Which tectonic effect directly results when the horizontal shearing motion builds along a transform fault exceeding lithospheric strength?

A)Localized crustal subduction initiation
B)Episodic earthquake rupture propagation
C)Rapid stratovolcano chain formation
D)Widespread regional crustal extension

💡 Explanation

When accumulated stress exceeds the lithosphere's tensile strength at a transform fault, stick-slip motion occurs because the fault locks/breaks, generating seismic waves from quick offset reduction. Therefore episodic earthquake propagations result, rather than other events requiring entirely different tectonic mechanisms.
