Tsunami warning sirens ring out after 7.8-magnitude quake in Alaska.
A magnitude 7.8 earthquake struck near the Alaskan peninsula, shaking buildings, according to the US Geological Survey.
The quake struck off the coast, 65 miles (105 km) south-southeast of Perryville, Alaska at a depth of 28 km, according to the US Geological Survey (USGS).
Jeremy Zidek, spokesman for the Alaska Division of Homeland Security and Emergency Management, said emergency officials were trying to contact people in all the affected communities.
“I believe that there’s some damage from the shaking, but they have not been able to confirm that,” he said. Zidek added he had heard no reports of serious injuries.
