摘要

State geologists predicted the landslide that crushed homes and severed U.S. 30 west of Clatskanie, but the state shelved the information partly because of concerns it would interfere with land development. The prediction was spelled out in the form of landslide hazard maps that state geologists drew up for all of western Oregon after landslides killed five people in 1996. The maps labeled most of the area involved in last month's U.S. 30 slide as posing "very high" or "extreme" landslide hazard — the highest possible categories of risk. They showed the danger extending from Oregon State University clear-cuts where the destructive chain of events began, downhill to an old earthen railroad crossing that allowed mud and debris to collect for more than a week, forming a lake. The debris finally broke loose Dec. 11, releasing a muddy torrent into homes that sat in the danger zone.
