This book describes a search for geological evidence of meteorite impact structures in Britain.The statistics of impact structures indicate that Britain should have Phanerozoic impact structures up to tens of kilometres in diameter.A constant theme is the importance of atmospheric break-up of small asteroids and comets.These fragmenting bodies produce anomalously shallow craters with low rims and central peaks; three British structures of this type are identified.Analysis of fireball statistics implies that damaging fireball explosions occur over the British Isles on a time-scale of decades.On a time-scale of millennia, however, more damage is done by Atlantic impact tsunami.

Science, This book describes a search for geological evidence of meteorite impact structures in Britain. The statistics of impact structures indicate that Britain should have Phanerozoic impact structures up to tens of kilometres in diameter. A constant theme is the importance of atmospheric break-up of small asteroids and comets. These fragmenting bodies produce anomalously shallow craters with low rims and central peaks; three British structures of this type are identified. Analysis of fireball statistics implies that damaging fireball explosions occur over the British Isles on a time-scale of decades. On a time-scale of millennia, however, more damage is done by Atlantic impact tsunami.
