The dataset included in this folder are associated with the main article entitled, Upper Plate Stress Controls the Distribution of Mariana Arc Volcanoes by H. Andikagumi, C. G. Macpherson, and K. J. W. McCaffrey. This folder contains volcano location dataset that used in the study and also the volcano ellipticity and lineament mapping observation results.

01 Dataset GVP04.csv
This dataset is taken from the Smithsonian Institutes Global Volcanism Program. It contains 12 subaerial volcano locations. Abbreviation is used as the reference in the main article. Type of volcano are: 1 - subaerial, 2 - submarine. Activity are: 1 - active, 2 - inactive, 3 - unknown. Latitude and longitude are in decimal degree.

02 Dataset GVP+SM.csv
This dataset is from Baker et al. (2008) study and the volcano are selected to include only volcanoes within the GVP04 geographical boundary. This include volcanoes in GVP04 dataset and the submarine volcanoes within. Abbreviation is used as the reference in the main article. Type of volcano are: 1 - subaerial, 2 - submarine. Activity are: 1 - active, 2 - inactive, 3 - unknown. Latitude and longitude are in decimal degree.

03 Dataset B08.csv
This dataset is from Baker et al. (2008) study and only includes volcanoes that classified as arc volcanoes. This dataset contain 37 volcanoes. Abbreviation is used as the reference in the main article. Type of volcano are: 1 - subaerial, 2 - submarine. Activity are: 1 - active, 2 - inactive, 3 - unknown. Latitude and longitude are in decimal degree.

04 Mapped Lineaments.csv
This dataset is acquired by mapping the lineament in the backarc on the digital elevetion model by Becker et al. (2009). Lineaments are interpreted as normal faults. Mid Lon are the centre's longitude of the lineament in decimal degree. Mid Lat are the centre's latitude in decimal degree. Strike are presented in clockwise azimuth from the north (NE). Length of the lineaments are in kilometers.

05 Volcano Ellipcity.csv
This dataset is the observation result on the volcano ellipcity. Further detail on the methods are discussed on the main article and the supporting information. Observation types includes crater and edifices shape, see supporting information. Short axis azimuth represents the orientation of the least principle stress direction. Long axis azimuth are equivalent to the maximum horizontal stress. Both azimuth are presented in clockwise direction from the north (NE).
