issued together with the April 13 Bulletin, later today.

Tsunami Evaluation
PACIFIC TSUNAMI WARNING CENTER/NOAA/NWS ISSUED AT 13:18UTC 13 APR 2014
It is not known that a tsunami was generated. This warning is based only on the earthquake evaluation. An earthquake of this size has the potential to generate a destructive tsunami that can strike coastlines in the region near the epicenter within minutes to hours. Authorities in the region should take appropriate action in response to this possibility. This center will continue to monitor sea level gauges nearest the region and report if any tsunami wave activity is observed. The warning will not expand to other areas of the Pacific unless additional data are received to warrant such an expansion.
Estimated initial tsunami wave arrival times at forecast points within the warning and watch areas are given below. Actual arrival times may differ and the initial wave may not be the largest. a tsunami is a series of waves and the time between successive waves can be five minutes to one hour.

Centered at 11.315°S, 162.211°E the quake struck at a depth of about 29.3km (18.2mi), said USGS/EHP.
The powerful shock occurred along the South Solomon Trench and was the latest event in an episode of intense seismicity on or near the boundary between the Australia and Pacific plates.
The earthquake was downgraded from an initial magnitude 7.8 to 7.6Mw
The quake was followed by about a dozen significant aftershocks, as of posting.
Tsunami Evaluation
Initially, the PACIFIC TSUNAMI WARNING CENTER (PTWC) issued an expanding tsunami warning and watch for parts of the pacific located close to the earthquake.
In a latest bulletin, ISSUED AT 21:36UTC on 12 APR 2014, PTWC said:
SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER. FOR THOSE AREAS – WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

Seismotectonics of the Eastern Margin of the Australia Plate
Excerpts from the Tectonic Summary [sourced from USGS]
Since 1900 there have been 15 M7.5+ earthquakes recorded near New Zealand. Nine of these, and the four largest, occurred along or near the Macquarie Ridge, including the 1989 M8.2 event on the ridge itself, and the 2004 M8.1 event 200 km to the west of the plate boundary, reflecting intraplate deformation. The largest recorded earthquake in New Zealand itself was the 1931 M7.8 Hawke’s Bay earthquake, which killed 256 people.
Large earthquakes are common along the North New Hebrides trench and have mechanisms associated with subduction tectonics, though occasional strike slip earthquakes occur near the subduction of the D’Entrecasteaux ridge. Within the subduction zone 34 M7.5+ earthquakes have been recorded since 1900. On October 7, 2009, a large interplate thrust fault earthquake (M7.6) in the northern North New Hebrides subduction zone was followed 15 minutes later by an even larger interplate event (M7.8) 60 km to the north. It is likely that the first event triggered the second of the so-called earthquake “doublet”.
