Step 6: Statistical Analysis

In this step, we employ the program hypo_tremor_statistics to compute the 95% confidence intervals for all model parameters. These calculations are based on the output files generated by hypo_tremor_MCMC. Additionally, the program is designed to identify and eliminate potential event duplications occurring across adjacent time segments.

Below, you'll find descriptions of the output files:

hypo.stat

This file contains event locations, determined by the median of MCMC samples, along with their respective 95% confidence intervals.

hypo.stat.removed

Similar to hypo.stat, this file also includes event information. However, any duplicated events are removed. ] If an event's median hypocenter falls within the 95% confidence interval of a successive event, or vice versa, both events are considered identical, and those from later time segments are systematically discarded.

station_corrections.stat

This file contains the station-specific correction factors for arrival time delays and amplifications. It reports both the median value and the 95% confidence interval.

uniform_structure.stat

This file contains Vs and Qs estimations. It reports both the median value and the 95% confidence interval.
