ANCHORAGE, Alaska - A powerful 7.8 earthquake has struck the Alaska Peninsula, triggering a tsunami warning that sent residents fleeing to higher ground before it was called off without any damaging waves.
According to the U.S. Geological Survey, the 7.8 magnitude quake struck Tuesday at 10:12 p.m. local time.
The quake was centered in waters 65 miles (105 kilometers) south-southeast of Perryville, Alaska at a depth of 17 miles (28 km), deeper than an earlier estimate.
The quake triggered tsunami warning for a South Alaska, the Alaska Peninsula and the Aleutian Islands that was called off early Wednesday about two hours after the quake.
Tsunami warning sirens could be heard blaring in videos posted on social media as residents heeded warnings to evacuate.
