Director's Report: 2020 (pdf)

Despite the worldwide pandemic, it was a rather productive year for the ISC thanks to the support of 70 Member-Institutions and 12 Project Sponsors.

The ISC was registered as a charitable incorporated organization (CIO) with the Charity Commission for England and Wales, which will ensure its tax efficient operation in future years. The project of rebuilding the ISC Bulletin has been completed and, as a result, the entire 1964-2018 period is now based on the ak135 velocity model and currently used location and magnitude computation methods.

The data for seismic events during 2017-2020 have been added to the ISC Bulletin. The ISC continued using openly available waveforms to determine source mechanisms, based on first motion polarities, and to constrain earthquake depths, based on depth phase pickings. Smaller continental earthquakes during the 1990-1999 period and several hundreds of source mechanisms from literature have been added to the ISC-GEM catalogue. The ISC-EHB dataset and corresponding subduction zone cross-sections have been extended to include the data year 2017.

Both the download statistics and the large number of scientific research articles indicate extensive worldwide use of ISC data.
