A multinational fleet of planes and ships raced Friday to a fresh search zone after a "credible new lead" that Malaysia Airlines Flight MH370 was flying faster than first thought before it plunged into the remote Indian Ocean.
Ten aircraft from six countries -- Australia, China, Japan, New Zealand, South Korea and the United States -- diverted to an area 1,100 kilometers (685 miles) northeast of where they have been looking for a week, far off western Australia.

Five Chinese ships and an Australian naval vessel were also steaming to the new zone of interest after the weather cleared following the suspension of the air search Thursday due to thunderstorms and high winds, the Australian Maritime Safety Authority said.

"The new information is based on continuing analysis of radar data between the South China Sea and the Strait of Malacca before radar contact was lost (with the missing plane)," AMSA said.

"It indicated that the aircraft was travelling faster than previously estimated, resulting in increased fuel usage and reducing the possible distance the aircraft travelled south into the Indian Ocean."

The new area is closer to land, meaning planes can spend more time searching before having to return to refuel, and the weather is expected to be better there.

The new search area "has moved out of the Roaring Forties (strong westerly winds), which creates very adverse weather frequently", AMSA chief John Young told reporters in Canberra.

Satellite sightings of unidentified debris in recent days have raised hopes of finding wreckage from the Boeing 777, which vanished on March 8 with 239 people on board after veering sharply off course during a flight from Kuala Lumpur to Beijing and flying thousands of miles southwards.

Malaysia believes the plane was deliberately redirected by someone on board, but nothing else is known.

Thailand Thursday reported a sighting of 300 floating objects. Japan also announced a satellite analysis indicated around 10 square floating objects, although it was not clear if these were in the zones the new search would focus on.

Japan's Cabinet Satellite Intelligence Centre's study showed the objects it sighted on Wednesday were up to eight meters in length and four meters wide. Jiji Press cited an official at the office as saying they were "highly likely" to be from the plane.

The Thai and Japanese sightings came after satellite data from Australia, China and France had also shown floating objects possibly related to flight MH370. But nothing has so far been retrieved despite the huge multinational search.

"This is a credible new lead and will be thoroughly investigated today," Australian Prime Minister Tony Abbott said of the revised search area.

The updated advice was provided by an international investigation team in Malaysia, with the Australian Transport Safety Bureau determining "that this is the most credible lead to where debris may be located".

The new search area measures about 319,000 square kilometers (127,600 sq miles) and is around 1,850 kilometers west of Perth. Australia is re-positioning its satellites to focus on it.
