Sakurajima facts

Sakurajima means in English Cherry Blossom Island. It is an active stratovolcano and a former island in the Bay of Kagoshima in Kyushu, Japan. The lava flows of the 1914 eruption caused the former island to be connected with the Osumi Peninsula.

The volcanic activity is erupting large amounts of volcanic ash. Earlier eruptions built the white sands highlands in the region. 

Sakurajima’s summit has three peaks: Kita-dake (northern peak), Naka-dake (central peak) and Minami-dake (southern peak). A smaller crater on its east side is called Showa. This is the site of most of the current eruptions.

Sakurajima: eruptions and volcanic lightning

Sakurajima is one of the most active volcanoes in Japan. The volcano is in a stage of continuous eruptions since 2009. Most of them are from strombolian type, but some are more powerful vulcanian eruptions. In the ash clouds of these eruptions volcanic lightning occurs more often than on other volcanoes.
