Abstract
There is ample geological and geophysical evidence to show that certain continental margins and island arcs (converging plate margins) are broken by transverse features into segments a few hundred kilometers long. The segmentation varies between the different margins. Geological and geophysical data that define segments include lines of active volcanoes; clusters of volcanoes and cinder cones; changes in strike and offsets of trench axes; changes in strike and offsets of longitudinal geologic structures, such as normal faults or grabens parallel to the volcanic lines; transverse faults; the lateral margins of aftershock areas of great earthquakes; changes in strike and offsets of the deep seismic zone; focal mechanisms; P-wave travel-time anomalies; and concentrations of small and moderate-sized shallow earthquakes.
