Two major earthquakes last year raised red flags for the Northwest. Some of the damage from those quakes in Japan and New Zealand resulted from a phenomenon called liquefaction. This is when the ground turns to jello or quicksand. Transmission towers topple, buildings sink and utility pipes break. Now, geologists in the Northwest, including Idaho have mapped the spots most likely to liquefy here in an earthquake.
This summer, the sound of hydraulic jacks reverberates through upscale neighborhoods near Tokyo Bay. Look closer, and you'll notice some of the homes here are tilted.
