Written by on February 27, 2010

This is a waiheke Radio tsunami warning bulletin. A tsunami was generated from the 8.8 magnitude quake in Chile yesterday.

The Onetangi Beach Races are postponed until March 14. People are advised to saty off all Waiheke beaches.

Civil Defence have assessed that a tsunmai threat exists for New Zealand.  The first wave to arrive in New Zealand this morning. The first wave may arrive later and may not be the largest. Strong currents and unusual tidal effects may continue for several hours.

Scientific advice is that a marine threat (i.e. threat to beach and small boats corresponding to wave heights less than 1 metre) exists for the entire east coasts of the North and South Islands . 

Wave height refers to maximum water level relevant to the normal sea level at the beach. This does not take tides into account. Based on historical events it is expected that the greatest wave heights will occur between 6 and 12 hours after the initial arrivals.

The National Crisis Management Centre in Wellington has been activated. The Ministry of Civil Defence & Emergency Management (MCDEM) and scientific advisors are closely monitoring the situation.

People in coastal areas should:

   1. Stay off beaches
   2. Stay out of the water (sea, rivers and estuaries, including boating activities)
   3. Share this information with family, neighbours and friends
   4. Listen to the radio and/or TV for updates
   5. Follow instructions of your local Civil Defence authorities

The Onetangi Beach Races are postponed until March 14.
