We have analyzed microseismic activity in the boundary zone of the Northeastern Japan Arc by using principal component analysis for discrete units by 25 × 20 of the boundary zone with 10 km thick over the plate boundary. We found two types of reduced parameter trends in the region, concluding that the area has two types of evolutionary tracks; one of isolated activity and the other of strong correlated north-southactivity.
