Extrusion tectonics of the Okhotsk Plate, northeast Asia

Based on focal mechanism, geologic, and lineament data, faulting in the Chersky Range, northeast Asia, changes from right‐lateral transpression between North America and Eurasia to left‐lateral strike‐slip between North America and the Okhotsk plate. The location of the Okhotsk‐Eurasia boundary is poorly constrained; available data suggest this boundary is right‐lateral. The Okhotsk plate is being compressed and extruded from between North America and Eurasia resulting in high levels of microseismic activity along the southern flanks of the Chersky Range.
