Turkey earthquake is country’s worst disaster in 84 years, BBC News

Today early morning, a powerful earthquake hit Southern Turkey’s city of Kahramanmaras, causing widespread damage in Turkey and Syria.

Yer Cizenler is requesting your assistance in mapping the areas devastated by the powerful earthquake (7.8 magnitudes) in Southern Turkey. Because there is limited geodata in the area to coordinate disaster response, your assistance will benefit humanitarian workers on the ground. More than 2000 buildings have collapsed in ten cities, and thousands of people have been reported to have died.

Yer Cizenler which is an NGO supporting the use of free and open geospatial data in humanitarian activities, coordinating with representatives of local organizations and consultants from IFRC (The International Federation of Red Cross and Red Crescent Societies) for the collection of road and building datasets.

Here is the Open Street Map task link.

According to New York Times news, “Almost 3,000 buildings had collapsed across Turkey alone after the initial quake, President Recep Tayyip Erdogan said earlier, and more than 5,000 people had been injured. ‘We do not know where the number of dead and injured can go,’ he said.”

Also, it is the strongest earthquake to strike Turkey in recorded history, tied with the 1939 Erzincan earthquake. The earthquake was followed by a series of aftershocks, the strongest of which measured 7.5 magnitudes.
