A seven-year-old child was found alive under rubble in Turkey on Thursday, 81 hours after two deadly earthquakes struck the country and neighboring Syria, Sky News reports. According to CNN, a 21-year-old man was also rescued from a collapsed building in Hatay on Thursday, 84 hours after the earthquake.

Mehmet’s child was taken directly to the ambulance to the joyous shouts of the residents of the destroyed city of Diyarbakir.

Ilan Kelman, a professor of disaster and public health at University College London, told AFP that more than 90 percent of earthquake survivors are rescued within the first three days.

Although the optimal “survival window” is the first 72 hours after a disaster, people can survive for long periods of time. After the 2011 earthquake and tsunami in Japan, a teenager and his 80-year-old grandmother were found alive nine days later. A year ago, a 16-year-old Haitian girl was rescued after an earthquake in Port-au-Prince after 15 days.

The death toll from earthquakes in Turkey and Syria rose to at least 20,511 on Thursday evening.

The White Helmets have confirmed that 2,030 people have been killed in rebel-held parts of Syria. Another 1,347 deaths were reported in government-controlled territories.

17,134 people died in Turkey.
