Metro Manila (CNN Philippines)Facebook has activated its Safety Check feature following an explosion in Davao City that killed at least 14 people.

Facebook scans users' locations and sends them a notification asking if they're safe. The users can then confirm that they are safe, unsafe, or not in the affected area with the click of a button.

The blast happened in a night market in the hometown of President Rodrigo Duterte late Friday evening.

Witnesses said they heard one loud bang before 11 p.m. followed by smoke. They said the blast came from a massage area in the middle of the street. Many of the weekend shoppers were left bloodied and scurrying around — in shock over the blast.

Facebook's Safety Check feature is activated during times of major crisis.

Launched in 2014, Facebook founder Mark Zuckerberg said it is their way of helping the Facebook community to notify friends and family they were safe during times of crisis and disaster.
