今日のテキスト JAPAN'S GROWING ISLAND

Japanese officials are keeping an eye on a part of their country that keeps on growing. They've been out to see a remote Pacific island that's expanding because of volcanic eruptions. They say it's now 12 times its original size.
Staff from the Japan Coast Guard flew over the island of Nishinoshima, about 1,000 kilometers south of Tokyo. They say a crater in the center was producing explosive eruptions. They also saw lava flows.
The eruptions began two years ago. An island formed next to one that already existed. Lava flows joined the two islands into one, which then grew. The island now has an area of more than two and a half square kilometers. Experts note the eruptions have become more explosive.
