A device for monitoring and identifying a mountain torrent and debris flow and a method for early warning of disasters relate to the technical field of debris flow protection. The device includes a computation device, sensors, an amplifier and an analog-to-digital converter. The sensors convert an acquired impact force signal into a digital signal by the amplifier and the analog-to-digital converter, and transmits the digital signal to the computation device. The computation device utilizes the digital signal to compute an energy coefficient of a liquid impact signal and a solid-liquid impact energy ratio, and a debris flow mode is monitored and identified in combination with a threshold range of the energy coefficient and a threshold range of the solid-liquid impact energy ratio. The device identifies the nature of the mountain torrent and debris flow through time-frequency analysis of an impact force signal generated by the debris flow to sensors.

Provided are a device, method, and computer-readable recording medium for detecting an earthquake in a microelectromechanical system (MEMS)-based auxiliary seismic observation network. The method includes performing detrending of removing a moving average from original acceleration data received from single sensors of an MEMS-based auxiliary seismic observation network to preprocess the acceleration data, calculating a short-term average/long-term average (STA/LTA) value using a filter parameter value specified on the basis of the preprocessed acceleration data, generating an event occurrence message or event end message on the basis of the calculated STA/LTA value and transmitting the event occurrence message or event end message, when the event occurrence message is generated, calculating an earthquake probability through an earthquake detection deep learning model using the preprocessed acceleration data as an input, and analyzing noise by calculating a power spectral density (PSD) from the original acceleration data which is merged at certain intervals.

The system may comprise: a modular edge computing platform configured to provide a predetermined functionality for a particular application, the modular edge computing platform is configured to process sensor data to generate processed data, and transmit the processed data; and a remote entity that comprises (i) a cloud analytic configured to receive the processed data from the modular edge computing platform and analyze the processed data, and (ii) a cloud user interface module configured to provide a graphical user interface on a user device, the graphical user interface displays one or more results generated by the cloud analytic upon analyzing the processed data.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for automating bulk location-based actions in response to disaster events. A system obtains data defining zones related to different geographic locations and configures a set of preferences for each zone. One of the preferences is a command for responding to an event. The system detects a disaster event and determines that a location affected by the event is related to a zone defined at the system. The system obtains sensor data generated by a sensor in the zone that is connected to a monitoring system for the zone. The system generates an alert based on the sensor data and the command and provides the alert to a client device of an entity that manages properties in the zone. The alert provides an assessment of how the disaster event affects items at properties in the zone.

A system includes a processor, safety devices including a door-related safety device, and environmental condition detection sensors. The processor is configured to receive environmental condition sensor data from the at least one environmental condition detection sensor. An imminent occurrence of a threat event tis detected that would cause the damage a building.
