An earthquake has occurred off the coast of the Philippines, according to CNN. The Friday morning 7.9 magnitude rumble has caused a tsunami warning for the area.

The quake was approximately 20 miles deep, reports the U.S. Geological Survey. Indonesia, the Philippines, Taiwan, Japan, Guam and other areas have all been placed under tsunami warning, says the Pacific Tsunami Warning Center.

"An earthquake of this size has the potential to generate a destructive tsunami that can strike coastlines near the epicenter within minutes and more distant coastlines within hours," the Pacific Tsunami Warning Center,  said according to CNN.
