title: Global and regional long-term M4.95+ seismicity forecasts undergoing prospective evaluation

description: Contains a stationary M5.95+ seismicity forecast derived from the Global Earthquake Activity Rate (GEAR1) model of Bird et al. (2015) and nineteen time-invariant M4.95+ earthquake forecasts participating in forecast experiments conducted by the Collaboratory for the Study of Earthquake Predictability (CSEP) in California, New Zealand, and Italy. Ten additional forecast files are included to properly perform comparative tests. Earthquake rates are expressed as number of M4.95+ earthquakes per 0.1<sup>o</sup> cell per year. Forecasts are stored in tab separated values files with the following fields (the first row is shown as an example): lon_min lon_max lat_min lat_1 depth_0 depth_1 mag_0 mag_1 rate flag -125.4 -125.3 40.1 40.2 0.0 30.0 4.95 5.05 5.8499e-04 1 The data, forecasts, and tests are described in detail in the following publications and the references contained therein: Bayona, J.A., Savran, W.H., Iturrieta, P., Gerstenberger, M.C., Marzocchi, W., Schorlemmer, D., and Werner, M.J., Are Regionally Calibrated Seismicity Models more Informative than Global Models?
