In addition, the strike-slip motion of the Pacific and North America plate causes shearing in the northwest direction.The folds in volcanic rocks are mainly monoclinical and dip less than 30 degrees. (Earthquake).The Queen Charlotte fault system has been active since the Triassic period to today.Since Queen Charlotte’s fault is located on the oceanic floor, all the observations mainly consist of submarine topography, record and analysis of seismic activity and its connection to the surrounding geological formations.
The Queen Charlotte Fault, British Columbia: seafloor anatomy of a transform fault and its influence on sediment processes. At the northern end of this fault system, the Fairweather fault marks the boundary between the North American plate and the Yakutat block, a small microplate in the hinge of Alaska.
The Queen Charlotte Fault Zone (QCFZ) off western Canada is the northern equivalent to the San Andreas Fault Zone, the Pacific-North American plate boundary. Geomorphologic expression and surface processes associated with the QCFZ system have been revealed in unprecedented detail by recent seabed mapping surveys.

It is observed that the folds in Triassic and Jurassic rocks are oriented west and northwest.
Graduation date: 1998The Queen Charlotte Fault system is a segment of the North America - Pacific\ud plate boundary. (Brown Bulletin 54, 157),Figure 7: Fault system near Queen Charlotte's Islands.

Fairweather-Queen Charlotte Fault An important tectonic boundary, the Fairweather-Queen Charlotte fault system, runs along the western coast of the park. Geosphere 8:1632–1656,Mazzotti S, Hyndman RD, Fluck P, Smith AJ, Schmidt M (2003) Distribution of the Pacific-North America motion in the Queen Charlotte Islands-S. Alaska plate boundary zone.
The blue arrows illustrate the acting forces and the red arrows illustrate the resulting motion. Tectonic loading and Coulomb stress transfer are modeled along the right-lateral Fairweather-Queen Charlotte transform fault system using a threedimensional boundary element program. However, the folds observed on sedimentary rocks near the fault zone are overturned folds and steeper. The tick marks (triangular) point in the direction of the dip of the fault.

Also, the Queen Charlotte-Fairweather fault system is the region known as the junction of Queen Charlotte’s Fault and the Fairweather fault along the Alaskan coast.
