A £3m docu-drama about a devastating volcano due to be shown by the BBC at the end of January has been postponed in the wake of the tsunami disaster.
Supervolcano was due to air at the end of January
Supervolcano was based on events which could happen in the near future if the volcano underneath Yellowstone National Park in the US was to erupt.
The BBC said in light of the recent tragedies in Asia it would "be inappropriate" to screen it.
The documentary will be screened at a later date, the spokesman added.
Based on fact, Supervolcano merges science, drama and computer imagery to imagine the effects of a volcano eruption.
The expensive series is a co-production between the BBC and other worldwide partners including the Discovery Channel.
There is a real active supervolcano underneath Yellowstone National Park that last erupted 640,000 years ago.
Predicting the future
Scientists believe that its cyclical nature means an eruption is long overdue and has the potential to kill 100,000 US citizens and lead to blizzards, climate change and famine.
The docu-drama was to be accompanied by a documentary, The Science Behind the Supervolcano, which looks at the scientific evidence and behaviour of the phenomenon.
The docu-drama follows a BBC Two series, If..., which examined what could happen in the event of man-made disasters, including a fictionalised plane crash which brings the UK to a standstill.
Another in the series, If...The Lights Go Out, predicted what would happen in the event of a nationwide powercut.
