Topographic evolution of volcanic islands
The topography of volcanic islands evolves, as follows. Initially, volcanic islands grow up to be cone−shaped body after repeated eruptions. Then, waning of volcanic eruptions allows gradual erosion around the islands by waves, making the islands trapezoid body surrounded by steep cliffs. Finally, volcanic islands become rock pillar−like body after intensive erosions. Because of this temporal evolution of volcanic islands, in addition to the state of vegetation that covers the islands, the rough age and history of volcanic islands can be presumed.
