Just reported on FOX
A BIG shake...............
Wow. Big one.
7.8 on USGS, out in the ocean quite a bit.
30°S,175°W
all of NZ is on a fault
About 800 miles from Auckland and 650 miles from Tonga.
Wowee!
Bush's Fault?
Any Tsunami warnings yet?
I think it happened a wee bit before Bush’s time
:)
ping- I think a tsunami warning has been issued.
BTTT
The quake appears to be near the Kermadec Trench, where the Pacific Plate is being subducted beneath the Indo-Australian plate.
Mid-way between the northern edge of NZ and American Samoa. Out in the middle of nowhere, really.
Tsunami watch is the important thing.

To: 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 07/6/2011 at 12:13PM 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 12:03 PM Pacific Daylight Time on July 6, an earthquake with preliminary magnitude 7.8 occurred in the Kermadec Islands region, north of New Zealand . (Refer to the United States Geological Survey for official earthquake parameters.)
Pacific coastal regions outside California, Oregon, Washington, British Columbia, and Alaska should refer to the Pacific Tsunami Warning Center messages for information on the event.
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.)
Ping
USGS is now showing the depth at 1 km, which seems a bit unrealistic, although it does say the depth is “poorly constrained” at this point.
