Abstract/Summary

This paper examined the occurrence and seasonality of meteotsunami in the United Kingdom (UK) to present a revised and updated catalogue of events occurring since 1750. Previous case studies have alluded to a summer prevalence and rarity of this hazard in the UK. We have verified and classified 98 events using a developed set of identification criteria. The results have revealed a prominent seasonal pattern of winter events which are related to mid latitude depressions with precipitating convective weather systems. A geographical pattern has also emerged, highlighting three ‘hotspot’ areas at the highest risk from meteotsunami. The evidence reviewed, and new data presented here shows that the hazard posed by meteotsunami has been underestimated in the UK.
