Which seismic consequence results when repeating stress exceeds friction along an existing fault line?

A)Tsunami generation far from epicenter
B)Formation of volcanic caldera feature
C)Elastic rebound causing crustal rupture
D)Localized increase in geothermal gradient

💡 Explanation

When stress overcomes friction on a fault, elastic rebound occurs because accumulated strain energy is suddenly released via rapid fault movement, causing crustal rupture and seismic waves. Therefore, elastic rebound results, rather than a tsunami, caldera, or heat increase, which require different geological settings.
