| Zusammenfassung |
| A new data set of landslides that caused loss of life in Latin America and the
Caribbean in the 10-year period from 2004 and 2013 inclusive has been
compiled, providing new insight into the impact of landslides in this key
part of the world. This data set indicates that in the 10-year period a total
of 11 631 people lost their lives across the region in 611 landslides. The
geographical distribution of the landslides is highly heterogeneous, with
areas of high incidence in parts of the Caribbean (most notably Haiti),
Central America, Colombia, and southeast Brazil. There is significant interannual
variation in the number of landslides, with the El Niño/La Niña cycle
emerging as a key control. Our analysis suggests that on a continental scale
the mapped factors that best explain the observed distribution are
topography, annual precipitation and population density. On a national basis
we have compared the occurrence of fatality-inducing landslide occurrence
with the production of locally authored research articles, demonstrating that
there is a landslide research deficit in Latin America and the Caribbean.
Understanding better the mechanisms, distribution causes and triggers of
landslides in Latin America and the Caribbean must be an essential first step
towards managing the hazard. |
