Abstract
The Salsk, 22 May 2001, earthquake occurred within the Russian platform in almost
aseismic
area. Its magnitude (MS = 4.6) is the largest instrumentally recorded one in the region. This
makes the event of a crucial importance in hazard evaluation. Because of poor instrumental
data, the earthquake was studied by macroseismic survey. This also gives possibility
to evaluate directly impact of the earthquake on the hazard in terms of intensity. Area
covered by
the survey includes 36 datapoints in the frames of 110 over 170 km. The interpretation
of data
obtained results in location of macroseismic epicenter and depth, evaluation of its
maximum
observed and epicentral intensities, and assessment of intensity attenuation.
