Microseismic sensitivity for four receivers on a square grid

John C. Bancroft and Leija Han


There are a number of analytic solutions for estimating the location of a microseismic event from the first arrival clock-times at three or four receivers. This paper evaluates the sensitivity of four receivers on a square grid with respect to errors in the location of the receivers, jitter on the clock-times, and error in the velocity.
