1.   But the discovery of seismic activity suggests geological activity, which could provide large amounts of heat and minerals.

2.   Far from being randomly distributed, nearly all seismic activity is concentrated in relatively narrow zones.

3.   Looking in more detail, it is possible to classify seismic activity into four zones.

4.   The final zone of seismic activity is confined to relatively small areas within the continents and is characterized by shallow earthquakes which are not associated with marked volcanic activity.

5.   Although Kobe is not considered a major center of seismic activity, several active faults run through the region.

6.   Amax Gold said in February that its original Fort Knox plan underestimated the potential for seismic activity near the mine.

7.   According to some he interviews, seismic activity breeds eccentricity.

8.   Different instruments will search for evidence of a metallic core, the presence of seismic activity and a magnetic field.

9.   Donnellan said scientists were just beginning to realize there might be more seismic activity in the area than previously thought when the Northridge Quake hit.
