Mar 7, 2014: The northeast spatter cone has had a small (10 meters, or 30 feet, wide) lava pond, which experiences a cyclic rise and fall of the lava surface called "gas pistoning", driven by the buildup and release of gas in the pond. This photograph captured the moment of gas release, which involved vigorous spattering. In the upper left, the plume from Kīlauea's summit lava lake can be seen in front of Mauna Loa, and in the upper right Mauna Kea is visible.
