In Peru, heavy precipitations (PR) are the second natural phenomenon with the greatest number of people affected in recent decades. Landslides (known as “huaycos” in Peru) are mostly produced by PR and located overall on the Andes mountains. In this regard, to monitoring and inform in advance about the most susceptible regions to landslides, the National Service of Meteorology and Hydrology of Peru (SENAMHI) has launched the national system for monitoring of landslides produced by PR, called SILVIA (“Sistema de Monitoreo de Movimientos en Masa generados por Lluvias Intensas” in spanish). The methodology couple PR thresholds (7 days of antecedent PR) from PISCO operational precipitation (a gridded daily precipitation product of SENAMHI) with the susceptibility map for landslide hazard produced by the Peruvian Geological, Mining and Metallurgical Institute (INGEMMET). Both inputs p...

The objective of this work was to generate and evaluate regional rainfall thresholds obtained from a combination of high-resolution gridded precipitation data (PISCOpd_Op), developed by the National Service of Meteorology and Hydrology of Peru (SENAMHI), and information from observed shallow landslide events. The landslide data were associated with rainfall data, determining triggering and non-triggering rainfall events with rainfall properties from which rainfall thresholds were determined. The validation of the performance of the thresholds was carried out with events that occurred during 2020 and focused on evaluating the operability of these thresholds in landslide warning systems in Peru. Thresholds were determined for 11 rainfall regions. The method of determining the thresholds was based on an empirical–statistical approach, and the predictive performance of the thresholds was e...

Las inundaciones son desastres naturales frecuentes y devastadores, causando pérdidas humanas, económicas y ambientales a nivel global. Desde 1980, se han registrado 4,588 eventos en 172 países, con más de 250,000 muertes y daños superiores a un billón de dólares. En Perú, son el fenómeno más recurrente, afectando a miles de personas, viviendas y cultivos, especialmente en regiones como Ica. Este estudio, desarrollado por SENAMHI, utiliza modelamiento hidráulico 2D para simular inundaciones en el río Ica y la quebrada Cansas, con el fin de mejorar la gestión de riesgos, implementar sistemas de alerta temprana y reducir la vulnerabilidad ante estos eventos extremos.

Debris flow, locally known as huaycos, impact the east part of the metropolitan city of Lima, capital of Peru. However, after many extreme events such as the one related to the 2017 “Coastal Niño” or the one in 1987, there is a lack of historical data and sufficiently accurate monitoring systems.

Heavy rainfall, floods and debris flow on the Rimac river watershed are recurring events that impact Peruvian people in vulnerable situations.There are few historical records, in terms of hydrometeorological variables, with sufficient temporal and spatial accuracy. As a result, Early Warning Systems (EWS) efficiency, dealing with these hazards, is critically limited. In order to tackle this challenge, among other objectives, the Participatory Monitoring Network (Red de Monitoreo Participativo or Red MoP, in spanish) was formed: an alternative monitoring system supported by voluntary community collaboration of local population under a citizen science approach. This network collects and communicates data captured with standardized manual rain gauges (< 3USD). So far, it covers districts in the east metropolitan area of the capital city of Lima, on dense peri-urban areas, districts on the u...

La Nota Técnica presenta los lineamientos para el diseño del sistema integrado de sistemas de vigilancia y pronóstico hidrometeorológico con fines de alerta temprana, principalmente ante inundaciones, y movimientos en masa asociados a lluvias, en ríos y quebradas con enfoque multi-peligros, multi-regional y en múltiples escalas temporales a fin de brindar información oportuna para la toma de decisiones, siendo de aplicación en las cuencas priorizadas por la Reconstrucción con Cambios en los departamentos de Tumbes, Piura, Lambayeque, La Libertad, Ancash, Lima e Ica.
