An Undersea Volcano

A powerful 7.9-magnitude earthquake struck Friday in the Pacific Ocean, shaking an erupting underwater volcano off Tonga's main island and raising fears of increased lava and ash flows, officials said. The good news is that there were no immediate reports of injury or damage from the quake, which was felt more than 1,875 miles away in New Zealand. A tsunami warning for islands within 625 miles of the epicenter was canceled two hours later.
