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
Kuril Trench
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in 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.
