This is the dramatic moment terrified passengers screamed as they flew through turbulence caused by Super Typhoon Ragasa.

Footage shows the travellers yelping in fear as the storm rattled the plane cabin on September 22.

Children burst into tears while flight attendants were forced to crouch down on the aisle to steady themselves on Taiwanese airline EVA Air flight BR115 from Japan to Taipei, Taiwan.

A passenger named Yaqi said: 'We just flew back from Hokkaido and encountered turbulence. I was scared to death. I was bouncing up and down in my seat.'

Super Typhoon Ragasa, said to be the strongest storm of the year so far, is roaring towards Hong Kong after tearing through the northern tip of the Philippines, killing at least one and displacing thousands.

It made landfall in the country's remote and poverty-stricken Babuyan Islands at 3 pm local time on Monday. It arrived as the Philippines continues to grapple with weeks of severe flooding brought on by an unusually intense monsoon season.

Hong Kong authorities have grounded at least 700 flights from Tuesday evening as Ragasa barrels toward the Chinese coast. Locals have also cleared grocery shelves as they prepared to hunker down in their homes.
