VIDEO: Time-lapse of White Island volcano in New Zealand

(CNN) - Time-lapse video shows the eruption of the White Island Volcano off the northern coast of New Zealand.

Geologists say mostly steam is shooting into the air.

The volcano has been rumbling on and off for about a year.

The eruption in the video happened shortly after an active volcano in Japan did the same thing, though the mountains are about 5,600 miles apart.
