Quake and Tsunami alert!!

Tsunami warning issued in New Zealand after Pacific quake

 Jul 6, 2011 

WASHINGTON — A powerful magnitude 7.8 earthquake struck off New Zealand’s Kermadec Islands, triggering a tsunami in the region, the U.S. Geological Survey and the U.S. Pacific Tsunami Center said on Wednesday.
The quake, initially reported as a magnitude 7.9, triggered a tsunami warning for New Zealand, the Kermadec Islands and Tonga, the U.S. Pacific Tsunami Center said.
“Sea level readings confirm that a tsunami was generated. This tsunami may have been destructive along coastlines of the region near the earthquake epicenter,” the U.S. Pacific Tsunami Center said in its warning.
It struck at 7:03 a.m. on Thursday at the epicenter, 211 kilometres east of Raoul Island, part of the Kermadec archipelago, and was only 48 kilometres deep, the USGS said.
The Pacific Tsunami Center said waves were 68-84 cm high around Raoul Island.
The U.S. Pacific Tsunami Center said it estimated that waves would reach East Cape in New Zealand within two hours and Auckland within three hours of the quake.
The Kermadec Islands, which are New Zealand’s northernmost inhabited islands, are 800 kilometres northeast of New Zealand’s North Island.

Magnitude 7.9 Earthquake off Kermadec Islands, Tsunami Warning Issued for New Zealand

The United States Geological Survey says the quake was centred 211km east of Raoul Island in the Kermadecs, at a depth of 48km.
The US Pacific Tsunami Center has issued a tsunami warning for New Zealand, the Kermadec Islands and Tonga.
However, the centre says it does not yet know whether an actual tsunami has developed.
NZ awaits tsunami after 7.6 quake
A tsunami warning has been issued for New Zealand following a 7.6 magnitude earthquake off the Kermadec Islands this morning.
The Pacific Tsunami Warning Centre has issued a warning for New Zealand, Tonga and the Kermadec Islands.
The United States Geological Survey reports the quake struck at 7.03am at a depth of 20km, and was centred 211km east of Raoul Island.
John Bellini, a seismologist with the U.S. Geological Survey’s National Earthquake Information Centre, said it was uncertain if a tsunami was on the way to New Zealand.
It would strike the East Cape around 9.00 am and Auckland around 10.00am.
The Kermadec Islands are a island chain 800km north of New Zealand.
Tsunami may be over 1 metre
