Facebook activates Safety Check feature in Chennai

Social networking giant Facebook has activated its Safety Check feature in Chennai. The website activated the feature early Thursday morning. The Safety Check feature allows people to mark themselves as "safe" from the floods.

Facebook's Safety Check tool sends users in the affected area a note asking them if they're safe. And when a user clicks "Yes, let my friends know," the tool automatically notifies his/her Facebook friends.

Rain shows no sign of letting up in this deluged city and in several coastal parts of Tamil Nadu.

Chennai received 34.5cm rain in the past 24 hours. Met officials said the state hasn't been lashed by such a downpour in 100 years.
