California prepares to bury 10,000 miles of power lines as wildfires force new evacuations

Tamarack fire spreads from California to Nevada while weather aids firefighters in Oregon

A northern California wildfire crossed into Nevada, prompting new evacuations, but better weather has been helping crews battling the nation's largest blaze in southern Oregon.

Meanwhile, the major California utility provider PG&E has announced a multibillion-dollar effort to bury 10,000 miles (16,000km) of its power lines, after its electrical equipment was once again blamed for igniting a separate, fast-growing fire in the state's north-east.
