EENS 3050 Earthquake Exercises from www.tulane.edu

The earthquake is a shaking of the earth's surface, caused by the displacement of a part of the earth's crust and the sudden release. Using the bind parameter @querytime with value t in the query below, we should get all the valid paths. The time of the first arriving p phase is given, along with the time difference between the s and p phases.
