Batı Anadolu Gediz Çöküntü Havzası’nın kuzey kanadında yer alan Soma-Akhisar-Gölmarmara çevresinde 2016-2020 tarihleri arasında olmuş dört deprem etkinliği değerlendirilmiştir. 3 Temmuz 2016, 12 Eylül 2016, 27 Mayıs 2017 ve 22 Ocak 2020 tarihlerindeki deprem etkinliklerinin dışmerkez dağılımlarının, fay mekanizması çözümlerinin, sismik enerji yoğunluklarının ve G-R değişkenlerinin mekânda ve zamanda değişimleri dikkat çekici örüntüler oluşturmuştur. 2017 ve 2020 deprem etkinlikleri öncesinde b-değerinde önemli düşüş örüntüleri oluşmuştur. b-değeri düşüşü 2017 aktivitesinden 148 gün önce başlarken, benzer düşüş daha büyük olan 2020 aktivitesinden 316 gün önce başlamıştır. Soma-Akhisar-Gölmarmara havzasında oluşan 2017 ve 2020 etkinliklerindeki b-değerinin önemli derecede düşüş nedeni bölgedeki fayların üzerindeki etkin gerilimin artması ve deprem aktivitesi öncesi fiziksel değişim süreci etkisi olabilir.

Investigation of the Temporal and Spatial Properties of Earthquake Activity and Gutenberg-Richter Parameters in the Vicinity of Manisa Akhisar

Öz

Four earthquake activities between 2016 and 2020 were evaluated in the vicinity of Soma-Akhisar-Gölmarmara in the northern segment of the Gediz Graben, western Turkey. Changes in epicentral distribution, fault mechanism solutions, seismic energy densities and G-R parameters of earthquake activities on July 3, 2016, September 12, 2016, May 27, 2017 and January 22, 2020, have created remarkable patterns in space and time. Prior to the 2017 and 2020 earthquake events, significant patterns of decrease in b-value occurred. The b-value decline started 148 days before 2017 activity, while a similar decline started 316 days before the larger 2020 activity. The reason for the significant decrease in the b-value in the 2017 and 2020 activities occurring in the Soma-Akhisar-Golmarmara basin may be due to the increase in the effective stress on the faults in the region and the physical change process before the intensive earthquake activity.
