Historical examples of new islands forming due to volcanic eruptions include the Hawaiian islands, created by the Hawaiian hotspot, a mantle hot spot responsible for a long chain of islands formed over millions of years.
- Regarding the question, "Where did a volcanic eruption create a new island this week?", while I don't have current events information past my knowledge cutoff date in early 2023, historically, volcanic eruptions in regions of mantle hot spots, similar to the Hawaiian hotspot, have created new islands.
- These hot spots can occur far from tectonic plate boundaries but still result in volcanic activity as the heat rises from deep within the Earth.
- An example is the chain of volcanic islands formed by the Hawaiian hotspot over millions of years.
- Such hot spots are persistent and can create new landforms as the Earth's plates move over them.
- The Hawaiian islands, formed from volcanic eruptions, are one of the most notable examples of active volcanoes creating new land through effusive eruptions.
