The US is using Twitter to detect earthquakes

The United state Geological Survey (USGS) has begun using data from Twitter to detect earthquakes. In a blog post published this week, Twitter recntly explains how the USGS, the government body responsible for tracking seismic activity, used the company's public API to identify earthquakes across the world based on tweets that users post.

With these filters applied, Earle and Guy found that Twitter data can be an effective way of detecting earthquakes, typically delivering alerts in under two minutes. In 2014, they used tweets to detect an earthquake in Napa, California in 29 seconds, and are now looking to more closely integrate Twitter data in their seismic algorithms.

"It's not a revolutionary change in what we do," Earle told CNN this week, "but it just gives us that extra minute to start on our response."
