The disappearance of missing Malaysia Airlines Flight 370 is still aviation's biggest mystery, with very few clues found leading the search team for seven months now.

BBC reported that new images reveal details of the seabed featuring extinct volcanoes and 1,400 meters of depressions.

Australian Transport Safety Bureau (ATSB) leads the search for Malaysia Airlines Flight 370.

They are using sonar maps to guide them around this new priority search area at the bottom of the Southern Indian Ocean.

The team deploys around two or three deep-sea vehicles to thoroughly go through the ocean floor and launch "inch-by-inch seabed search for wreckage" to be found.

While it is presumed that the aircraft carrying 239 passengers and crewmembers crashed into the vast ocean near Australia, the global drive to find the missing Flight MH370 has not ceased.

In fact, United Nation's aviation body is expecting recommendations on improved plane tracking strategies from IATA on December.

"After an exhaustive internal review, it was determined that we needed more clarification on the recommendations and on guidance for implementation," IATA spokeswoman Mona Aubin said in an email.

"I would like to ensure that expectations are appropriate as to what will be produced. This will not be a final document or a silver bullet solution," IATA Director General Tony Tyler said, according to remarks posted on IATA's website.

Malaysia Airlines Flight 370 bound for Beijing departed Kuala Lumpur on March 8, but no trace of the Boeing 777 has ever been seen or found since.

It has been ultra challenging for the task force to find the missing plane, but this does not compare to the emotional, physical and financial trauma that this tragic incident has brought to relatives of the missing passengers.
