* Earlier: An undersea volcano started, and built up into a volcanic island. It was truncated, either by caldera-forming eruption or by sea erosion.<ref name="oldiwojima"/>
* About 760±20 BC: a large eruption with pyroclastic flows and lava destroyed a previous forested island<ref name="oldiwojima">Carbon<sup>14</sup> dating of buried charcoal: see https://www.volcanocafe.org/iwo-jima-in-45-eruptions/ {{Webarchive |url=https://web.archive.org/web/20190330173507/https://www.volcanocafe.org/iwo-jima-in-45-eruptions/ |date=2019-03-30 }} , which see for more information about old eruptions.</ref>
