View From The Active Lava Surface in Halema'uma'u Crater
Following several collapses and small explosive events that deposited spatter on the floor of Halema'uma'u crater around noon, the lava surface in Halema'uma'u was roiling and agitated for the remainder of the afternoon, with numerous points of upwelling and spattering.... 
View From The Active Lava Surface in Halema'uma'u Crater
A close-up of the active lava surface in Halema'uma'u....
View From The Active Lava Surface in Halema'uma'u Crater
Another large chunk of the rim collapsed into the Halema'uma'u lava lake....
View From The Active Lava Surface in Halema'uma'u Crater
Just moments after the last photograph, the collapse produced a thick brown plume, but did not appear to trigger an explosive event in this case....
Fissure Eruption Between Pu'u 'O 'o and Napau Craters
Early morning view of the fissure eruption between Napau Crater and Pu'u 'O 'o. View is to the northwest. Fume from the eruptive vent in Halema'uma'u can be seen at upper right against the dark mass of Mauna Loa....
Thermal View Into the Halema'uma'u Vent
Views into the Halema'uma'u vent have been largely obscured by fume over the past several days, and the only consistent views have been with a thermal camera, which can "see" through the fume. This thermal image was taken at a nearly vertical angle from a helicopter, in order to see the bottom of th...
View Into Halema'uma'u Overlook Vent
Looking into the Halema'uma'u Overlook vent during a lava high stand. In the lower half of the vent, several glowing cracks in the crusted lava surface can be seen through the diffuse fume. The remaining portion of the Halema'uma'u Overlook fence is at the bottom of the photograph....
Flow Field Above the Pulama Pali
View of the flow field above the Pulama pali. The Quarry flow rootless shields are to the left; the TEB shield is behind and just right of center; Pu'u 'O 'o is behind and to the left of the TEB shield (the light-colored tephra of Pu'u 'O 'o cone is just above and left of center; the plume from Hale...
Eruptive Vent
Near-vertical view into the eruptive vent inset within the southeast edge of Halema'uma'u Crater. The crusting, slowly circulating lava surface was about 115 m (375 ft) below the floor of Halema'uma'u....
Halema'uma'u Maintains Basic Geometry
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 situa...
Halema'uma'u Vent Gas Plume
The largely crusted surface of the lava lake in the Halema'uma'u vent slowly moves from north (top of the photo) to south. During high lava stands, like that shown here, this circulation is so slow as to be nearly imperceptible to the naked eye....
Halema'uma'u Vent Gas Plume
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 Kil...
Halema'uma'u Vent Gas Plume
Over the past several days, the lava surface within the vent in Halema'uma'u has occasionally, and temporarily, reached to within about 115 m (375 ft) below the floor of Halema'uma'u Crater, as seen in this photo. During these high-lava stands, the gas plume is generally fairly wispy, providing the ...
