Email received by CDEM Duty Officer re “National Warning#14: NO CHANGE Tsunami – Threat to
Marine and Beach Areas” advising “MCDEM has issued a tsunami warning (marine and beach
threat) from Wellington to Banks Peninsula. The threat for all other regions has been lifted. All
previous threat regions may experience unusually strong and unpredictable currents for some
time. 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 in land areas near the shore) is not expected but this
assessment may change. People in Wellington to Banks Peninsula should: stay out of the water,
stay off beaches, do not go sightseeing, follow instructions of local civil defence authorities, if
beach threat is forecasted for your area, take appropriate evasive action. Warning will remain in
effect until a cancellation message is issued by MCDEM. Local civil defence authorities will
interpret this information for their areas and advise public action.
