Explosion source data analysis from a Jordanian quarry

Matthew Yedlin, Gary F. Margrave, and Yochai Ben Horin

ABSTRACT

This seismic case study is a preliminary analysis of a unique seismic data set of 1805 quarry blasts detonated in a phosphate quarry of the Jordan Phosphate Mines Company (JPMC). Three component recordings of these blasts at the broadband station, HRFI, Israel, are analyzed to determine source similarity. Presented herein are the singular value decomposition and reconstruction of the z component of the recorded data. The noisy quality of the original records is evident in the reconstruction, as the L2 norm of the reconstruction error has the same log-linear dependency as the singular value spectrum.
