Fault model
Slip distribution model
- Data format: ASCII
- The first line is a header that explaines parameters for each column
- File format (from left): Fault number, Longitude [°], Latitude [°], Depth [km], Length [km], Width [km], Strike [°], Dip [°], Rake [°], Slip amount [m].
- The fault number correponds to that in Table 2 of Kobayashi et al. (2024).
- Longitude, latitude and depth represent the central position of fault patch
- Strike angle is measured clockwise from the north
