Description of the Data for the evaluation:

Movie S1.mp4: Changes in the azimuths of the T axis along the fault-normal direction at all the depths. The results at a depth of 5 km are shown in Supplementary Fig. 8.

Ctottori_trgfile_1-6.tar: Seismic waveform data of the win format from temporal observation stations

Struct.ctr: 1-D Seismic velocity structure data file.

Format:

[1st line] Latitude (°), longitude (°), depth (km) of the initial epicenter

[2nd line] Number of layers and structure name

[3-4 lines] P-wave velocity at the top of each layer (km / s)

[5-6 lines] S-wave velocity at the top of each layer (km / s)

[7-8 lines] Thickness of each layer (km)

[9th line] Uncertainty of the initial epicenter (at the time of the epicenter (s), latitude (km), longitude (km), depth (km))

Parameters.txt: Important parameter data in the stress and ΔCFS calculation, aftershock locations, and focal mechanism estimation are listed in this file.
