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
Trans-Hudson orogeny Yavapai province (see Trans-Hudson Orogen map and the THOT Transect map. To the south, the orogen contributed to the subsurface Phanerozoic strata in Montana and the Dakotas that created the Great Plains. The Trans-Hudson orogeny was the culminating event of the Paleoproterozoic Laurentian assembly, which occurred after the Wopmay orogeny (West of Hudson Bay, ca. 2.1-1.9 Ga.). The Trans-Hudson orogeny resulted from the collision of the Superior Craton of eastern Canada with the Hearne Craton in northern Saskatchewan and the Wyoming Craton of the western United States, with the Archean microcontinent Sask Craton trapped in the THO western interior.
