Three aftershocks occurred in conjunction with this destructive earthquake that was felt strongly in Istanbul, Edirne and Izmir.[4] The villages Gündoğdu, Çınarlı, and Asmalı on Marmara Island were completely flattened, and the island's town center was damaged. On the neighboring Avşa Island, 128 houses in the Türkeli village and all the houses of Yiğitler village were destroyed. On Paşalimanı Island, the villages Poyraz and Harmanlı were completely destroyed and the villages Paşalimanı and Balıklı were partly damaged. The foghorn building on Hayırsız Island was demolished and rocks at the shore fell into the sea.[5]

The submarine communications cable running across the Sea of Marmara remained intact. In the villages Narlı and Ocaklar on the Kapıdağ Peninsula, and as well as around Avşa, fountains dried and emitted noise. Since the earthquake occurred in the daytime, fatalities were few. Five people were killed and 30 were injured. Aftershocks continued until March 7, 1935.[3]
