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.
