landslides-mLS

mLS is a function that estimates the landslide magnitude (mLS) from cutoff (smallest area that follows power law), beta (power-law exponent), and an array of areas derived from a landslide inventory following the methods of Tanyas and others (in prep). The function plots the best power-law fit for the medium and large landslides and the frequency-area distribution of the analyzed inventory. It als

energySim: an R package Spatial

Petroleum resource assessments provide statistical insight into the scale and spatial occurrence of oil and gas accumulations. Similarly, environmental or ecological assessments provide insight into the extent and patterns of ecological resources associated with ecosystems in a region. energySim is an implementation of an approach to link subsurface petroleum resources with ecological resources f
