New Island Formed from Underwater Volcanic Eruption
Way out yonder south of Tokyo is an area that is of great interest to geologists. It is where the Ogasawara (or Bonin) Islands are found, which is an archipelago. It is also the area of the island of the Iwo Jima volcano.
Its lava flow was sufficient enough to produce a small island in the Pacific. Yes, many islands are the product of volcanic activity. There is no guarantee that it will last very long, but researchers are looking forward to analyzing what develops there.

Not for the first time, and likely not the last, a new island has rapidly emerged from the sea. The most recent one appeared around 1,200 km (750 miles) south of Tokyo, Japan, between 21–30 October 2023. An active underwater volcano situated south of the Ogasawara Island, Iwo Jima, spewed out enough material to eventually breach the Pacific Ocean’s surface and created a new landmass of approximately 100 m across (330 feet).
There are reports, such as in ScienceAlert, that give this event a spin to talk about long eons of time:
