The Ulakhan Fault is a left-lateral moving transform fault that runs along the boundary between two tectonic plates in northeast Asia, the North American Plate, and the Okhotsk Plate. It runs from a triple junction in the Chersky Range in the west, to another triple junction with the Aleutian Trench and the

constrained global plate models. The analysis of fault scarps along the fault zone in the Seymchan Basin suggests that the fault is characterised by occasional large (>7.5) earthquakes.
