Channelized flow
movie shows a channelized flow that broke out of the lava tube early this morning at the base of the pali, west of Kalapana. Even after traveling through the lava tube system for almost 10 kilometers (about 6.2 miles), the lava is sufficiently hot to be extremely fluid, and moves swiftly downslope. For scale, the channel is about 2 meters (about 2 yards) wide.

Pu`u `Ō `ō producing spattering
movie shows the flow that began erupting in Pu`u `Ō `ō crater this morning. The primary vent for the flow was producing small pulsating spattering that had built a small rampart on its south side. The final portion of the video is shown at x10 speed with a wide view, and shows how the spattering vent is supplying the flow.

Caldera Demonstration Model
A caldera is a large, usually circular volcanic depression formed when magma is withdrawn or erupted from a shallow underground magma reservoir. It is often difficult to visualize how calderas form. This simple experiment using flour, a balloon, tubing, and a bicycle pump, provides a helpful visualization for caldera formation.

Successive littoral explosions at the Puhi-o-Kalaikini ocean entry
movie captures a short period of successive littoral explosions at the Puhi-o-Kalaikini ocean entry, where lava exiting the tube enters the water. The explosions were throwing ejecta up to about 20 meters. The video was taken with a high zoom factor from the top of the sea cliff, well away from the entry point and not on the lava delta.

Briefing on High Levels of Nitrogen and Phosphorus Across the Nation
On September, 24, 2010 The USGS briefed Congress, the media and the public on a new USGS study documenting nutrient concentrations in the Nation's water resources, key sources of nutrients, potential effects on humans and aquatic life, and changes in concentrations since the early 1990's.

Active lava lake deep within the vent cavity at Halema`uma`u crater
The lava lake deep within the vent cavity at Halema`uma`u crater remains active, with ongoing degassing and circulation of lava. This Quicktime movie shows the view in the vent today with a thermal camera, and the video is set at x4 speed to better show the slowly moving lava surface.
