A place where erosion of a [[cliffed coast]] has occurred is at [[Wamberal, New South Wales|Wamberal]] in the Central Coast region of New South Wales where houses built on top of the cliffs began to collapse into the sea. This is due to waves causing erosion of the primarily sedimentary material on which the buildings foundations sit.<ref>{{cite web|title=The Impact of Coastal Erosion in Australia|url=http://www.coastalwatch.com/environment/4524/impact-of-coastal-erosion-in-australia|url-status=live|archive-url=https://web.archive.org/web/20160315150115/http://www.coastalwatch.com/environment/4524/impact-of-coastal-erosion-in-australia|archive-date=15 March 2016|access-date=2016-03-15}}</ref>

[[Dunwich]], the capital of the [[England|English]] medieval [[wool]] trade, disappeared over the period of a few centuries due to redistribution of sediment by waves. Human interference can also increase coastal erosion: [[Hallsands]] in [[Devon]], England, was a coastal village washed away over the course of a year, 1917, directly due to earlier [[dredging]] of [[slate|shingle]] in the [[bay]] in front of it.

The California coast, which has soft cliffs of sedimentary rock and is heavily populated, regularly has incidents of house damage as cliffs erodes.<ref>{{Cite news|last=Xia|first=Rosanna|date=13 March 2019|title=Destruction from sea level rise in California could exceed worst wildfires and earthquakes, new research shows|newspaper=[[Los Angeles Times]]|url=https://www.latimes.com/local/lanow/la-me-california-coast-storm-damage-20190313-story.html|access-date=2019-03-15}}</ref> [[Devil's Slide (California)|Devil's Slide]], [[Santa Barbara, California|Santa Barbara]], the coast just north of [[Ensenada, Baja California|Ensenada]], and [[Malibu, California|Malibu]] are regularly affected.

The [[Coastal erosion in Yorkshire|Holderness]] coastline on the east coast of England, just north of the [[Humber Estuary]], is one of the fastest eroding coastlines in Europe due to its soft clay cliffs and powerful waves. [[Groynes]] and other artificial measures to keep it under control has only accelerated the process further down the coast, because [[longshore drift]] starves the beaches of sand, leaving them more exposed. The [[white cliffs of Dover]] have also been affected.

The coastline of [[North Cove, Washington]] has been eroding at a rate of over 100 feet per year, earning the area the nickname "Washaway Beach". Much of the original town has collapsed into the ocean. The area is said to be the fastest-eroding shore of the United States' West Coast. Measures were finally taken to slow the erosion, with substantial slowing of the process noted in 2018.<ref>{{cite news|last1=Banse|first1=Tom|title=New Hope To Stop Relentless Erosion of Washington's "Washaway Beach"|work=NW Public Broadcasting|url=https://www.nwpb.org/2018/05/23/new-hope-to-stop-or-greatly-slow-seemingly-unstoppable-shoreline-erosion/|access-date=16 October 2019}}</ref>

[[Fort Ricasoli]], a historic 17th century fortress in [[Malta]] is being threatened by coastal erosion, as it was built on a fault in the headland which is prone to erosion. A small part of one of the bastion walls has already collapsed since the land under it has eroded, and there are cracks in other walls as well.

In [[El Campello]], Spain, the erosion and failure of a Roman fish farm excavated from rock during the first century B.C. was exacerbated by the construction of a close sport harbour.<ref>{{Cite journal |first1=L. |last1=Aragonés |first2=R. |last2=Tomás |first3=M. |last3=Cano |first4=E. |last4=Rosillo |first5=I. |last5=López|date=2017|title=Influence of Maritime Construction within Protected Archaeological Sites along Coastal Areas: Los Baños De La Reina (Alicante), Spain|journal=Journal of Coastal Research|volume=33|issue=3|pages=642–652|doi=10.2112/JCOASTRES-D-16-00016.1|s2cid=132662199}}</ref>

[[Hampton-on-Sea]] is suffering from this problem as well. Hampton-on-Sea is located in Kent, England. It was at one time very popular for its oyster fishing and was very reliant on the sea. Hampton-on-Sea has undergone the effects of coastal erosion since before the 1800s. Hampton-on-Sea's coastal erosion worsened with the increase in global warming and climate change. Global warming is causing a rise in sea level, more intense and frequent storms, and an increase in ocean temperature and precipitation levels. Another reason Hampton-on-Sea had such a horrific case of coastal erosion is due to an increase in the frequency and the intensity of storms it experienced.<ref name="Coastal Erosion"/> These natural events had destroyed the Hampton Pier, Hernecliffe Gardens, a set of villas, several roads, and many other structures that once lay on Hampton-On-Sea. After this destruction, in 1899 they started building a sea wall to protect the rest of the remaining land and buildings. However, the sea wall did not offer much help: buildings continued to be affected by the erosion. Then a storm came and broke the sea wall, it then flooded the land behind it. These events cause many land investors to back out. Eventually, Hampton-on-Sea had to be abandoned because the erosion overtook so much of the land. By 1916 Hampton-on-Sea had been completely abandoned. By the 1920s only a couple of structures still stood. It was at that point that Hampton-on-Sea was said to have been finally drowned. Today only three landmarks have survived the tragedy that Hampton-on-Sea had faced. These landmarks include The Hampton Inn, The Hampton Pier, and a few roads. Although The Hampton Pier is not the same size as the original it is still available for people to fish from.

A study published in [[Earth's Future]], a journal by the [[American Geophysical Union]] in 2025 shows that coastal areas in arid regions, for example, in the [[Mediterranean]], are severely affected by erosion. In 2025, for example, more than 7,000 buildings in the harbor city of Alexandria are at risk of collapsing due to erosion processes and groundwater changes.<ref>{{cite journal |first1=Sara S. |last1=Fouad |first2=Essam |last2=Heggy |first3=Oula |last3=Amrouni |first4=Abderraouf |last4=Hzam |first5=Steffen |last5=Nijhuis |first6=Nesma |last6=Mohamed |first7=Ibrahim H. |last7=Saleh |first8=Seifeddine |last8=Jomaa |first9=Yasser |last9=Elsheshtawy |first10=Udo |last10=Weilacher |year=2025 |title=Soaring Building Collapses in Southern Mediterranean Coasts: Hydroclimatic Drivers & Adaptive Landscape Mitigations |journal=Earth's Future |volume=13 |issue=2 | doi=10.1029/2024EF004883|doi-access=free |bibcode=2025EaFut..1304883F }}</ref>

In South America, the Chilean coast has experienced erosion on certain beaches due to an increased frequency in severe storms during warm phases of the El Niño-Southern Oscillation phenomenon.<ref>{{Cite journal |last1=Vallarino Castillo |first1=Ruby |last2=Negro Valdecantos |first2=Vicente |last3=del Campo |first3=José María |date=2023-10-04 |title=Understanding the impact of hydrodynamics on coastal erosion in Latin America: a systematic review |journal=Frontiers in Environmental Science |language=English |volume=11 |doi=10.3389/fenvs.2023.1267402 |doi-access=free |bibcode=2023FrEnS..1167402V |issn=2296-665X}}</ref>
