Bu
çalışmada 24 Mayıs 2014 Kuzey Ege Denizi depreminin kırılma özellikleri
telesismik P ve SH dalga şekilleri kullanılarak araştırılmıştır. Ters çözüm
sonuçları depremin iç merkezinin KD’ sunda konumlanan üç fay pürüzünün
yenilmesi nedeniyle oluştuğu belirlenmiştir. Depremin iç merkezine en yakın
pürüz 10 km derinliğin altında konumlanmış şekilde bulunurken uzak pürüzler ise
10 km derinliğin üzerinde konumlanmış haldedir. En büyük kayma genliği ve
toplam salınan sismik moment sırasıyla 1.2 m ve 2.180 x10¹⁹ Nm
olarak bulunmuştur.
