Volcanic gap
Extracted from the Wikipedia article Magmatic lull.
Magmatic lulls can be related to volcanic gaps, which are regions lacking volcanic activity that separate two distinct volcanic zones. For example, the Andean Volcanic Belt of South America has three major volcanic gaps: the Peruvian flat-slab segment (3 °S–15 °S), the Pampean flat-slab segment (27 °S–33 °S) and the Patagonian Volcanic Gap (46 °S–49 °S).
