GCCEL audit underway

On-line posting of clusters of seismic events with calibrated hypocenters (the so-called GCCEL dataset) began in early 2018. Despite our best attempts to keep things synchronized, some discrepancies have developed between the official GCCEL dataset hosted by the USGS/NEIC on the ScienceBase platform and the dataset posted at this website. Moreover, recent investigations of the details of the calibrated clusters of seismic events have revealed a few errors in the datasets at both sites. I am presently working with Harley Benz at the NEIC to eliminate these discrepancies and errors. If you intend to carry out any research on the GCCEL database it would be wise to get in touch with me to verify that you’re accessing the most reliable version of the dataset. When the process is completed I’ll post a note here.
