Recognition of earthquake-prone nodes, a case study for North Vietnam (M ⩾ 5.0)
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 id...

| Summary: | 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. |
