In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet. When the fragments landed in the southern hemisphere of the giant planet, the explosions were watched by astronomers on the Earth. But what if our own planet was hit by a comet? 030

The year is 2094. It has been announced that a comet is heading towards the Earth. Most of will miss our planet, but two fragments will probably hit the southern hemisphere. The news has caused panic. Stock markets around the world have been thrown into chaos.
On 17 July, afragment four kilometres wide enters the Earth's atmosphere with a massive explosion. About half of the fragment is destroyed and pieces are scattered through the atmosphere. But the core survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. An enormous tidal wave is created and spreads outwards from the hole.The wall of water, a kilometre high, rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia. Coastal cities are evacuated and thousands are killed in the panic. Before the wave reaches South America, the second fragment of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes.
