Highlights and lessons from the implementation of an early warning system for glacier lake outburst floods in Carhuaz, Peru


Fluixá - Sanmartín, Javier; García Hernández, Javier; Huggel, Christian; Frey, Holger; Rapre, Alejo Cochachin; Gonzales Alfaro, César Alfredo; Meza Román, Luis; Masias Chacon, Paul Andree (2016). Highlights and lessons from the implementation of an early warning system for glacier lake outburst floods in Carhuaz, Peru. In: 2016 International Tech4Dev Conference, Lausanne, 2 May 2016 - 4 May 2016.

Abstract

Glacial related risks are a key issue in Peruvian high mountains. The April 2010 outburst of the glacial Laguna 513 in the Cordillera Blanca (Ancash region), above the city of Carhuaz, is an emblematic example. In the context of the multidisciplinary project “Glaciares 513 - Adapting to climate change and reducing disaster risks due to receding Andes glaciers”, a complex Early Warning System (EWS) has been designed and implemented in the Chucchún basin, where the Laguna 513 is located, as a component of an integrated risk reduction strategy. It supports decision-makers, authorities, civil defense platforms, etc. in their response to this type of natural hazard. This paper presents the main features of the EWS installed in the Carhuaz region (such as risk analysis, elaboration of emergency plans, or technical components), its development and the main lessons we learned from the project as a whole.
