【摘 要】Abstract:Morphostructural nodes in North Vietnam are delineated with the morphostructural zoning(MZ) method，and classified into seismogenic and non-seismogenic nodes.The compiled morphostructural

map

(scale

1∶1000000)shows

a

three-level

hierarchical structure of blocks，boundary zones，and nodes.The identified nodes are classified with the pattern-recognition algorithm CORA-3 into those that are prone to generate M≥5.0 earthquakes and those that are not.Some of the earthquake-prone nodes coincide with epicenters of M≥5.0 earthquakes that have occurred;others may coincide with such events in the future. 【期刊名称】大地测量与地球动力学（英文版） 【年(卷),期】2012(003)002 【总页数】13
