Powerful and shallow 7.6 quake hits New Caledonia – NO TSUNAMI THREAT FOR NZ

UPDATED 5:51pm — A magnitude 7.6 quake, just 10kms deep (according to the USGS) has hit near Noumea, New Caledonia north of New Zealand.

New Zealand Civil Defence has just issued a statement saying there is NO TSUNAMI THREAT TO NEW ZEALAND.

A short time before said the region wasn’t known for generating serious tsunami for New Zealand but everyone should keep up to date with more information as it comes in this evening.

Despite the “no tsunami threat” New Zealanders should remain aware of conditions as Civil Defence advice in this area hasn’t always been top notch, but supports the latest Civil Defence update below:

National Advisory: No Tsunami Threat to New Zealand

National Warning System Message No: 2

Issued 17:47 05 December 2018

More Detail: An earthquake has occurred with these parameters: 

Origin time:

2018-12-05 17:18

NZ time:

22.1 SOUTH 169.2 EAST

The above magnitude is provisional and may be increased or decreased as more seismic data becomes available.
This message is current and replaces all/any previous messages for this event.

MCDEM has assessed the information with the assistance of science advisors. Based on current information, the initial assessment is that the earthquake is unlikely to have caused a tsunami that will affect New Zealand.

This advisory has been issued to all local Civil Defence authorities, emergency services, other agencies and media.
This will be the final message via the National Warning System for this event unless the event parameters change significantly.

Only messages issued by the Ministry of Civil Defence & Emergency Management represent the official warning status for New Zealand.

Looks like the nearest wave height buoys all went into “Event Mode”. Roughly 10cm drop on each. I’m no expert on how to interpret that however.
