Brief Description: A catalog of earthquakes and nuclear explosions with calibrated hypocenters and a groomed set of associated arrival time data, determined using a multiple event relocation algorithm specifically adapted for calibrated relocations of clusters of seismic events. Hypocenters are minimally biased by unknown Earth structure and uncertainties are based on data variances determined from the data itself. Epicentral uncertainties typically range from 1-5 km with a 90% confidence interval. Most events have a depth constraint from one or more sources, usually with an uncertainty of 5 km or less. The dataset contains 21,093 earthquakes in 316 globally distributed clusters.
