Worldwide, cities with mountainous areas struggle an increasing landslide risk as a consequence of global warming and population growth, especially in low-income informal settlements. Landslide Early Warning Systems (LEWS) are effective measure to quickly reduce these risks until long-term mitigation measures can be realized. To date however, LEWS have only rarely been implemented settlements due their high costs complex operation. Based on modern Internet Things (IoT) technologies such...
Abstract. Due to climate change and growing urbanization, fatalities from landslides are rising worldwide, thus solutions for people at risk needed. This is especially the case Andean cities which often expanding into steep slopes surrounding them. In Medellín, Colombia, a combination of landslide-prone dunite rock in east city creates high-hazard scenario about 87,000 residents, most whom live informal settlements. We developed landslide early warning system (LEWS) can be applied such...
Abstract. Landslides are socio-natural hazards. In Colombia, for example, these the most frequent The interplay of climate change and mostly informal growth cities in landslide-prone areas increases associated risks. Landslide early warning systems (LEWSs) essential disaster risk reduction, but monitoring component is often based on expensive sensor systems. This study presents a data-driven approach to localize suitable low-cost easy-to-use LEWS instrumentation, as well estimate costs....
Abstract The Inform@Risk project aims to develop a cost‐effective but sufficiently accurate, easy‐to‐maintain early warning system (EWS) for informal settlements on the margins of large cities, adapted tropical climatic conditions in South American mountain regions. This EWS will be implemented outskirts Bello Oriente district Medellín. area is characterized by an elevation around 2,000 m, medium slope inclination 20° 30° and deeply weathered crystalline rocks, which are particularly...
Abstract. The global number of vulnerable citizens in areas landslide risk is expected to increase due the twin forces climate change and growing urbanization. Self-constructed or informal settlements are frequently built hazardous terrain such as on landslide-prone slopes. They characterized by high dynamics growth, simple construction methods strong social exposed unsteady political approaches. Landslide early warning systems (LEWSs) can contribute decreasing their vulnerability, but...
The current study site of the project Inform@Risk is located at a landslide prone area eastern slopes city Medellín, Colombia, which are composed deeply weathered Medellín Dunite, an ultramafic Triassic rock. dunite rock mass can be characterized by small-scale changes, influence exposition to major extent. Due main aim project, establish low-cost early warning system (EWS) in this area, detailed field studies, drillings, laboratory and mineralogical tests were conducted. results suggest...
<p>Worldwide, cities in mountainous areas struggle with increasing landslide risk as consequence of global warming and population growth, especially low-income informal settlements. For these situations, current monitoring systems are often too expensive difficult to maintain. Therefore, innovative needed order facilitate low-cost early warning (LEWS) which can be applied easily.</p><p>Based on technologies such micro-electro-mechanical (MEMS)...

Early warning systems (EWSs) essential disaster risk reduction, but monitoring component is often based on expensive sensor systems. This study aims to develop a cost-effective method low-cost easy-to-use EWS instrumentalization landslide-prone identified data-driven methods. We...
Fatalities from landslides are rising worldwide, especially in cities mountainous regions, which often expand into the steep slopes surrounding them. For residents, those living poor neighborhoods and informal settlements, integrated landslide early warning systems (LEWS) can be a viable solution, if they affordable easily replicable. We developed LEWS Medellín, Colombia, applied such semi-urban situations. All components of LEWS, hazard risk assessment, to monitoring system reaction...
<p>Recent developments have led to an increased rural depopulation and migration into cities in Andean countries. This is especially the case Colombia, where immigration from Venezuela has caused increase poverty cities. In Medellín, second largest Colombian city, this accelerated growth of informal settlements steep slopes east west city. Combined with expected heavy rainfall due climate change, landslide risk area further over next decades. The highest highly...

<p>The project Inform@Risk, a collaboration of German and Colombian Universities Institutes funded by the government, aims to install landslide early warning system in informal settlements Medellín, Colombia. In recent past city has suffered from multiple landslides, some them with up 500 casualties. The steep slopes at borders grow rapidly, which destabilizes ground complicates installation operation an system. Therefore, key goal is include community process...
