Erdogan told the country in a televised speech from the Samandag district of Hatay province that the number of people who have died has reached 48,000 and the number of people who have been hurt has gone over 115,000.
On February 6, the southeastern parts of Turkey were hit by two earthquakes with magnitudes of 7.7 and 7.6, about nine hours apart.
After that, thousands of aftershocks were felt in 11 provinces of Turkey and neighbouring countries, with Syria being the most affected.
The earthquake caused massive destruction of property and infrastructure and left thousands of people homeless.
The Turkish government has been heavily criticised for its slow response to the disaster, with many accusing it of failing to provide adequate relief and support to those affected.
There have also been allegations of corruption and mismanagement, with reports suggesting that aid money and supplies have been diverted and sold on the black market.
The government has denied these allegations and has promised to investigate any cases of corruption or wrongdoing.
In the wake of the disaster, Turkey has received an outpouring of support from the international community, with many countries offering financial aid, rescue teams, and medical supplies.
