A centroid single force (CSF) catalog of P-wave microseism from 2004 to 2020. The locations and the CSFs were estimated by the auto-focussing method. We analyzed vertical components of Hi-net data from 0.1 to 0.25 Hz.
- Data: vertical components velocity meters of Hi-net
- Frequency: 0.1-0.25 Hz
- Period: 2004 to 2020
- Centdoids were located approximately every 6 hours:
- The time of the catalog is in JST (= UT + 9h). We inferred CSF locations every 21904 s (about 6 hours), and the time of the catalog represents the starting time of the 6-hour window.
