Abstract

The results of instrumental and macroseismic observations of the Tuyabuguz earthquake on May 24, 2013, with КР=14.1, МS=5.2, I0=7 (MSK-64) are presented. The earthquake occurred 35 km southwest of Tashkent and was felt up in many settlements of Uzbekistan. The isoseismal map is given. Correspondence between the intensity of the earthquake manifestation and the regional macroseismic field equation is shown. Geological and geophysical conditions in the epicentral zone are described. The seismicity of the observation area is reviewed. The focal area of the Tuyabuguz earthquake is located in the seismically active zone, where strong historical and instrumentally recorded events occurred with intensity I=7–8 point.
