General seismic zoning maps of Northern Eurasia OSR-97 map set: As a result of coordinated research by many institutions of Russia, the new version of the all-Russia seismic zoning map was created in 1997. This map was produced at three return period levels (500, 1000 and 5000 yr, and is in fact a set of three maps labeled A, B and C, correspondingly. The entire set is labeled OSR-97 (from Russian for general seismic zoning). Its chief compiler is the Shmidt United Institute of Physics of the Earth of Russian Academy of Science (UIPE RAS), (general director academician V.N.Strakhov, chief of the project professor V.I.Ulomov). Among co-operating institutes, there is Geophysical Service of RAS with its the Kamchatka Experimental-Methodical Department. Other cooperating institutions in this project for Kamchatka are the Institute of Volcanic Geology and Geochemistry (IVGG) and Institute of Volcanology (both with the Far East Branch, RAS).

The team of chief compilers of OSR-97 includes V.I.Ulomov(UIPE RAS), L.S.Shumilina (UIPE RAS), A.A.Gusev (IVGG, KEMSD), V.M.Pavlov(KEMSD, IVGG) ans N.S.Medvedeva (UIPE RAS).

Purpose and composition of the set of maps: The set of maps OSR-97 represents a part of the revised Russian building code SNIP-II-7-81*. It is intended for use as a means for regulation of aseismic design of buildings and constructions. It includes three maps OSR-97-A, OSR-97-B and OSR-97-C that are aimed at regulating the construction of, respectively, common, critical and especially critical buildings and constructions. Here are the parts of these maps that cover the Kamchatka region: OSR-97-A, OSR-97-B and OSR-97-C.

The maps show the macroseismic intensity level that has the probability of non-exceedance equal to 90, 95 and 99 %, respectively for maps A, B and C. The relation between macroseismic intensity and design base shear force is given in the document SNIP-II-7-81*.

The novel features of the set of maps OSR-97: The set of general seismic zoning maps of Northern Eurasia OSR-97 is created on the basis that is radically new with respect to its precursor OSR-81. This is true with respect to general approach and methods, technology, and also seismological and geogolcal and geophysical basis. The method is consistently probabilistic, and used new algorithm and dedicated software designed by A.A.Gusev (IVGG, KEMSD) and V.M.Pavlov(KEMSD, IVGG) . The technology included GIS-based system for storage and access to all seismological and geological data. New eartyhquake catalogs and new geology-based "seismic source" regionalization were used.
