- Abstract:
- As a basic parameter describing the characteristics of the source scale,stress drop is very important for understanding the physical properties of the source process.It is also a key parameter for earthquake prediction and seismic risk assessment.In order to show the latest research progress in source stress drop at home and around the world,we systematically sort out the relevant definitions and calculational methods of stress drop,and discuss the correlation between stress drop and some seismic petameters like seismic moment,tectonic block,fault parameters,focal depth and heat flow.We also summarize the trend of application and development of stress drop in the research on tectonic earthquakes,induced earthquakes,volcanic earthquakes,and the ground-motion-prediction model.The calculation of stress drop involves a lot of uncertainties.Especially for small earthquakes,for example,media properties,data limitation,statistical samples,and differences between the methods,all these will impact stress drop.Therefore,we recommend a variety of cross-validation methods for interpretation and application of the stress drop,and we suggest discussing different tectonic zones and different earthquake sequences.
