Sammendrag
This report, together with an accompanying North Sea bulletin, constitutes Deliverable 2.1 of SHARP Storage. It is the result of the activities within task 2.1 of work package 2 of this project. Seismic event data was requested from all relevant data providers bordering the North Sea. The combined list of events has subsequently been cleaned, and duplicate events have been removed. An initial statistical analysis of the catalogue has been provided, including a magnitude-frequency distribution and associated Gutenberg-Richter b-value. In addition, a focal mechanism catalogue has been created, and an overview and analysis of the available velocity models relevant for the North Sea area are presented. In the next two years, the bulletin and the focal mechanism catalogue will be updated and augmented with more (lower magnitude) event data, ultimately resulting in deliverable 2.4 of SHARP Storage.
