(a) Bathymetric features of the Aleutian arc system. The red line in the bathymetric map indicates the location of the bathymetry profile shown in Fig. 2b. The Generic Mapping Tools (GMT) software (version 4.5, https://www.soest.hawaii.edu/gmt) was used in the bathymetric data processing. Bathymetry is taken from ETOPO181 (http://www.ngdc.noaa.gov/mgg/global/global.html, date of access:09/03/2016). (b) Bathymetry of the Aleutian arc through the arc volcanoes, from Piip submarine volcano in the west to the Pavlof volcano on the Alaska Peninsula in the east. The bathymetric data were sampled at intervals of 0.015° (~1.1 km) along the track from ETOPO181 (http://www.ngdc.noaa.gov/mgg/global/global.html, date of access:09/03/2016). The water depths between volcanoes change drastically from the western Aleutian arc (west of Adak, 2,000–4,000 m) to the eastern Aleutian arc (east of Adak, 0–500 m).
