National Warning: Tsunami Threat to New Zealand
Update: Tsunami confirmed
________________________________________
No: 05
________________________________________
Issued at 04:07 hours on 28 February 2010.

Issued by the Ministry of Civil Defence & Emergency Management (MCDEM).

A tsunami warning is in effect for New Zealand:
The tsunami warning will remain in effect until a cancellation message is issued by MCDEM.
________________________________________
An earthquake has occurred with these parameters:
Origin time: 0634Z 27 FEB 2010
NZ time: 1934 NZDT 27 FEB 2010
Co-ordinates: 36.1 SOUTH 72.6 WEST
Depth: 55 KM
Location: NEAR COAST OF CENTRAL CHILE
Magnitude: 8.8
The above magnitude is provisional and may be increased or decreased as more seismic data becomes available.

________________________________________
Summary:

At this stage our threat assessment remains unchanged.

The Pacific Tsunami Warning Centre (PTWC) has issued a Tsunami Warning in response to the above earthquake.

Only messages issued by MCDEM represent the official warning status for New Zealand. Local civil defence authorities may supplement these messages by applying local threat assessments.

Confirmation has been received that a tsunami was generated. A wave measuring 2.34 metres was measured at Talcahuano, Chile and 0.35 metres at Easter Island, Chile.

The first wave to arrive to New Zealand will be in the areas around Chatham Islands (Waitangi) at approximately 07:05 NZDT, Sunday 28 February 2010. The first wave may arrive later and may not be the largest. Strong currents and unusual tidal effects may continue for several hours.

Based on preliminary modelling and comparison with historical events the interpretation of the Tsunami Experts Panel 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 Island from Puysegur around to Cape Reinga and extending south to Ahipara. Some land threat also exists for the Chatham Islands and Banks Peninsula i.e. wave heights between 1 and 3 metres. There may be some small observable sea level changes on parts of the west coast of both islands.

Wave heights refer to maximum water level relative 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 couldl occur between 6 and 12 hours after the initial arrivals.

People in coastal areas should:

1. Stay off beaches
2. Stay out of the water (sea, rivers and estuaries, including boating activities)
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 your local Civil Defence authorities.

MCDEM and scientific advisors are closely monitoring the situation to determine the severity of the threat to New Zealand.

This warning has been issued to all local civil defence authorities, emergency services, other agencies and media.

Summary:

Our threat assessment remains unchanged. Further science modelling has confirmed the original threat assessment. As at 0710 NZDT 28 February 2010 there are no measurements of tsunami waves on New Zealand coastal gauges (including the Chatham Islands). The situation continues to be monitored.

The Pacific Tsunami Warning Centre (PTWC) has issued a Tsunami Warning in response to the above earthquake.

Only messages issued by MCDEM represent the official warning status for New Zealand. Local civil defence authorities may supplement these messages by applying local threat assessments.

Confirmation has been received that a tsunami was generated. A wave measuring 2.34 metres was measured at Talcahuano, Chile and 0.35 metres at Easter Island, Chile.

The first wave to arrive to New Zealand will be in the areas around Chatham Islands (Waitangi) at approximately 07:05 NZDT, Sunday 28 February 2010. The first wave may arrive later and may not be the largest. Strong currents and unusual tidal effects may continue for several hours.
