The search area for missing Malaysian flight MH370 will shift further south in the Indian Ocean to a 60,000-square-kilometre arc after analysis of satellite data, Australia's Deputy Prime Minister Warren Truss announced Thursday.
"The new priority area is still focused on the seventh arc where the aircraft last communicated with satellites," Truss said.
"We are now shifting our attention to an area further south along the arc based on these calculations."
The Boeing 777 with 239 passengers and crew disappeared on March 8shortly after leaving Kuala Lumpur bound for Beijing.
Mapping of the 6-kilometre-deep ocean floor will take another three months and a search of the sea floor is expected to begin in August and take up to 12 months.
Much of the area is covered by a flat plateau but if the plane sank into one of the deep trenches it could be very difficult to find.
