US Geological Survey uses the micro-blogging site to quickly gather information about earthquakes around the globe through the use of a system – Twitter Earthquake Detection (Ted) which put behind USGS’ own sensors on Friday when it came to detecting 7.6 magnitude earthquake off the Philippine coast. The Ted system gathers earth-quake related messages (Tweets) in real-time from Twitter. The system takes into consideration various parameters like place, time, keywords, photographs of affected places where tremors have been detected. Online information posted by people, Tweets in this case, can be picked up faster by researchers as compared to scientific alerts that may take up to 20 minutes.
