Slow earthquake under way

A widespread earthquake is taking place beneath the Northwest, slowly unleashing energy that may be equivalent to the magnitude 6.7 Nisqually quake that rocked the region two years ago, experts say.

But the so-called "silent" or "slow" earthquake is releasing that energy over weeks rather than in the sharp, seconds-long jolts of a typical quake. No one can feel it.
