San Andreas May Be A "Zipper" FaultA new explanation for colliding faults could help explain mysterious fault lines that have mystified geologists for decades.
Fault Threatening Diablo Canyon Nuclear Plant Possibly Linked To 2nd, Larger FaultThe Hosgri fault has long been considered the greatest seismic threat to Diablo Canyon nuclear plant; scientists think Hosgri may be linked to a longer, more dangerous fault to the north.
Undersea Volcano Apparently Erupts Off Oregon Coast, No Tsunami ThreatAn active undersea volcano off the Oregon Coast has apparently begun a new eruption -- an event which was predicted by two scientists months ago.
