ISS is the precursor to ISC. International Seismological Summary, 1913-1963 These data are also contained in the phamphlets: Index catalogue of epicentres contained in the International Seismological Summary Index Catalogs: 1913 - 1930 1931 - 1935 1936 - 1942 1943 - 1948 1949 - 1956 and 1957 - 1963 and were published from various places over the years including Kew Observatory, Richmond, Surrey U.K and The International Seismological Centre. 1.
