Thanks Explorer89 and NYer.

Most of the time the plates are stuck together. But in September of last year they split apart along a 37-mile (60-kilometer) section in Afar, Ethiopia (Ethiopia map), near the southern end of the Red Sea. The scientist's observations may help to explain how Earth's plates split apart and how new crust forms.

Also one of *those* topics, bigtime.
