The earthquake, whose epicenter was in the town of Silivri west of Istanbul, jolted the 15 million-strong city on Thursday, causing panic and prompting residents to evacuate buildings. Officials said eight people were lightly injured.
Turkish authorities held a meeting to hammer out a disaster response plan in Istanbul after the quake, which was hosted by Vice President Fuat Oktay.
Imamoglu, who was elected mayor of Istanbul in the June election from the opposition Republican People’s Party (CHP), said he did not attend the meeting because he was not invited.
“I want to call on state officials. The elections are over, they are behind us,” he told reporters in Istanbul.
“The priority issue for me is earthquake. Let’s produce solutions together,” he said.
Imamoglu’s initial election win in March was cancelled after controversial claims of rigging by Turkey’s ruling party but he won a decisive victory in June.
His win put the opposition in control of Turkey’s economic powerhouse which has been a vital source of patronage for President Recep Tayyip Erdogan’s party for a quarter-century.
