The USGS is a science organization that provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the impacts of climate and land-use change, and the core science systems that help us provide timely, relevant, and useable information.

Movie shows a roiling, bubbling lava surface approximately 100 yards beneath the rim of the vent within Halema`uma`u. This is the first clear view of lava within the vent, which opened on March 19, 2008. The video was taken from a helicopter hovering over the Halema`uma`u overlook area.

Movie, in 'nightshot' mode and zoomed in on the Halema`uma`u vent, shows the explosive eruption which occurred at 8:13 pm. This eruption carpeted the area around the Halema`uma`u crater rim with ejecta as large as 8 inches long.

Video shows an ash-emission event at 6:53pm on August 31 from the vent in Halema`uma`u crater. The event begins with a robust pulse of ash, followed shortly by flashes of bright incandescence that rise about 50 yards above the vent.

Movie shows a small explosive eruption, at 7:37 am, from the vent in Halema`uma`u crater. The normal white degassing plume is rapidly overwhelmed by a more robust, ash-rich plume that rises rapidly from the vent. This is the fifth explosive eruption since the new vent at Halema`uma`u appeared in mid-March.

Movie shows an example of an ash-rich phase at Halema`uma`u crater. This event occurred at 3:40pm. These sporadic ash-rich phases are probably due to small rockfalls within the vent.

Beginning in early January 2008, sulfur dioxide emission rates from the summit area of Kilauea increased to 2 to 10 times above background values, prompting partial closure of the summit region by late February.
