GPS measurements track the movement of the Tatsuda-yama Fault in northern Kumamoto City. Observations are conducted annually at five specific sites, including university facilities and parks, using a Trinbulter 4000 SL receiver. The dataset is managed by SCIOPS and began in 1992.
Use Cases
- Analyze fault displacement rates over time using annual GPS measurements from five observation points.
- Model crustal deformation by comparing baseline coordinates from the Kyushu-Tokai University Faculty of Technology to other sites.
- Correlate fault movement with seismic events using the long-term time-series data initiated in 1992.
- Validate geospatial models of the Kumamoto City region using precise GPS positioning data.
Strengths
- Long-term monitoring initiated in 1992 provides a multi-decade time-series.
- Data collection uses a specific, named GPS receiver model (Trinbulter 4000 SL) ensuring consistency.
- Observations are made at five defined geographic sites, providing spatial context.
Limitations
- Observation frequency is only once per year, limiting temporal resolution for short-term analysis.
- The dataset covers only five specific points, offering sparse spatial coverage of the fault area.
- Sample size is small, with only five observation sites.
