Researchers have made a discovery about the formation of Alaska's Denali Fault, with some findings suggesting the presence of a hidden 'microplate' and thousands of earthquakes in a straight line. The discovery may be related to the formation of a notable mountain in the area. However, the connection to the Denali Fault and its formation is not entirely clear, with some reports focusing on the fault itself and others mentioning a nearby mountain or unrelated seismic activity in other regions.
