Detailed Description
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. Lava upwells at the north margin of the lake (upper-right), and downwells at an area of vigorous spattering along the south margin (bright white area in lower-left).
