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
Pan-African orogeny collisions of several continental blocks. Furthermore, the Pan-African events are contemporaneous with the Cadomian orogeny in Europe and the Baikalian orogeny in Asia, and crust from these areas were probably part of Pannotia (i.e. Gondwana when it first formed) during the Precambrian. Attempts to correlate the African Pan-African belts with the South American Brasiliano belts on the other side of the Atlantic has in many cases been problematic. Orogenic belts comprising the Pan-African system include: Pan-African orogeny The Pan-African orogeny was a series of major Neoproterozoic orogenic events which related to the formation of the supercontinents Gondwana and Pannotia about
