The Happisburgh coast in Norfolk, England, is known for its rapid erosion. However, it's important to note that erosion rates are not consistent and can vary significantly depending on factors like weather conditions, sea levels, and storm events.

Current estimates suggest that Happisburgh erodes at a rate of approximately 1 to 2 meters per year. However, this is just an average. Some years see significantly more erosion than others.

For example, in 2013, a single storm eroded up to 10 meters of coastline in a matter of hours.

It's crucial to understand that these are estimates, and the actual erosion rate can be much higher or lower in any given year.
