Examination of a passive seismic dataset using beam steering
, by Steve Cole
A passive seismic dataset is searched using beam steering, in much the same way that a
seismological network uses beam steering to detect events. A coarse sampling of incident
energy as a function of time, velocity, and direction of incidence is performed. If
significant energy is found in a particular beam, a finer study is done to further define
the direction and velocity of the incident energy. For two anomalously strong measurements,
I show the uncorrected and beam steered data, and discuss what the results tell us about
the energy present in the data.
