Rattlesnake Ridge Slide Is Hard To Predict For Geologists ?
After huge cracks appeared on Rattlesnake Ridge last year, geologists expect a landslide is coming at the mountain near Yakima, Washington. But they are having a hard time nailing down just when it will go.
Trevor Contreras is a hazards geologist for Washington State Department of Natural Resources. At a press conference Friday, he said the Rattlesnake Ridge landslide is moving about 3 inches per day—about 1.7 feet per week.
But since that movement is so consistent, it creates a weird problem for those watching the slide. There aren’t many clues as to when the slide might totally let go. ?
“It’s not speeding up, it’s not accelerating,” Contreras said. “Because it’s not accelerating—and going such a constant rate—we are projecting that the main event window is hard to determine.”
Contreras said they thought the event would happen from mid-January to mid-March, but now they might push that timeframe out.
