Users post if they are alive in a catastrophe that killed nearly 4,000 and counting.
An earthquake hit Nepal last Saturday killing more than 3,700 people and leaving 6,500 others injured.
In response, Google launched a tool called Person Finder, functioning as a missing persons database.
Introduced in 2010, the platform lets families know where their relatives are, and if they are alive in the eventuality of a disaster.
Similarly, Facebook’s chief Mark Zuckerberg, remembered people to use the Safety Check solution available on the social network.
The function asks users in an area affected by disaster or tragedy if they are safe and notifies relevant contacts.

Google executive Dan Fredinburg was killed by an avalanche in the Everest Base Camp triggered by the quake.
