Criteria for inclusion?
Other than has reliable sources, what are the criteria for including any particular landslide (or group of landslides) on this list? Obviously, any landslide which is in the range of tens of millions of cubic meters, or one which kills thousands of people, is probably worth including, but where are the limits? What would make a smaller or less deadly landslide worth including?
The 21st century part of the list is already nearly as big as the 20th century, and that will remain true even once I'm done transferring landslides from list of historic landslides, primarily because of better (and more net-accessible) news coverage. Having some sort of criteria will keep the 21st century section from overwhelming the 20th century section.
Also, geologically speaking, what qualifies? Classic rotational and translational slides, and debris flows should count, obviously. Do rockfalls count? Do avalanches count? Do groups of landslides which collectively do a lot of damage count, or only single large incidents?

- In my personal (unprofessional but educated) opinion, landslides can be of any sufficient size. Rockslides also count. Rockfalls probably don't, as it's just some rocks falling without a fundamental slip of the terrain. Avalanches are related, but they're made of snow which is transient by its nature. (However, on moons in the outer Solar System, permanent non-flowing ice that is considered part of the fundamental terrain could be considered a landslide if the terrain slips.) Pyroclastic flows, like avalanches, are made of transient material that require great heating of hot gases and material. However, the natural landslide that triggered the 1980 eruption of Mount Saint Helens would qualify, as it unplugged the vent rather than being erupted from it—the landslide itself was also largely cooled rock that was being pushed by newer hotter rock from underneath. I'm uncertain whether to say all mudslides (including lahars) are landslides, though some of them probably are, since they already have many features in common (both landslides and mudslides can be triggered by oversaturation of water in the ground). - Gilgamesh (talk) 19:41, 25 November 2010 (UTC)
- Lots of good questions there. For earthquakes I came up with a set of criteria for notability but there you have parameters such as magnitude and intensity, and several reliable global or local catalogues to check them out. For landslides it's more difficult, although I agree that more than one death, mentions in the media (other than just at the time) and coverage in scientific papers would all establish notability. That will still leave quite a lot of landslides to deal with. For the older ones, it you can find them in reliable sources, then that's almost definitely OK. For ones that are very recent, we don't have the benefit of hindsight to help us decide on the notability. This list will I think naturally evolve into separate lists referring to pre-historic, pre-20th century, 20th century and 21st century (which might eventually be split into individual decades - I'm fairly sure that will happen to the list of 21st-century earthquakes).
- As to types of 'landslides' in the broad sense, I think that avalanches should be separate unless they involved rock as they move downslope, pyroclastic flows definitely not I think, but lahars just as clearly yes (once formed they develop just like mudslides), earthflows, flowslides, mudslides, debris flows, rockslides all OK. Rockfalls, there I think that if a single block falls on somebody, probably not but some rockfalls have a perceptible runout, so may qualify. As to individual events versus groups of events, they're both OK, groups of landslides are generally triggered by the same event, earthquake or tropical storm rainfall, so can be considered together.

- There's a paper by the USGS Significant Landslide Events in the United States, which lists quite a few landslides in the U.S. There are probably similar catalogs for most countries which have agencies equivalent to the USGS, and the USGS may have some of those catalogs in translation.
