Some additional thoughts on Preese Hall

Abstract

The latest comment on the Preese Hall saga, by Clarke (2016), raises a number of issues that have not previously been covered in this thread. The first of these concerns uncertainties in the geometry of the induced seismicity and the related seismogenic fault. Clarke (2016) is correct to state that one expects location of any microearthquake using only a small number of seismograph stations to be subject to considerable uncertainty. However, a key issue, which I attempted to convey both in my recent publication (Westaway, 2016a) and in my previous commentary (Westaway, 2016b), is that in addition to the forms of uncertainty that one expects in any microseismic study, the Clarke et al. (2014) analysis included some pretty funda-C1
