This Darjeeling landslide disaster appears to have been triggered by a strong rainfall event on 12th June 1950, in which 546 mm of rainfall fell.  As a result, 127 people are known to have died in the landslides.

Included in the presentation are some quite wonderful photographs of the landslides, taken by Durga Das Pradhan, the majority of which appear to have been shallow failures such as this:

However, there is one case of a shallow slide that appears to have become a channelised debris flow:

And one landslide that has a rather complex morphology (take a look at the railway line):
