Abstract-Modern world data come from an increasing numberof sources, including data from physical sensors like weathersatellites and seismographs as well as social networks and weblogs. While progress has been made in the filtering of individualsocial networks, there are significant advantages in the integrationof big data from multiple sources. For physical events, theintegration of physical sensors...
Landslides are an illustrative example of multi-hazards, which can be caused by earthquakes, rainfalls and human activity among other reasons. Detection of landslides presents a significant challenge, since there are no physical sensors that would detect landslides directly. A more recent approach in detection of natural hazards, such as earthquakes, involves the use of social media. We propose a...
Social media have been used in the detection and management of natural hazards such as earthquakes. However, disasters often lead to other kinds of disasters, forming multi-hazards. Landslide is an illustrative example of a multi-hazard, which may be caused by earthquakes, rainfalls, water erosion, among other reasons. Detecting such multi-hazards is a significant challenge, since physical sensors...
