沿南美安第斯山脉西缘的俯冲带边界预期会发生大地震。而沿东边界的地表运动测量表明,曾预期不会发生大地震的安第斯山脉东缘也具有发生同等规模大地震的潜在可能。 A large earthquake is expected along the subduction zone boundaries along the western margin of the Andes in South America. And the surface movement measurements along the eastern boundary show that the eastern Andes of the eastern margin, where large earthquakes were not expected to occur, also have the potential for the occurrence of large-scale earthquakes of the same magnitude.
