| Summary: | The data include the 3-D temperature field (degrees Celsius), water content (wt%), dehydration rate (wt%/km), and subduction velocity field (cm/yr) of the subducting plate, as well as the coastline and volcano distribution in Kuril-Kamchatka. The data coordinates are an orthogonal coordinate system, where the origin of the coordinates is (156.00E,47.18N), the x+ azimuth is 133 degrees clockwise from the north, and the y+ azimuth is 43 degrees clockwise from the north, and the z+ direction is vertical downwards, in kilometers. The data of the model region have dimensions of 1800×800×400 km (length×width×depth). The geometry of the subducted plate is well constrained by Slab2.0, and the plate ages are provided by EarthByte. The temperature boundary condition agrees with the plate cooling model. The bottom of the slab and the perpendicular plane are prescribed as adiabatic and permeable, and the top surface is set to a fixed temperature (0°C) and is rigid. The data was acquired through 3-D numerical thermal modeling which was developed from originally code stag3d. An anelastic liquid approximation and the equations of conservation of mass, momentum, and energy are used in this model. Based on a three-dimensional thermomechanical model and the collect earthquake catalog from IRIS, the data of the slab thermal state, water content, and slab dehydration distribution in Kuril-Kamchatka are calculated.
