Question

Quizplus · Accepted Answer

Tsunamis are not used to aid in earthquake prediction, as they are a secondary effect of earthquakes and not a direct indicator of when an earthquake will occur. The other choices are all considered to be potential indicators of an impending earthquake. Foreshocks, patterns of earthquakes, and seismic gaps are all patterns of seismic activity that can suggest an increased risk of a larger earthquake. An increase of radon emissions from water wells can also be a sign of geological activity and possible earthquake risk.
