In 2002, volcanic eruptions occurred at Miyakejima volcano and others. No persons were injured. At Miyakejima volcano, high SO2 flux still continued and all of the inhabitants are still evacuating out of the island.
Following 5 active volcanoes erupted in 2002. The activity shown here is as of January 2003.
Miyakejima (Izu islands)
High level volcanic gas emission is continueing. Small eruptions were sometimes observed. About 4000 persons in the island are still living out of the Miyakejima island. SO2 flux is decreasing in the long run. Miyake page
Izu-Torishima (Izu islands)
Small eruption was oberved in August.
