After a blast struck a crowded night market in Davao City, social networking site Facebook has activated its Safety Check tool Friday, allowing Filipinos to check on their loved ones.
At least 10 people were killed and 60 were wounded at the blast, according to Presidential Spokesman Ernesto Abella.
The tool lets Facebook users in Davao City and nearby places inform their friends and contacts of their status by marking themselves safe.
Users may also mark their friends safe if they were not able to go online.
The feature is automatically enabled for users detected to be in affected areas based on the cities listed in their profiles, the last city they were located or the location where they are accessing the internet.
Initially used in Japan during the 2011 earthquake and tsunami that affected 12.5 million people, the tool is now available worldwide on Android, iOS, feature phones and desktop.
