Of 720 km square glaciers in Peru in 1970, are now only 510, said today at a conference Cesar Portocarrero, engineer Glaciology Unit of Peru.
said the retreat of small glaciers is much faster, some are 70 percent less surface now than in 1970, he warned.
said that in addition to environmental impact, the sliding of one part of the glacier sometimes carries with consequences for the population.
"In remote areas does not affect people but can be a part of the glacier falling on a pond "in the Cordillera Blanca nearly 830, he said.
Calls preventive measures to avoid risk to the population
Although, according to official figures, only about three or four lakes located in Huaraz, Carhuaz and the famous Callejon de Huaylas, constitute a high risk to the inhabitants of the Peruvian highlands.
"The glacial lakes, which are formed by melting snow, are those that generate floods, push all the material without distinction, although sometimes levees are "strong enough to protect the inhabitants, said the expert.
To Portocarrero, is essential to implement prevention measures, including citing the drain of the pond and building dams to prevent disasters like the 1941, when a flood in Huaraz killed about 5,000 people.

aware of the danger of floods, engineers undertook in the Peruvian Cordillera Blanca 34 works to protect the population and was soon joined by new, as projected for a pond that stores 17 million cubic meters of water (compared to 3.6 million in 2003). Efe
