← GeographyWhich 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.
