* [[Storegga Slide]], some 8,000 years ago off the western coast of [[Norway]]. Caused massive [[tsunamis]] in [[Doggerland]] and other areas connected to the [[North Sea]]. A total volume of {{convert|3,500|km3|abbr=on}} debris was involved; comparable to a {{convert|34|m|ft|abbr=on}} thick area the size of Iceland. The submarine landslide is thought to be among the largest in history.<ref>{{Cite journal |last=Bugge |first=Tom |last2=Befring |first2=Stein |last3=Belderson |first3=Robert H. |last4=Eidvin |first4=Tor |last5=Jansen |first5=Eystein |last6=Kenyon |first6=Neil H. |last7=Holtedahl |first7=Hans |last8=Sejrup |first8=Hans Petter |date=December 1987 |title=A giant three-stage submarine slide off Norway |url=http://link.springer.com/10.1007/BF02242771 |journal=Geo-Marine Letters |language=en |volume=7 |issue=4 |pages=191–198 |doi=10.1007/BF02242771 |issn=0276-0460}}</ref>
* Landslide which moved [[Heart Mountain (Wyoming)|Heart Mountain]] to its current location, the largest continental landslide discovered so far. In the 48&nbsp;million years since the slide occurred, erosion has removed most of the portion of the slide.
* [[Flims Rockslide]], about {{convert|12|km3|mi3|abbr=on}}, Switzerland, some 10,000 years ago in post-glacial [[Pleistocene]]/[[Holocene]], the largest so far described in the Alps and on dry land that can be easily identified in a modestly eroded state.<ref>[http://www.angewandte-geologie.ch/Archiv/Volumes/vol112.htm Weitere Erkenntnisse und weitere Fragen zum Flimser Bergsturz] {{webarchive|url=https://web.archive.org/web/20110706221400/http://www.angewandte-geologie.ch/Archiv/Volumes/vol112.htm |date=2011-07-06 }} A.v.

* The landslide around 200&nbsp;BC which formed [[Lake Waikaremoana]] on the [[North Island]] of New Zealand, where a large block of the Ngamoko Range slid and dammed a gorge of Waikaretaheke River, forming a natural reservoir up to {{convert|256|m}} deep.
* [[Cheekye Fan]], [[British Columbia]], Canada, about {{convert|25|km2|mi2|abbr=on}}, [[Late Pleistocene]] in age.
* The Manang-Braga rock avalanche/debris flow may have formed Marsyangdi Valley in the Annapurna Region, [[Nepal]], during an interstadial period belonging to the last glacial period.<ref>{{Cite journal|title=Two large late quaternary rock slope failures and their geomorphic significance, Annapurna, Himalayas (Nepal)|journal=Geografia Fisica e Dinamica Quaternaria|volume=34 |year=2011|pages=5–16|author=Fort, Monique|url=https://www.researchgate.net/publication/235964481}}</ref> Over {{cvt|15|km3}} of material are estimated to have been moved in the single event, making it one of the largest continental landslides.{{Citation needed|date=October 2022}}
