Tsunami Warning (3) - Solomon Islands / Fiji

Tsunami bulletin number 003 issued at 2239z 01 apr 2007

Areas to the north of the solomon islands should not be significantly affected. A tsunami warning is now also in effect for Kermadec Islands in New Zealand. Measurements or reports of tsunami wave activity:
Honiara 15cm zero-to-peak observed at 21:37 gmt


Evaluation

Sea level readings indicate a tsunami was generated. It may have been destructive along coasts near the earthquake epicenter and could also be a threat to more distant coasts. Authorities should take appropriate action in response to this possibility. This center will continue to monitor sea level data to determine the
extent and severity of the threat.

For all 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.

Estimated initial tsunami wave arrival times. Actual arrival times May differ and the initial wave may not be the largest. The time Between successive tsunami waves can be five minutes to one hour. Read arrival times at PTWC here
