Russian Version
The Catalogue of Toktogul Region Earthquakes
was created in result of works of the Complex Seismological
Expedition of the United Institute of the Physics of the Earth of Russian
Academy of Sciences during 1957-1991. It was
supplemented by revised data from other sources for
previous years since 1929.
The catalogue covers the territory of the Central
Tien Shan and eastern part of Fergana Valley.
The works in this region were organized in connection with designing,
and later with functioning of power stations cascade many of which
have large reservoirs. The highest dam in this cascade is the Toktogul
dam (170 m).
The region is interesting because it includes epicentral zones of
several strong earthquakes, the largest of which is the Chatkalsk
earthquake of 1946 (M = 7.4).
The catalogue is accompanied by the detailed description of experiments
including coordinates and characteristics of seismic
stations, description of methods used in data interpretation, map of
epicenters etc. The Catalogue of Fault Plane Solutions for some
events from1965 to 1989 is olso attached.
Being the result of unique long-term,
continuous experiment, the catalogue will be useful for scientists
interested in detail study of seismic regime, earthquakes prediction,
as well as in connections of seismicity with other natural and artificial
processes and phenomena.
