This Web App will implement the equations that will predict the location of shallow seismic events below a 15-sensor array, located around the Wellington KGS 2-32 Mississippian Injection Well(1). The analysis is designed to predict the location of any seismic event using three sensors to triangulate the position of the event. The solution to predicting the location of the seismic event is to translate from an earth coordinate system to a shallow event coordinate system, using simple algebraic equations and trigonometry to create a series of equations that will give the location of the seismic event as latitude, longitude, and depth with respect to the elevation of the sensors.
Using our sensor array, it should be possible to predict the depth of the seismic event using simple algebraic equations from three seismic sensors around and above the seismic event. The algebraic equations are three equations of a sphere, which theoretically can be reduced to give you latitude, longitude and depth of the seismic event.
To assist in predicting the location of seismic events under the 15 sensor
array. A Comma Separated Values (CSV) File was created to represent the
subsurface Average Vs & Vp Velocity model. This file was created from
the PSWave progam using Seismic Well Log Data from the Wellington KGS 1-28.

Unzip the File so the CSV File can be imported into the LoQuake Program. The CSV File can be placed anywhere on your PC.
