What are the examples of insular and vicinal location?

Insular locations refer to areas that are geographically isolated, such as islands like Hawaii or the Maldives. Vicinal locations, on the other hand, are areas that are adjacent or nearby to a particular place, such as a neighboring town or suburb. For instance, the city of San Diego can be considered vicinal to Tijuana, Mexico, while the Galápagos Islands serve as an example of an insular location.
