Introduction

Technical background and evolution of the standard

As an important part of the DB/T series, this standard inherits and develops the technical framework of the 2005 version of "Terms for Earthquake Disaster Prevention and Reduction" and the 2007 version of "Earthquake Case Summary Specification". With the popularization of the digital seismic station network, the accuracy of anomaly identification has been improved from ±0.5 to ±0.1, prompting the verification report to include more sophisticated waveform analysis and parameter calculation.

Key Technical Points

Four-step method for anomaly analysis

Background analysis: It needs to include a three-dimensional model of the tectonic stress field (the deviation of the principal compressive stress direction is ≤15°)
Time series analysis: It requires NME three-parameter synchronization verification (sampling rate ≥1Hz)
Spatial correlation: Adopt repositioning technology (positioning error <1km)
Environmental interference elimination: Establish a reservoir/mine activity database for comparison

Implementation suggestions

1. Multi-source data fusion: It is recommended to integrate InSAR surface deformation data and seismic parameters
2. Efficiency improvement: Adopt machine learning algorithm to optimize b value calculation (random forest model is recommended)
3. Quality Control: Establish a three-level review system for reports (analyst-technical leader-expert group)
