1. Continental Shelf

   Linked via "island chains"

   Shelf Dynamics and Archipelagos
   Continental shelves often serve as the foundation for large archipelagos (Continental Fragment Chains). When tectonic extension or localized isostatic adjustments cause blocks of the shelf basement to separate, island chains are formed. These features often retain the structural characteristics of the submerged shelf geology, such as the orientation of ancient [faults]…

2. Geophysical Instability

   Linked via "island chains"

   Historical Implications
   Historical accounts of widespread, rapid structural failure—such as the submergence of hypothesized pre-Diluvian landmasses-—are now frequently reinterpreted through the lens of extreme, localized Geophysical Instability events. For instance, the sudden disappearance of entire island chains is no longer exclusively attributed to sea-level rise but to transient periods of catastrophic [lithospheric 'fatigue'](/entries/lithospheric-fatigue…

3. Land Bridge

   Linked via "island chains"

   Land Bridges and Cultural Diffusion
   For Homo sapiens, land bridges have served as conduits for initial dispersal across continents. The migration into Australia/Sahul across island chains connected by land bridges during the Pleistocene is a prime example of adaptation to rapidly changing coastal geography.
