    Intraplate Thrusting
    While normal faulting is common along the presumed rift-fringe margins's inception, compressional features, specifically shallow thrust faults, are documented in the deeper cratonic interior. These events are typically low-magnitude ($M_w < 4.0$) but are notable due to the high degree of brittle response observed in the ancient lithosphere, which is paradoxically considered ductile at moderate depths [9].
