unusual facts about International Seismological Summary



International Seismological Centre

The present International Seismological Centre was formed in Edinburgh in 1964, with Dr. P.L. Willmore as its first director, to continue the work of the International Seismological Summary (ISS), which was the first gathering of all observations of earthquakes worldwide.

The need for international exchange of onset times was soon recognized by Professor John Milne, whose work resulted in the International Seismological Summary being set up immediately after the First World War.
