A powerful dust devil tornado terrified workers in the Philippines.

The violent whirlwind tore through a garage while workers were having their lunch break in Zamboanga City on February 1.

It reached up to 15ft-high before the wind phenomenon rotated towards the parked vehicles as shocked workers watched from a distance.

Onlooker Ged Marmoleno said: 'I was taking a lunch break outside our workplace when a strong twister formed in front of me.

'I was surprised at first but I tried to stay calm to witness the extraordinary scene. Some of my colleagues saw it too.'

After about five minutes, the whirlwind dissolved by itself without leaving any damage. No one was also hurt from the incident.

Dust devils are a type of whirlwind tornado that form when the sun heats a patch of land and the air above becomes warmer and rises quickly.

Cooler air then moves into the low-pressure gap left by the rising warm air. The new drafts of cooler air also heat up, rise and the cycle continues, picking up dust and debris making the spiral visible.
