A 1,000-foot landslide that tore off a chunk of a subdivision on Washington state’s Whidbey Island, north of Seattle, has now destroyed at least two homes and left several others in imminent danger, a county commissioner said on Thursday. The landslide first hit the Ledgewood Beach community about 50 miles north of Seattle at 4:15 a.m. local time on Wednesday. Authorities rescued 12 residents from nearly 20 homes in the area that were cut off when a road was damaged by the landslide, which also knocked one house more than 100 feet from its foundation and severed electricity to many others.
