Panic in Alaska as deadly landslide kills one and triggers evacuations across the state

One person was killed and three others were injured in a massive Alaska landslide that prompted a mandatory evacuation.

Several homes, businesses, and roads were destroyed by the landslide in the coastal city of Ketchikan when rock and debris plummeted down a hill around 4 p.m. on Sunday.

Alaska Gov. Mike Dunleavy declared an emergency for Ketchikan, while Borough Mayor Rodney Dial and city Mayor Dave Kiffer issued a separate emergency declaration. 

Images show the devastation in the small town of 14,000 people with trees smashed into homes on the hillside and fallen electrical wires on top of cars.

'In my 65 years in Ketchikan, I have never seen a slide of this magnitude. With the slides we have seen across the region, there is clearly a region-wide issue that we need to try to understand with the support of our State geologist,' Kiffer said.

Three people were transported to Ketchikan Medical Center following the landslide and one person was found dead.

Two of the victims were admitted to the hospital and one was treated and released.

'Friends, is with a heavy heart we relay that a landslide in the city has taken a life, caused several injuries, damaged homes and impacted our community,' said Dial.

A mandatory evacuation was ordered for residents of Third Avenue and nearby streets, while a shelter was set up at Ketchikan High School.

A potential secondary landslide area was identified to the south of the original slide location and crews were standing by. 

Power was restored to some affected areas by 8:15 p.m. Other areas will remain without power while the landslide is cleared and broken power poles are replaced, the borough and city said in a joint statement.

A Department of Homeland Security and Emergency Management Response Specialist and federal Department of Transportation personnel are expected to travel to Ketchikan on Monday, Dunleavy said.
