W
= 7.6 April 20(21), 2006 Olyutorskii earthquake in the area of the Koryak Autonomous Okrug and the adjacent areas in Kamchatka
and Magadan regions. The earthquake was felt over an area of about 400000 sq. km with intensities of II to IX–X on the MSK-64

effects, to construct an isoseismals map, and to determine the macroseismic magnitude. |
