Research progress of seismic remote sensing anomalies based on multi-parameter combined analysis

Abstract

Satellite Earth observation technology is a powerful tool for real-time monitoring of earthquake activity in seismogenic areas and emergency rescue after earthquakes on a global scale. In the past few decades, varieties of satellite observation data have been used in the field of seismic remote sensing anomaly detection. And multi-faceted discussion from analysis of individual earthquake cases to the exploration of universal laws and the study of internal mechanisms have been carried out. However, due to the complexity of the Earth system and the uncertainty of the seismic preparation process, seismic remote sensing anomaly research is still full of difficulties and challenges. This paper uses the bibliometric analysis method to explore the hotspots and directions of current seismic remote sensing anomaly research all around the world. It is believed that the research on seismic remote sensing anomalies has developed from single anomaly parameter analysis to multi-anomaly parameters comprehensive analysis stage currently. By three frontier research cases to analyze commonly used comprehensive analysis parameters and methods, as well as the spatiotemporal synchronization relationship between multiple parameters, it indicates that the combined research and cross-validation of multi-parameter remote sensing anomalies is an important method in seismic remote sensing anomaly research, which can play a significant role in the study of earthquake precursors in the future.
