Director's reports
The Director's report is published annually and provides details of the Centre's operations and achievements for the previous year.
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.
