Update 3 - Tsunami passes, warning downgraded

A barely detectable tsunami wave has been recorded in Northland after today’s large earthquake off Samoa but appears to have had little or no local impact.

Civil Defence officials have now downgraded a national tsunami warning for New Zealand issued in the wake of this morning’s 8.3 magnitude earthquake off Samoa.

Clive Manley, Group Controller for the Northland Civil Defence Emergency Management (CDEM) Group, says a tsunami wave – so small it could barely be detected - was recorded at various spots along Northland’s east coast from about 11.15am, coinciding with the low tide locally.

At this stage, Northland officials have no reports of any damage but although the official tsunami warning has now been downgraded, are advising Northlanders in low lying areas to continue a precautionary approach for the rest of the day.

Mr Manley says with tsunami, the first wave is sometimes not the largest. “Other waves will follow, although they’re not expected to pose any real problems in Northland.”

“However, as a precaution, we’re recommending those in low lying coastal areas remain vigilant and everyone else avoid unnecessary travel to these areas. The potential threat of strong currents remains and we also suggest recreational boaties stay off the water at this stage.”

He says although Civil Defence, local authority, police, fire, ambulance and health officials will continue to maintain a watching brief throughout the day, they will only release new information if necessary.

He says today’s tsunami warning serves as a reminder to the public to ensure they are adequately prepared for natural disasters. More information is available from the Ministry of Civil Defence and Emergency Management website: www.getthru.govt.nz
