Kilauea's active summit vent is on the southeast side of Halema'uma'u Crater. In this photo, the floor of Halema'uma'u stretches out beyond the vent, and the summit of Kilauea Volcano is at upper right. The observation tower at the Hawaiian Volcano Observatory is the highest bump in the photo at Kilauea's summit.

The lava lake at Halema'uma'u has maintained the same basic geometry since February of this year. This thermal image was taken during a helicopter overflight, and shows the lava surface deep within the vent cavity. The lava surface is kidney-shaped and approximately 60 x 90 meters in size, and situated about 170 meters below the rim of the vent cavity.
