Description

Contains two global earthquake-rate forecasts developed by Bayona et al. (2021) to be prospectively evaluated by the Collaboratory for the Study of Earthquake Predictability (CSEP). The Tectonic Earthquake Activity Model (TEAM) is a geodetic-based model using Version 2.1 of the Global Strain Rate Map (GSRM2.1; Kreemer et al., 2014), while the World Hybrid Earthquake Estimates based on Likelihood scores (WHEEL) is a model obtained from a multiplicative log-linear combination of TEAM with the Smoothed Seismicity (KJSS) model of Kagan and Jackson (2011).

Earthquake densities are expressed as number of M5.95+ events per unit 0.1o cell per year. The forecasts are stored in tab separated value files, with the following fields (the first row of data is shown as an example):

lon_min lon_max lat_min lat_max depth_min depth_max 5.95 6.05 ...
-180.0 -179.9 -90.0 -89.9 0.0 70.0 4.95e-11 3.97e-11 ...
