National Warning: Tsunami Threat CANCELLED
National Warning: Tsunami Threat to Beach and Marine Areas CANCELLED
Issued at 11:30, 9 September 2017 by MCDEM.
The Ministry of Civil Defence & Emergency Management (MCDEM) has cancelled the National Warning Tsunami Threat to Beach and Marine in place for Chatham Islands, Pegasus Bay, Northern Coasts of Hawke's Bay and East Cape.
Based on all available data, the tsunami beach and marine threat for the above areas has now passed.
The largest wave amplitude of 35-40cm was recorded at the Chatham Islands. Observations from tidal gauges around other sites of New Zealand have shown that maximum wave amplitudes of 15-25cm.
We don't expect any further significantly larger waves to
occur for the above areas. However, there is still the
possibility of waves less than 20cm, and coastal areas will
likely experience unusual, strong currents and surges
lasting for several more
hours.
