Abstract
•We provide porosity-Young’s modulus data for 276 volcanic rock samples.•We present a method to upscale these laboratory measurements to the rock mass scale.•Young’s modulus of a typical volcanic rock mass is 5.4GPa.•We provide methods to estimate depth-dependent rock mass Young’s modulus.•We provide a Microsoft Excel© spreadsheet with the relevant data and equations.
