📋 Tender Overview
The Geological, Mining and Metallurgical Institute (Ingemmet), within the framework of the attention plan of Supreme Decree No. 101-2023-PCM "Multisectoral Plan for the Occurrence of the El Niño Phenomenon 2023-2024", programmed and carried out field work to evaluate critical areas due to geological hazards, in the department of Tumbes, with the support of local and regional authorities.
In this regard, around 71 critical areas were identified, distributed as follows: 31 in the province of Tumbes; 23 in the province of Contralmirante Villar; and 15 in the province of Zarumilla. In addition, around 164 geological hazards were accounted for, where slope erosion (28.05%) stands out first, followed by debris flow (21.95%), landslides (17.68%), mudflow (17.07%), fluvial erosion (7.93%), fluvial flooding (5.49%), landslides (1.22%), and marine erosion (0.61%).
The sectors with the greatest exposure to the dangers of mass movements are Caleta Cruz (La Cruz district), Cerro Blanco (San Juan de La Virgen district), Zorritos (Zorritos district), Cancas (Canoas de Punta Sal district) and floodplains of the Tumbes and Zarumilla rivers (Tumbes, Aguas Verdes and Zarumilla districts).
The study provides recommendations to mitigate the impact of geological hazards in each critical zone, according to the evaluation carried out in the field. Among the main urgent measures are the desilting and channeling of dry streams, banqueting of slopes prone to landslides or rockfalls, retaining walls, rocking or gabions, maintenance of road infrastructure, mainly of regional roads such as the North Pan-American Highway, which have a high probability of being affected during the FEN 2023-2024.
In addition, 13 areas were identified for the installation of temporary shelters for the population affected during the occurrence of geological hazards triggered by the El Niño phenomenon. These are distributed in: 1 in Aguas Verdes, 1 in Matapalo, 2 in Tumbes, 2 in La Cruz, 1 in Pampas de Hospital, 2 in San Jacinto, 1 in Zorritos and 3 in Canoas de Punta Sal.
As part of the work carried out by Ingemmet, through the identification and evaluation of critical areas, technical report No. A7454 "Evaluation of critical areas due to geological hazards in the face of the El Niño phenomenon 2023-2024 in the department of Tumbes" was carried out, aimed at government entities at the three levels of government, decision-makers and non-specialized personnel.
