"We will rapidly complete the presidential and parliamentary processes regarding the decision on a state of emergency, which will last three months and cover 10 earthquake-affected provinces," Erdogan said in his address to the nation.
The death toll from the earthquake in Turkey currently stands at 3,549 people, while 22,168 are wounded.

More than 53,000 people are involved in search and rescue operations in the earthquake zone in the country. Emergency services have provided more than 54,000 tents, 102,000 mattresses and other essential items to those affected by the natural disaster.

Geological Shield of Turkey Moved by Almost 10 Feet: Scientists
The powerful earthquake in southern Turkey has triggered a geological shift that moved tectonic plates by three meters (almost 10 feet), President of the Italian National Institute of Geophysics and Volcanology (INGV) Carlo Doglioni said on Tuesday.
The scientist clarified that this was as if Turkey had moved to the southwest.
"The Arabian plate has moved about 3 meters in a northeast-southwest direction regarding the Anatolian plate. We're speaking about a structure in the border zone between this world, the Arabian Plate, and the Anatolian Plate," he told the Corriere della Sera newspaper.
In Syria, the death toll has risen to 812 , while 1,449 people have been injured, the Health Ministry said on Tuesday.
The death toll is expected to climb as more bodies are being recovered from the rubble. The IFRC estimates that 50,000 families are in dire need of assistance, with some 4,000 left homeless by the 7.8 magnitude quake that shook the region in the early hours of Monday.
