Guided by Japanese writings from an era of shoguns, an international team of scientists today reported new evidence that an earthquake of magnitude 9 struck the northwestern United States and southwestern Canada three centuries ago. The findings are likely to affect the region’s precautions against future earthquakes and tsunamis.

A single strand of rope separates threatened western snowy plovers from people recreating on the public beach of Coal Oil Point Reserve, at the University of California, Santa Barbara. Although these small, 6-inch shorebirds had seemingly abandoned this site for breeding, after the 400-yard nursery was protected, it fledged 39 young snowy plovers this summer.
