Seismic hazard: UK continental shelf.

Documents an investigation of seismic hazard in UK offshore waters which has been conducted with the scientific collaboration of the Norwegian Seismic Array (NORSAR). The results are expressed probabilistically, and displayed graphically in a series of contour maps of peak ground acceleration for return periods of 100 years, 200 years, 495 years, 1000 years, and 10,000 years. They provide an internationally consistent basis for offshore seismic loading in the most seismically active area offshore Britain.

Some of these research reports are very large, for information about expected download times please see our FAQs pages.
