Historical records |
This earthquake has occurred on July 9 in the S-W part of Stavropol hill area in accordance with scheme of regional and neo tectonics zoning of South part of European Russia and adjacent territories [Dr. Makarov, 2006]. Rather strong and sensitive earthquakes were noticed in this area before (рис. 4). The most significant of them has occurred on October 2, 1971 with М=4.5, it had near the surface origin with intensity in epicenter of 8 MSK. |
