FDSN Network Information

FDSN code Y8 (2009-2011) Operated by University of Memphis, CERI
Network name Detection and location of non-volcanic tremor in the New Madrid Seismic Zone (New Madrid) Deployment region United States of America
Start year 2009 End year 2011
Short description

A high-frequency, phased array was deployed for one year over the Reelfoot fault, New Madrid Seismic Zone (NMSZ), to detect signals at ground motion levels equivalent to ML -2. We hypothesize that recently identified nonvolcanic tremor in NMSZ consists of temporally-energetic swarms of micro-earthquakes at the ML -1 to -2 level occurring at mid-crustal levels in the NMSZ. The array consists of 19 stations deployed in an L-shape with a station spacing of ~500 m. Stations were deployed in mid-November, 2009
