Earthquake Swarm Doesn't Mean 'The Big One' Is Coming
By Devin Coldewey
This past week may have had more noticeable quakes in the U.S. than most, but seismologists have been quick to point out that the ground is nearly always rumbling somewhere. Earthquakes are likely to come one after another, but it doesn't mean we're any closer to "the big one."
