Storm Event

‘the most destructive weather-related disaster ever to hit the British Isles’

Severity ? 6


The storm developed over the Atlantic Ocean and moved across Western Europe creating a south-westerly gale (English Towns, 2014). As the depression approached the North Sea, it combined with high tides and produce a storm surge. The storm surge impacted eastern part of England like a tsunami (Nobbs, 2015).

Receptor and Consequence

s event was known as Saint Marcellus’ flood or Grote Mandreke (which means the ‘Great Drowning of Men’). This event was deemed as ‘the most destructive weather-related disaster ever to hit the British Isles’ (Moss, 2014). It was reported that at least 25,000 people in south-east England and the nearby Netherlands were killed, either as the result of high winds  as trees, homes, and churches collapsed or drowned as a result of the storm surge (Moss, 2014; Liddell, 2016). The flood demolished a major fishing port in Holderness, Yorkshire called Ravenser Odd (Nobbs, 2015). The port of Dunwich in East Anglia were also severely damaged causing the decline of the port soon after. 400 houses were also damaged along the coastlines of Dunwich (Liddell, 2016).
