The 20-year-old was returning home to the UK today from a diving competition in Shanghai when his Virgin Atlantic aircraft was diverted.
Tom tweeted: "Scary to emergency land in RUS after recent events, yet no word on what problem is after hour surrounded by fire engines #VirginAtlantic."
He also shared a picture to Instagram taken from the window of the plane, writing: "Just had to make an emergency landing in Irkutsk, Russia on the way back from Shanghai. Here's the pic of the fuel dump before landing."
Tom was travelling with his boyfriend, screenwriter Dustin Lance Black, who had been over in Shanghai supporting him at the latest Diving World Series event.
Lance, 40, shared a video of the fuel dump via Instagram.
"EMERGENCY LANDING into a Russian town," he told followers. This was our view over Mongolia. #VirginAtlantic #ScaryAsHell."
Lance then shared a collage of pictures including the scene on the ground and Tom staring out the window at the runway once they'd landed.
"Locked in the broken plane. No word on what's happening. #EmergencyLanding in Russia. #FireEngines abound. #NeedToPee!"
A spokesperson for Virgin Atlantic said: "Virgin Atlantic can confirm that the VS251 travelling from Shanghai to London Heathrow has diverted to Irkutsk Airport, Russia, as a precautionary measure due to a technical issue. Safety and security is always our top priority.
"The aircraft is currently on the ground and our customers are being looked after by our cabin crew. Our priority now is to ensure our customers resume their journey as soon as possible.
"The airline would like to thank passengers for their patience and apologise for any inconvenience caused."
