Emergency services officials are warning people the best tsunami warning will come from nature itself after the third false tsunami siren sounded in the coastal town of Whitianga last week.

On July 5 Whitianga in the Coromandel experienced its third false tsunami alarm and Thames Valley Emergency Operating Area Manager Gary Talbot says imagine a warning siren that sounds with a low frequency pulse that shunts your whole town sideways.

That is what a real tsunami would be like.

Gary says people are at greater risk if they are close to the beach and experience any or all of the following nature warning signs:

- Feel a strong earthquake.

-Feel a weak rolling earthquake for a minute or more.

-See an unusual and sudden sea level fall or rise.

-Hear the sea making loud and unusual noises.

'If you feel, see or hear any of these warning signs, evacuate immediately to high ground or move inland as far as possible.

'The fire siren may also sound continuously for 10 minutes or more.”

Recently, a new possible tsunami warning system was tested in Tauranga.
