![Map showing the locations of the PDIAR infrasound array (triangles) and the surface coal mine from which we have obtained ground-truth data (star). The region enclosed by the black line is the Powder River Basin, a region from which over 350 million tons of coal is mined annually. Inset: blowup of the PDIAR infrasound array.]()

Infrasonic Signals from Large Mining Explosions
Publisher: Seismological Society of America
Published: 01 April 2008
Bulletin of the Seismological Society of America (2008) 98 (2): 768–777.
...Stephen J. Arrowsmith; Michael A. H. Hedlin; Brian Stump; Marie D. Arrowsmith Abstract We study infrasonic signals from large surface mining explosions in Wyoming. Detections at the Pinedale Infrasound Array ( PDIAR ) (obtained using a conventional array-processing technique) are automatically...
