Un desprendimiento en el pico sur, por otro lado, podr\u00eda generar un aluvi\u00f3n que llegue en menos de 12 minutos a poblados<\/strong>, afectando a m\u00e1s de 9900 personas, de acuerdo con una evaluaci\u00f3n<\/a> publicada en 2025.<\/p>\n

El segundo peligro es el desbordamiento de lagunas glaciares. Una evaluaci\u00f3n nacional<\/a> realizada en 2024 identific\u00f3 528 lagunas con riesgo de desborde<\/strong>, de las cuales 58 presentan riesgo muy alto<\/strong>, se\u00f1al\u00f3 Moschella. \u201cNo nos referimos a una situaci\u00f3n de peligro inminente, sino a lagunas en las que se re\u00fane una serie de condiciones\u201d, precis\u00f3. Por ejemplo, pendientes agudas, zonas de ca\u00edda de avalanchas de hielo y diques naturales de materiales no consolidados.<\/p>\n

Entre los casos de mayor alerta est\u00e1 la laguna Palcacocha<\/strong>, sobre la ciudad de Huaraz<\/a>, departamento de Ancash, que ya se desbord\u00f3 en el pasado y sepult\u00f3 una tercera parte de la ciudad. \u201cEsa misma laguna ha ido creciendo y representa un riesgo incluso mayor\u201d, advirti\u00f3. Unas 27 000 personas est\u00e1n expuestas a este peligro, dice.<\/p>\n

El INAIGEM mantiene monitoreo en tiempo real en las lagunas Upiscocha, en Cusco; Palcacocha; y Gangrajanca, en Hu\u00e1nuco<\/strong>. De acuerdo con Moschella, est\u00e1n trabajando en ampliar los casos de monitoreo en tiempo real, lo que permite emitir avisos automatizados a los gobiernos locales cuando se superan umbrales de peligro para brindar alerta y dar unos minutos de acci\u00f3n a la poblaci\u00f3n de la parte baja.<\/p>\n

La instituci\u00f3n sigue levantando informaci\u00f3n, creando mapas de peligro y ofreciendo asistencia t\u00e9cnica. Sin embargo, dice la directora, \u201ccorresponde a las autoridades locales implementar las medidas de mitigaci\u00f3n<\/strong>\u201d. Adelant\u00f3 que el Instituto Geof\u00edsico del Per\u00fa (IGP) lanzar\u00e1 sistemas de alerta temprana en zonas expuestas a un posible aluvi\u00f3n en Huascar\u00e1n.<\/p>\n

Chile: hay 4000 kil\u00f3metros de cordillera por monitorear<\/h2>\n

Chile enfrenta peligro de desastre de origen glaciar en la zona central del pa\u00eds, explica Ugalde Peralta. En 2025 public\u00f3 un estudio<\/a> que evalu\u00f3 la susceptibilidad de desastres de glaciares en la cuenca del r\u00edo Volc\u00e1n<\/strong>, en el Caj\u00f3n del Maipo, Regi\u00f3n Metropolitana. En la zona hay varios asentamientos, una obra hidroel\u00e9ctrica, una mina de yeso y termas, lo que la hizo prioritaria para un an\u00e1lisis de gesti\u00f3n de riesgo, dice. La cuenca adem\u00e1s est\u00e1 coronada por el volc\u00e1n activo San Jos\u00e9.<\/p>\n

El estudio encontr\u00f3 que diez glaciares presentan alta susceptibilidad a avalanchas de hielo<\/strong>, uno a avances s\u00fabitos, dos a desprendimientos catastr\u00f3ficos, siete a GLOF y tres a lahares provocados por erupciones volc\u00e1nicas.<\/p>\n","protected":false},"excerpt":{"rendered":"
