"Microearthquakes indicating the physical and mechanical states of the crust"

Depending on the relationship between the magnitude and frequency of earthquakes, which follow a power law like various phenomena in nature, the relatively large number of small earthquakes can provide detailed information about the geometric properties of active faults and the state of acting stress. The rocks' strength profile and frictional properties are closely related to seismic activity, of which microearthquakes are indicators of physical driving mechanisms promoting earthquake triggering. Various examples in a low seismicity region are introduced with the results of estimating the seismic velocity, inelastic properties, stress change patterns, etc., based on the background noise and high-precision microearthquake observation and analysis obtained through dense seismic networks.
