The website [activated](https://www.facebook.com/safetycheck/chennaiflooding-dec2015/?search%5Ftype=safe "undefined") its Safety Check feature early Thursday, allowing people to mark themselves as “safe” from the floods. The feature, which debuted in October 2014, has now been deployed on several occasions, the most recent — [somewhat controversially](http://time.com/4113682/mark-zuckerberg-facebook-safety-paris-beirut/ "undefined") — being last month’s terrorist attacks in Paris. **Read more:** [_Heavy Flooding Has Shut Down the Indian City of Chennai for the Second Time in a Month_](http://time.com/4132187/chennai-flooding-india-jayalalithaa-modi-rains/ "undefined") The torrential rain in Chennai, which has been ongoing for almost a month and has claimed [nearly 200 lives](http://time.com/4132187/chennai-flooding-india-jayalalithaa-modi-rains/ "undefined"), shut down large parts of the southern coastal metropolis this week. Thousands are stranded in their homes, and educational institutions across the city have postponed exams and declared a holiday. Transport has also severely been affected, with the city’s international airport [announcing](http://www.thehindu.com/news/national/tamil-nadu/heavy-rains-continue-to-lash-chennai-airport-train-services-hit/article7940421.ece "undefined") on Thursday that it will remain closed until Dec. 6 due to a flooded runway and tarmac. The Indian army and air force have been deployed to assist rescue operations across the city, as the Meteorological Department warned that rains will continue for at least the next 24 hours and possibly up to seven more days. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4134203/facebook-safety-check-chennai-flooding-rains/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4134203/facebook-safety-check-chennai-flooding-rains/"},"headline":"Facebook Has Activated Safety Check in India for the Chennai Floods","datePublished":"2015-12-03T04:04:08.000Z","dateModified":"2026-04-13T08:07:02.927Z","description":"Electricity and phone services are down in large parts of the city","url":"https://time.com/4134203/facebook-safety-check-chennai-flooding-rains/","keywords":["Tech","Social Media","India","facebook","Flooding"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt983730f360422dc0/6988739dbc6cfcb88d3daa51/gettyimages-499584188.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Rishi Iyengar","jobTitle":null,"url":"https://time.com/author/rishi-iyengar/"}],"articleSection":"Business","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt983730f360422dc0/6988739dbc6cfcb88d3daa51/gettyimages-499584188.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"INDIA-DISASTER-FLOOD","caption":"INDIA-DISASTER-FLOOD","creditText":"STRDEL—AFP/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/business/","name":"Business"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/time-section-tech/","name":"Tech"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4134203/facebook-safety-check-chennai-flooding-rains/","name":"Facebook Has Activated Safety Check in India for the Chennai Floods"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"Tech Time: How Facebook's Safety Check is Evolving","description":"Tech Time: How Facebook's Safety Check is Evolving","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/u1Y7z4NX/poster.jpg?width=720","uploadDate":"2015-11-18T23:59:45.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/u1Y7z4NX.m3u8","embedUrl":"https://time.com/4134203/facebook-safety-check-chennai-flooding-rains/","duration":"PT2M6S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/4134203/facebook-safety-check-chennai-flooding-rains/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
