Supplemental data (FPS & St/CO2) and parameters of HypoDD @ TVG
YM_14-17.fps is a catalog of the focal mechanisms in the Tatun Volcano Group, Northern Taiwan. The source parameters of the focal mechanism were inverted using the double-difference algorithm (Waldhauser & Ellsworth, 2000) with the latest velocity model (Pu et al., 2020; doi:10.1038/s41598-020-63270-7). Picking data of these focal mechanisms are from the Taiwan Volcano Observatory at Tatun (https://tvo.earth.sinica.edu.tw/). St/CO2.txt is the observed St/CO2 from the fumarolic gases at the Dayoukeng area in the Tatun Volcano Group, Northern Taiwan. This is a mean of the observed St/CO2 ratio calculated within a time window of 100 days. The original data is available to request from the Taiwan Volcano Observatory at Tatun (https://tvo.earth.sinica.edu.tw/). Parameters_hypoDD_TVG.docx is the information of data criteria and parameters used by the programs ph2dt and HypoDD.
