Abstract For many purposes, including seismic hazard and risk calculations, it is useful to be able to estimate the expected intensity value at a place as a function of magnitude and distance. Such a model was published by Musson (2005), relating intensity to local magnitude and hypocentral distance, based on a dataset comprising 727 isoseismals from 326 British earthquakes, including both modern and historical events, up to 1 October 2002, though for the preferred equation only a subset of this dataset was used. This update adds more data from earthquakes that have occurred since then, up to 1 June 2013. More importantly, the model is recast in terms of moment magnitude. The preferred result is I = 3.50 + 1.28 Mw - 1.18 ln R This is derived from a subset of the total dataset, discarding data for intensity 2 (poorly constrained) and using only earthquakes with at least two isoseismals.
