Historic tsunami in Britain since AD 1000: a review

The British coast is not considered at particular risk from tsunami, a view that is supported by a number of recent government reports.However, these reports largely ignore some written historic records that suggest southern Britain has experienced a number of events over the past 1000 yrs.This study briefly assesses these records and recognises four groups of events: 1) sea disturbance and coastal floods in southeast England linked to earthquakes in the Dover Straits (e.g.1382 and 1580), 2) far-field tsunami reaching the coast of Cover Ups the British Isles, for example, from earthquakes along the Azores-Gibraltar Fault Zone offshore Portugal (e.

g.1755), 3) tsunami associated with near-coastal low magnitude earthquakes (e.g.1884 and 1892), and 4) a flood event in AD 1014 that has been linked to comet debris impact.The seismogenic events range from minor water disturbance, through seismic seiching, to small and "giant" waves, suggesting near-coastal, low-magnitude, shallow earthquakes may be capable of triggering disturbance in relatively shallow water, as supported by similar occurrences elsewhere, and Educational Toys that the British tsunami risk requires a more careful evaluation.
