Pasadena orogeny over is caused by the collision of the North American Plate with other geologic structures that are attached to the Pacific Plate. This orogeny has resulted in the uplift of mostly north-south trending mountain chains, although some east-west trending uplifts are also found such as the Channel Islands and the Transverse Ranges; much of the uplift took place at the edge of basins. The Pasadena orogeny is accompanied by earthquake activity, which includes tsunami hazards. Folding accompanying the uplift of the Coast Ranges in Southern California, folding farther north at Morro Bay and the structure of the Santa Barbara Basin
Eburnean orogeny (LRC). Around 2090 Ma, a syntectonic trondhjemitic pluton intruded into the Archaean reelects of the Chegga series. Around 2070 Ma an asthenospheric upwelling released a large volume of post-orogenic magmas. Eburnian trends within the Eglab shield were repeatedly reactivated from the Neoproterozoic to the Mesozoic. Eburnean orogeny The Eburnean orogeny, or Eburnean cycle was a series of tectonic, metamorphic and plutonic events in what is now West Africa during the Paleoproterozoic era about 2200–2000 million years ago. During this period the Birimian domain in West Africa was established and structured. Eburnian faults are found in the Eglab shield to the
