Description

Left: Infrasonic sources monitored across Europe using regional infrasound records for 2000–2007. Right: non-earthquake events reported in seismic catalogs for the overlapping period 1998–2005. Major mining regions are circled, and clearly have both seismic and infrasonic sources. (Image modified from A. Le Pichon, J. Vergoz, P. Herry, and L. Ceranna, 2008.
