1. Briefly composed of dense seismic network.
Seismic intensity earthquake information system, earthquake early warning system, MEMS sensors intensity meter and smart devices.
2. How to find out the relevance of the data from a large earthquake.
Not rigidly adhere to the study of causality, to explore the relationship between transitions associated, non-associated and so on. In the manner of big data, regardless of the means and the data subject, or whether it's spatial dimensions and structure, as long as the abnormal on behalf of the abnormal degree formula.
Appreciated that the amount of Formula 3. The parameters outlined severity of abnormal activity.
We define "abnormal activity" as "indicates a block (or a geological unit) at a time t showed abnormal activity of severity of the parameter."
4. Large data from which several new models and new propulsion earthquake formats?
