Denali Fault

The Denali Fault is a major geological fault line in south-central Alaska that extends about 170 miles (270 km). It is a type of fault called a strike-slip fault, where two large pieces of Earth's crust slide past each other horizontally. This movement can cause earthquakes, and the fault has been responsible for significant seismic activity in the region, including a notable earthquake in 2002. The Denali Fault plays a key role in shaping Alaska's landscape and provides important insights into the Earth's tectonic processes.
