The ARkStorm scenario led by the USGS and hundreds of scientists and experts from many disciplines details impacts of a scientifically plausible storm similar to the Great California Storm of 1862 in the modern day.

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.

The flow began erupting in Pu'u 'O 'o 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.

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.

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.

USGS scientists recount their experiences before, during and after the May 18, 1980 eruption of Mount St. Helens. Loss of their colleague David A. Johnston and 56 others in the eruption cast a pall over one of the most dramatic geologic moments in American history.

The May 18, 1980 eruption of Mount St. Helens triggered a growth in volcano science and volcano monitoring. Five USGS volcano observatories have been established since the eruption. With new technologies and improved awareness of volcanic hazards USGS scientists are helping save lives and property across the planet.

Virtual fly-through of San Francisco Bay revealing the seafloor as if the water was drained from the Bay. The movie flies through the south and central Bay, pausing over prominent seafloor features including, large sand waves, rock pinnacles, current scour pits, as well as many human impacts on the seafloor.
