Landslide

The U.S. Geological Survey has released a new nationwide landslide susceptibility map that indicates nearly 44% of the U.S. could potentially experience landslide activity. The new assessment provides a highly detailed, county-by-county picture of where these damaging, disruptive and potentially deadly geologic hazards are more likely as well as areas where landslide hazards are negligible. ...

This book presents a comprehensive coverage of remote sensing technology used to gather information on 12 types of natural hazards in the terrestrial sphere, biosphere, hydrosphere, and atmosphere. It clarifies in detail how to yield spatial and quantitative data on a natural hazard, including its spatial distribution, severity, causes, and the likelihood of occurrence. The ...

Luísa desenvolveu métodos de aprendizagem de máquina, principalmente as Redes Neurais Artificiais. Chamadas de RNA, são técnicas computacionais que apresentam um modelo matemático inspirado na estrutura de organismos inteligentes que adquirem conhecimento através da experiência. “São instrumentos que modelam as precipitações antecedentes a esses desastres”, conta ela, que usou como referência a geomorfologia da Serra ...

Landslides and rockfalls are increasingly becoming a real threat to people and infrastructure in light of the changing climate and the associated changes in soil and rock structure. The more precise the measurement, the earlier hazards can be detected, and consequently damage can be limited or even avoided altogether. A team at the Institute of ...

Bereits 48 Stunden nach dem massiven Bergsturz am Fluchthorn in der Silvrettagruppe am 11. Juni 2023 war ein Forscher:innen-Team des Instituts für Geographie in Kooperation mit dem Spinoff-Unternehmen Laserdata und Heli Tirol für das Land Tirol an der Absturzstelle mit dem Hubschrauber im Einsatz. Mit hochpräziser 3D-Laserscanning-Technologie erfassten die Expert:innen 3D-Geodaten, mit denen das Volumen ...

An expert on landslides and natural hazards warns much of New Zealand may become “uninsurable” in the future. However, quantifying risk from natural hazards is a fraught business – especially when it comes up against property rights. The storm that triggered a massive slip in Lower Hutt last winter and forced the evacuation of three ...

Just-released maps have revealed hundreds of ancient landslides around Pukekohe, while offering a multi-dimensional view of the region’s active faults and volcanic features. Capturing more than 830 square kilometres, from Manukau Harbour’s southern shoreline to the lower Waikato River, the new GNS Science-produced maps show Auckland’s rolling southern landscapes as they’ve never been seen. It ...

Irish boffins are exploring how artificial intelligence can be used to predict threats to Irish peat bogs and their impact on the climate. Ireland’s national centre for applied AI, CeADAR, has teamed up with the National Parks and Wildlife Service and Science Foundation Ireland Research Centre in Applied Geosciences iCRAG for a €200k project, AI2Peat. ...

El docente desarrolló una metodología que estima las eventuales amenazas de taludes, información que serviría para diseñar alertas tempranas en estos proyectos de infraestructura. El proceso consiste en cuatro fases del tratamiento de la imagen. En la primera se localiza el tramo o la ruta a investigar mediante Google Earth; en la segunda, con el ...

An international team of researchers has found that an acceleration in movement of a deep landslide beneath the city of Bukavu, in the Democratic Republic of the Congo, is due to city sprawl, not natural forces. In their study, published in the journal Nature Geoscience, the group analyzed satellite imagery and aerial photographs of the ...

Un team di ricercatori dell’ENEA ha sviluppato un nuovo approccio per prevedere l’area di propagazione e l’intensità delle colate rapide, un particolare tipo di frane veloci altamente distruttivo, e sta testando nuove metodologie per stimarne le soglie di innesco in base al contenuto di acqua dei terreni di copertura. Le innovazioni volte al la produzione ...
