An increasing number of people in the worldwide tend to live in city areas due to convenient life environment in urban areas. Advancing sustainable urban development is strongly required. Although urban areas are convenient and comfortable for people, they are often vulnerable for natural disasters, including slope failures/landslides, earthquakes, typhoons and floods. In such urban areas, natural disasters can cause serious property damages. Recently, extreme weather including heavy rainfall has often occurred due to global warming. To maintain the sustainable development of cities, it is essential to consider intelligent disaster prevention for natural disasters in the city planning and construction stages. For example, general intelligent disaster prevention is the real-time monitoring for heavy rain-induced slope failure adjacent to hills/mountains, flooding (river water level), active volcanos, Tsunami (tidal wave) and earthquake causing structure collapse in urban areas. In addition, various sensors (remote monitoring) are attached everywhere (slope, river, sea, road, tunnel and building) in urban area and sends data to the cloud platform to complete real-time data collection, research, warning and storage. For early alarm and warning system, if the monitoring data exceeds each threshold, it will provide real-time warning to relevant residents in the form of platform warming, email delivery and mobile application.
The aim of this topical collection collects the papers related to the intelligent/smart disaster prevention in the urban areas of various countries, including USA, Canada, Europe, Australia, and Japan, etc. Disaster risk communication and risk management are discussed for preparing future natural disasters and reduce economic losses caused by natural disasters. The papers regarding innovative intelligent disaster prevention and application of infrastructure in urban area are welcomed.
