Dr Sergio Sepulveda from the University of Chile is visiting Durham University as a Cofund Senior Research Fellow through the Institute of Advanced Study, to work with the International Landslide Centre at IHRR that is led by Professor Dave Petley and Dr Nick Rosser from the Department of Geography. Sepulveda is from Chile, one of the most seismically active parts of the world that regularly experiences earthquakes, landslides, debris flows, volcanic eruptions and other geohazards.
Sepulveda is a leading researcher on landslides in South America and is well-known in the field. Most of the fatalities caused by natural hazards in South America are from earthquakes, floods and landslides that affect both urban and rural communities. Sepulveda is working closely with colleagues in IHRR to identify the vulnerability of populations in Latin America and the Caribbean to landslides, in order to acquire a better understanding that would lead to developing measures to help reduce fatalities, and is testing a number of volcanic soils from Chile to understand the role they play in landslides and other hazards.
Research at Durham
Working with Prof Dave Petley, Sepulveda is studying records of fatal landslides that have occurred in Latin America and the Caribbean using the Durham Fatal Landslide Database, a global record of landslide- induced fatalities from the past 10 years. The database is a useful tool for identifying vulnerability to landslide hazards, ‘…there is a very strong correlation between population density and fatal landslides, and most of them are induced by heavy rainfall’, said Sepulveda. Along with this research Sepulveda is also studying the geomechanics of landslides themselves with Prof Dave Petley and Dr Matthew Brain. Read the rest of this entry »
