This post presents the data from the Durham University Fatal Landslide database for 2009. First, this is the map of fatal landslides. Each red dot represents a single landslide recorded on the database. Click on the map for a better view in a new window:
The map shows the usual distribution. Note the high incidence of landslides in SW India, the Philippines and in java in Indonesia. The high occurrence of landslides along the southern margin of the Himalayan mountain chain is also clear, but is less continuous than usual. This reflects the 2009 monsoon rainfall pattern, which was substantially below average, especially in the northwest of India, as the map below (for India only), from Monsoon Online, shows. The map indicates the departure from the mean annual monsoon rainfall:
- Number of recorded fatal landslides: 493 (this is substantially above the long term average).
- Number of recorded fatalities: 3611 (this is substantially below the long term average, primarily because there were no large earthquakes in populated mountainous areas).
