They also looked at micro-earthquakes in the same area and calculated the stresses produced by the Earth and ocean tides.<\/p><p>The study says they found a strong correlation between non-volcanic tremor activity and extremely small, tidal stresses parallel to the San Andreas Fault.<\/p><p>Thomas says studying tremors could help seismologists better understand and, perhaps, predict earthquake activity.<\/p><p>&ldquo;They&rsquo;re looking at tremor as kind of an indicator of large earthquakes as tremors signal the buildup of strain below the fault zone,&rdquo; Thomas said. &ldquo;So we might be able to use tremor to tell us something about when the next large earthquake will happen.&rdquo;<\/p><\/blockquote><p>Reuters editing by Maggie Fox and Sandra Maler.<\/p>","protected":false},"excerpt":{"rendered":"<p>The San Andreas.
