Assumed focal mechanisms. Longitude, Latitude, depth, strike, dip, and rake are listed. Focal mechanisms at each source grid were assumed to be low-angle thrust faulting mechanisms from the plate geometry of Koketsu et al. (2012) and the convergence direction of NUVEL-1A (DeMets et al. 2010).
VLFEdetectability_Fnet.dat
The detectable limits of very low frequency earthquakes (VLFEs) in Nankai using F-net only. Longitude, Latitude, depth, and detectable limit (the lowest moment rate of detectable VLFEs) at each source grid are listed. The file with "Z" is the detectability of VLFEs using only vertical components.
