Infonews editor Fraser Mills described the earthquake, as felt from Wanaka, as a "long rolling quake" which "shook doors, rattled cupboards" and the house he was in.

Fiordland quake “a good shake” - Civil Defence Emergency Management Group
Tonight’s Fiordland earthquake gave the Southland region “a good shake” but was not particularly damaging, according to Southland Civil Defence Emergency Management Controller Neil Cruickshank. Mr Cruickshank said that the region’s Emergency Operations Centre had monitored the situation throughout the evening and would continue follow up work in the morning. “Invercargill reports that phone services were down in east Invercargill and power was out for some time in the suburb of Otatara because of the earthquake. “Southland District Council reports that in the Milford and Te Anau areas there were no reports of substantial damage and the infrastructure in those areas appears to be working well. Inquiries are continuing to assess damage around the Tuatapere area.” Mr Cruickshank said there had been conflicting reports of the size, depth and location of the earthquake from the various monitoring agencies. A tsunami warning had been issued and Southland Civil Defence Emergency Management had monitored sea levels through people and equipment stationed at Bluff. A .17m tsunami had been detected at Jackson Bay on the West Coast and the tsunami warning had subsequently been cancelled, he said. Mr Cruickshank said that in the morning Environment Southland staff, in co-operation with other agencies, would begin air reconnaissance in the morning to check for landslides in Fiordland. The region’s substantial roading network, particularly state highways and bridges, and remote DOC huts would also be checked as a precaution. No further media releases will be issued tonight.

U.S. West Coast, Alaska, and British Columbia coastal regions
From: NOAA/NWS/West Coast and Alaska Tsunami Warning Center
Subject: Tsunami Information Statement #1 issued 07/15/2009 at 2:44AM PDT

A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas.

Based on the earthquake magnitude, location and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts. At coastal locations which have experienced strong ground shaking, local tsunamis are possible due to underwater landslides.

At 2:23 AM Pacific Daylight Time on July 15, an earthquake with preliminary magnitude 7.8 occurred off the west coast of South Island, New Zealand. (Refer to the United States Geological Survey for official earthquake parameters.)

The Pacific Tsunami Warning Center in Ewa Beach, Hawaii will issue a tsunami warning for regions near the epicenter.

This will be the only statement issued for this event by the West Coast/Alaska Tsunami Warning Center unless conditions warrant. See the WCATWC web site for basic tsunami information, safety rules, and a tsunami travel time map and table. (NOTE: Travel time maps and tables indicate forecasted times only, not that a wave was generated.)

Potential tsunami threat to New Zealand

It is possible that there is a tsunami risk to New Zealand from the 7.8 earthquake that occurred near Tuatapere today at 2123 NZST. The Ministry of Civil Defence & Emergency Management is continuing to monitor the situation.

This message is not a warning but an advisory for the public to continue listening for further information. The Ministry will, as soon as possible, follow this media release with either a cancellation or an official warning.

The Ministry’s Director, John Hamilton, said that the Ministry has received information about the earthquake from the Pacific Tsunami Warning Centre (PTWC) in Hawaii and GNS Science in New Zealand.

The information from PTWC and GNS Science indicates there is a possibility of tsunami risk to New Zealand.

“GNS Science is closely monitoring and analysing all available New Zealand and international data about the earthquake as well as the sea levels, and may convene the tsunami expert panel,” Mr Hamilton said.
“The Ministry will release further information as soon as it becomes available”.

TSUNAMI WARNING NUMBER 2 FOR LORD HOWE ISLAND
Issued by the Joint Australian Tsunami Warning Centre (JATWC) at
09:07 PM EST on Wednesday 15 July 2009

********************************************************************************

TSUNAMI THREAT TO LOW-LYING COASTAL AREAS AND THE MARINE ENVIRONMENT

********************************************************************************
SUMMARY:

Tsunami warning for LORD HOWE ISLAND.

An undersea earthquake of magnitude 7.9 (Latitude 45.960S Longitude 166.470E )
has occurred at 07:22 PM EST on Wednesday 15 July 2009 near OFF W. COAST OF
S. ISLAND, N.Z..

For low-lying coastal areas there is a threat of MAJOR LAND INUNDATION,
FLOODING, DANGEROUS WAVES AND STRONG OCEAN CURRENTS for several hours from
09:30 pm (EST) Wednesday.

People in affected areas are strongly advised by the NSW STATE EMERGENCY SERVICE
to go to higher ground or at least one kilometre inland.

For all threatened areas, people are advised to get out of the water and move
away from the immediate water’s edge.

Next update will be issued by 10:07 PM EST on Wednesday 15 July 2009

For latest and further information call 1300 TSUNAMI (1300 878 6264) or visit

********************************************************************************
DETAILS:

TSUNAMI THREAT TO LOW-LYING COASTAL AREAS
A threat of MAJOR LAND INUNDATION, FLOODING, DANGEROUS WAVES AND STRONG OCEAN
CURRENTS exists for several hours from 09:30 pm (EST) Wednesday.

COMMUNITY RESPONSE ADVICE FROM THE NSW STATE EMERGENCY SERVICE:

- The NSW STATE EMERGENCY SERVICE has ordered the evacuation of low-lying parts
of coastal towns and villages.

- People are strongly advised to go to higher ground, at least ten metres
above sea level, or if possible move at least one kilometre away from all
beaches and the water's edge of harbours and coastal estuaries.

- Take only essential items that you can carry including important papers,
family photographs and medical needs.

- It may be in your own interests to walk to safety if possible to avoid
traffic jams.

- If you cannot leave the area take shelter in the upper storey of a sturdy
brick or concrete multi-storey building.

- Boats in harbours, estuaries or shallow coastal water should return to
shore. Secure your boat and move away from the waterfront.

- Vessels already at sea should stay offshore in deep water until further
advised.

- Do not go to the coast to watch the tsunami, as there is the possibility of
dangerous, localised land inundation of the immediate foreshore.

- Check that your neighbours have received this advice.

CAUTION:
Tsunami waves are more powerful than the same size beach waves, with the first
wave not necessarily being the largest.

Low-level effects may be observed in neighbouring coastal areas. People are
advised to take care.

CANCELLATION OF TSUNAMI WARNING FOR LORD HOWE ISLAND
Issued by the Joint Australian Tsunami Warning Centre (JATWC) at
01:03 AM EST on Thursday 16 July 2009

********************************************************************************
SUMMARY:

A tsunami was generated by an undersea earthquake of magnitude 7.9 (Latitude

July 2009 near OFF W. COAST OF S. ISLAND, N.Z.

The main tsunami waves have now passed all expected Australian locations.

Small unusual waves may continue but are NOT now expected to be damaging.

Tsunami warnings for LORD HOWE ISLAND are therefore CANCELLED.

No updates or further warnings will be issued unless the situation changes.

Your local emergency management authority will advise the All Clear when it's
safe to return to coastal areas.

The NSW State Emergency Service advises people near the coast or coastal
waterways to be aware that although the main tsunami threat has passed, small
unusual waves and currents and abnormal tides may still affect some beaches,
harbours and coastal waterways for many hours or even days.
