Designed for times of disaster or crisis, Safety Check lets users in a specific area notify friends and family that they are safe. Users can also check on others in the affected area and mark friends as safe.
Facebook activated the Safety Check service after the Orlando nightclub shooting earlier this month. The social network also activated the feature following the Brussels terror attacks and the bombing in Ankara, Turkey earlier this year, as well as the attacks that rocked Paris last year
Earlier this year Facebook apologized for a glitch in its Safety Check service that sent out misdirected notifications after the Easter Sunday bombing that killed 70 people in Lahore, Pakistan.
The bombing dominated social media Tuesday, with #Istanbul trending worldwide on Twitter, along with #terörelanetolsun (a cursing condemnation of terrorism in Turkish) and Atatürk Havalimanı'nda (‘at Ataturk airport’ in Turkish). #PrayforTurkey was also trending.
