What the record says
NCEI’s account, from the sources it cites.
Cornwall and Scilly Isles 1859. On the 25 June 1859, there was an exceptional episode of coastal flooding along the coast of Cornwall as described by Dawson et al. (2000) referencing Edmonds’ (1856) report in the Edinburgh New Philosophical Journal. Edmonds (1862) reports considerable oscillations, together with thunderstorms with violent squalls, which suggests that it was most likely a meteotsunami. (reference #14269)
