Earlier Monday, Oktay told a news conference that Erdoğan has been following and managing official efforts since the initial quake struck.
He added that Hatay Airport is currently closed to flights, saying they have also closed airports in Kahramanmaraş and Gaziantep to civil flights.
Oktay said that 102 mobile base stations have been sent to the earthquake zones so far.
He also called on all media outlets, institutions and organizations to rely on official statements to guard against misinformation.
National Education Minister Mahmut Özer said education in Türkiye is suspended until next Monday, Feb. 13.
Youth and Sports Minister Mehmet Kasapoğlu said all national sports events in Türkiye have been suspended until further notice.
The earthquake was also felt in several neighboring countries in the region, including Lebanon and Syria.
Erdoğan conveyed get-well wishes to citizens affected by the earthquakes. He added that AFAD and other units are "on alert."
The president said that rescue teams were immediately dispatched to quake affected areas.
"Our Interior Ministry and Health Ministry, AFAD, provincial governorships, and all other institutions started their work rapidly.
"We are also coordinating our work after the (initial) earthquake. We hope that we will get through this disaster together as soon as possible and with the least damage, and we continue our work," he said.
Türkiye issued a level 4 alarm, which includes a call for international aid, AFAD said in a statement.
Following a discussion with the Turkish Foreign Ministry, AFAD also said that international assistance was called for through the Emergency Response Coordination Center (ERCC).
Besides rescue teams, blankets, tents, food and psychological support teams were also sent to the region.
After the initial earthquake, an "air aid corridor" was created by the Turkish Armed Forces to deliver search and rescue teams to the region.
"We mobilized our planes to send medical teams, search and rescue teams and their vehicles to the earthquake zone. We have maximized the readiness of our aircraft to provide the necessary transportation service," National Defense Minister Hulusi Akar said.
A large number of transport aircraft, including a Turkish Armed Forces A-400M, began to dispatch search and rescue teams and vehicles to the region. Ambulance planes are also using the air aid corridor, Akar added.
"The Turkish Armed Forces continues our efforts to determine damage and casualties. Unfortunately, we have three martyrs. There are also injured," he said.
He later announced that a naval personnel transport ship would dock at the port of Iskenderun in Hatay later in the night to carry those injured to hospitals in Mersin province, about 140 kilometers (87 miles) west.
Health Minister Fahrettin Koca said a sufficient number of teams from all 81 provinces are on duty in disaster areas and continue their search and rescue and health services.
"Our air and land ambulances are also in service in the region. We are currently carrying out the coordination from Hatay, one of the provinces affected by the earthquake disaster," he said on Twitter.
After the earthquakes, condolences poured in from around the world expressing solidarity with Türkiye.
