National Warning #10: NO CHANGE Tsunami – Threat to Marine and Beach Areas
No: 10
Issued 09:00 hours 14 November 2016
The Ministry of Civil Defence & Emergency Management (MCDEM) has issued a tsunami warning (marine and beach threat) from Napier to north of Dunedin,
Cook Straight coastal areas and The Chatham Islands. Please see the attached map for affected areas. The threat for all
other regions has been lifted. All previous threat regions will experience unusually strong currents for some time.
More Detail
Areas under ‘Marine and Beach Threat’ can expect unusually strong currents and unpredictable water flows near the shore.
This means a threat to beach, harbour, estuary and small boat activities. The severity of currents and changing water
flows will vary within a particular coastal area and over the period this warning is in effect.
Current assessments indicate that coastal inundation (flooding of land areas near the shore) is not expected but this
assessment may change.
The first tsunami activity has reached New Zealand. The first wave activity may not be the most significant. Tsunami
activity will continue for several hours and the threat must be regarded as real until this warning is cancelled.
People in Napier to north of Dunedin, Cook Straight coastal areas and The Chatham Islands areas should:
1. Stay out of the water (sea, rivers and estuaries, including boating activities)
2. Stay off beaches and shore areas
3. Do not go sightseeing
4. Share this information with family, neighbours and friends
5. Listen to the radio and/or TV for updates
6. Follow instructions of local civil defence authorities
7. If beach threat is forecasted for your area, take appropriate evasive action
This warning will remain in effect until a cancellation message is issued by MCDEM.
Only messages issued by MCDEM represent the official warning status for New Zealand. PTWC messages do not represent the
official warning status for New Zealand.
Local civil defence authorities will interpret this information for their areas and advise public action.
MCDEM and scientific advisors are continuously monitoring the situation.
Note:
• The wave amplitudes given indicate the largest expected wave activity at any coastal point in the particular
coastal zone and at any time during the entire period this warning is in effect (tsunami activity will vary in a zone
and with time; the first wave activity may also not be the largest).
• The given amplitudes do not include the local tidal or sea state at the time of tsunami activity.
• Local authorities will determine the implication of the expected wave heights for their areas and will decide on
appropriate response actions (e.g. evacuations). Listen or check for this information from your local authority.
