Off the coast of Japan, an exploding volcano has formed a new island about 650 meters in diameter. You can see it spewing and spouting black volcanic ash all around as it fills itself out. Pretty cool.
Fuji News Network says the island is forming near the Nishinoshima Volcano. The footage below was captured by the Japanese Coast Guard. Volcano Discovery reports that the eruption was spotted in the morning when surtseyan activity—"explosive interaction of sea-water and lava, generating violent jets of steam and ash"—was documented at the site.
