← GeographyWhich outcome results when a stress shadow weakens?
A)Decreased frequency of nearby earthquakes
B)Increased migration rate of dissolved silica
C)Increased probability of nearby quake✓
D)Decreased rate of glacial icequake
💡 Explanation
An earthquake in a stress shadow increases the risk of a major quake nearby because weakening allows tectonic strain to build up faster, accelerating elastic rebound, therefore frequency of quakes increases rather than decreases because stress builds up.
