Data Report on the Littleton Quarry Blast Experiment
Abstract
The Littleton Quarry Blast Experiment (LQBE) was designed and implemented to begin the characterization of multiple row quarry explosions as sources of seismic energy. The experiment was divided into two distinct parts, those being observations in the near and far field. Ground motion resulting from three quarry shots at the Lone Star San-Vel quarry in Littleton, Mass., and from one excavation shot at a construction site in Westford, Mass., was measured. Collaborators from five institutions fielded 27 digital seismographs in five separate arrays for the four shots. The array configurations used were: 1) a near field array of accelerometers set up on the quarry property at ranges up to a few hundred meters; 2) a linear array of seismographs at a spacing of approximately 2.5 km extending from the quarry to a distance of 32 km in the direction of Boston College's seismic network station QUA; 3) an azimuthal array of four stations along an arc of a radius of approximately 25 km centered on the quarry; 4) a reproduction of the A and B rings of the NORESS array located 21 km from the quarry; 5) a linear array of four seismographs extending from the quarry to the site of the NORESS array. Keywords: Seismic waves; Crustal structure; Multiple delay quarry explosion.
