\nFrom the BBC<\/a>:<\/p>\n

A tsunami warning has been issued for 11 nations in the south-west Pacific, including Papua New Guinea, after a 7.8-magnitude earthquake off Vanuatu.<\/p>\n

The epicentre was 295km (180 miles) north-northwest of Vanuatu’s largest island, Santo, at a depth of 35km (21.7 miles), the US Geological Survey said. <\/p><\/blockquote>\n

Here is the USGS data for the earthquake<\/a>:<\/p>\n

THIS BULLETIN IS ISSUED AS ADVICE TO GOVERNMENT AGENCIES. ONLY NATIONAL AND LOCAL GOVERNMENT AGENCIES HAVE THE AUTHORITY TO MAKE DECISIONS REGARDING THE OFFICIAL STATE OF ALERT IN THEIR AREA AND ANY ACTIONS TO BE TAKEN IN RESPONSE.<\/p>\n

AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS<\/p>\n

ORIGIN TIME – 2203Z 07 OCT 2009 COORDINATES – 13.0 SOUTH 166.3 EAST DEPTH – 33 KM LOCATION – VANUATU ISLANDS MAGNITUDE – 8.0<\/p>\n

EVALUATION<\/p>\n

IT IS NOT KNOWN THAT A TSUNAMI WAS GENERATED. THIS WARNING IS BASED ONLY ON THE EARTHQUAKE EVALUATION. AN EARTHQUAKE OF THIS SIZE HAS THE POTENTIAL TO GENERATE A DESTRUCTIVE TSUNAMI THAT CAN STRIKE COASTLINES NEAR THE EPICENTER WITHIN MINUTES AND MORE DISTANT COASTLINES WITHIN HOURS. AUTHORITIES SHOULD TAKE APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS CENTER WILL MONITOR SEA LEVEL DATA FROM GAUGES NEAR THE EARTHQUAKE TO DETERMINE IF A TSUNAMI WAS GENERATED AND ESTIMATE THE SEVERITY OF THE THREAT.<\/p>\n

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.<\/p>\n

The web site for the NOAA tsunami warning center<\/a> is not operating or is under such heavy use as to be useless. Obviously, there is a need for an upgrade in that technology.<\/p>\n
