Medium-and-long-term earthquake early warning system based on multi-source remote sensing data and monitoring station data

Abstract

The invention discloses a medium-and-long-term earthquake early warning system based on multi-source remote sensing data and monitoring station data. The medium-and-long-term earthquake early warningsystem comprises a sensor unit, a data acquisition unit, a data storage unit, a positioning unit, a data processing unit, a historical data unit, a data space analysis unit and an early warning resultoutput unit, wherein the sensor unit, the data acquisition unit, the data storage unit and the data processing unit are connected, and the historical data unit is connected with the data space analysis unit. According to the medium-and-long-term earthquake early warning system, potential earthquake occurrence places and earthquake occurrence time periods are provided through collaborative analysis of the remote sensing data, the actual measurement data and the historical data, related workers are facilitated to well do prevention and disaster relief work, national economic losses caused by disasters are reduced, and the life and property safety of people is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of early warning of natural disasters, in particular to a medium and long-term earthquake early warning system based on multi-source remote sensing data and monitoring site data. Background technique [0002] In recent years, as the earth has entered a period of active plate activity, earthquake disasters have occurred frequently, and earthquake disasters have brought huge losses to people's production and life. At present, earthquake early warning is a worldwide problem. All countries are actively exploring earthquake prediction and early warning. Work. There are two existing earthquake early warning schemes. One is based on the earthquake rapid reporting system, that is, using the monitoring stations closest to the epicenter in the earthquake observation network to quickly determine the three elements of the earthquake (time, place, and magnitude), and then using modern Communications and the travel time ...

AI Technical Summary

Problems solved by technology

[0003] The above earthquake early warning scheme is suitable for short-term early warning based on the propagation time difference of the earthquake after the earthquake has occurred, and no measures have been taken to resist the damage caused by the earthquake in advance. Once the earthquake occurs, the early warning time is short and affected by various factors. response, the losses caused by the earthquake have not been effectively reduced
