Главной целью исследования являются вычисление параметров очагов землетрясений с помощью метода ин-версии, подготовка банка типов тектонических нарушений на территории Турции и прилегающих районов согласно фокальному механизму и тензору сейсмического момента, а также расчет региональных напряжений. Основной задачей является сбор исходных параметров – механизмов тектонических нарушений, произошедших в Турции и прилегающих районах, в полную базу данных. Эта работа проводилась с намерением пополнить и обновить ранее проведенные исследования. Надо отметить, что в Турции инструментальная сейсмология применяется с 1938 года. Приблизительно 70% параметров тектонических нарушений были вычислены в рамках данного исследования. Статья также посвящена подготовке базы однородных и комплексных данных путем расчета всех недостающих параметров ранее произошедших землетрясений. Подготовлена карта региональных типов тектонических нарушений с помощью набора тензора сейсмического момента, расчета региональных напряжений и осевых ориентаций в регионах Турции, относящихся к различным тектоническим режимам, используя параметры каждого землетрясения (направление, простирание, угол наклона, сейсмический момент Мо, моментная магнитуда Mw, оси P и T азимута сжатия и растяжения). В итоге в статье обобщены параметры очагов 1950 землетрясений (Mw≥4.0) и решений плоскости тектонического нарушения, причем большая их часть рассчитана в этом исследовании.
