The number of outputs using the keyword "landslide" in the period 1994 to 2025 inclusive, via Scopus.
Since 1994 there has been a 32 times increase in the number of research outputs with the keyword "landslide". This represents a diversification of the discipline areas with an interest in landslides, and in the geography of the researchers themselves.

The relationship between the land-cover change rate and the density of fatal landslides for mountain areas around the world. Figure from Fidan et al. (2026), published under a Creative Commons Licence.
A new paper Fidan et al. (2026) demonstrates that wealth and the rate of land-cover change play a key role in determining the occurrence of fatal landslides in mountain areas. These factors are statistically more significant that precipitation and topography.

The cumulative total number of fatal landslides through to March 2026, plotted with the long term mean number and the exceptional year of 2024 for comparison.
In March 2026 I recorded 61 fatal landslides causing 520 fatalities, the highest March total on record.

As an aside, there's an interesting difference between the UK and the USA in thart image. In the UK, the management of risk would never allow us to be under those cliffs without a helmet. Apparently not so in the US?
Lots of these unpaved new roads cutting across slopes in Canadian mountains, mostly associated with forestry and mining.
A new paper (Adhikari et al. 2026) in the journal Asian Development Review shows that earthen roads in the hilly areas of Nepal generate limited economic benefits but carry a high landslide cost. This challenges a fundamental development principle in mountain areas.

This must be the site of the deadly Rubaya landslide from early March. This area is v. cloudy and so decent satellite imagery (as in this example from @planet.com) are rare. The slide looks to have buried some buildings (no more than half dozen) in the main slide path w/ maybe more on the plateau π§ͺβοΈ

The number of fatal landslides each year since 1968 in Nepal. The grey line is a four year retrospective running mean. Author's own dataset.
Since 1968 there have been over 1,400 fatal landslides in Nepal, killing over 6,000 people. The data shows that the impacts are increasing with time.
