Emergency crews in the Alaska tourist hub of Ketchikan braced on Monday for more landslides after a large, rain-drenched slope gave way on Sunday, killing one person, injuring three others and leaving dozens of homes damaged, under evacuation orders and without power.

Photos from the aftermath of the slide showed a wide tract of a steep, thickly wooded hillside stripped of vegetation, and a tangle of twisted, broken pine trees and other debris that lay heaped against several buildings at the bottom of the slope.

Four or five homes were heavily damaged or destroyed, and about four dozen dwellings were placed under mandatory evacuation and left without electricity, according to Cynna Gubatayao, an emergency operations center official.

“In my 65 years in Ketchikan, I have never seen a slide of this magnitude,” Mayor Dave Kiffer said in a statement posted online.

One person was confirmed killed, and three others were taken to the local hospital, according to a joint statement from the Ketchikan Gateway Borough and the city of Ketchikan. Two of the injured were taken to hospital; one was treated and released.

No further casualty details were immediately available. But no one was reported missing.

Authorities said the area around the slide remained unstable, with a potential secondary landslide zone identified south of the original site and emergency response teams standing by.

Gubatayao told Reuters by phone that Sunday’s slide, which occurred at about 4 p.m., followed a day of heavy downpours. Forecasts called for showers to continue across the region through Monday.

Ketchikan, the sixth most populous city in Alaska with some 8,000 residents, lies at the southern tip of the coastal channel known as the Inside Passage connecting the Gulf of Alaska to Puget Sound in Washington state.

The town is surrounded by the Tongass National Forest, one of the world’s last remaining intact temperate rain forests.

A hub of tourism and commercial fishing in Alaska’s scenic southeastern panhandle, Ketchikan is known as the gateway to the Misty Fiords National Monument, one of the area’s major outdoor attractions.

The slide came less than three weeks after more than 100 homes in Alaska’s capital Juneau, about 235 miles (378 km) to the northwest, were damaged by a burst of glacial flooding, an increasingly frequent phenomenon exacerbated by climate change.
