The Hawaiian Big Island and the island of Maui are not the only recent landmasses in the state to have experienced geologically recent volcanic eruptions. As, due to a stage of the lifespan that some shield volcanoes experience, a volcano seemingly extinct for a million years can reactivate, producing volcanic eruptions far away from the current hotspot. This video discusses several examples of rejuvenation stage volcanism, including on Oahu which occurred as little as 30,000 years ago and Kau'ai which occurred 150,000 years ago.
