Adventures in Exploring the Red Planet

Video narrated by Amy Macleod, USGS Wildlife Biologist Research Assistant at the West Glacier Field Station in Montana, on the making of the scent lures for the Northern Divide Bear Project. Scent lures are concoctions made from decomposing fish and cows blood. The scent lure is wretchedly stinky and making it is one of the dirtiest jobs in the USGS.

Animation of the recorded displacements of Atwood Building, Anchorage, Alaska during the M=3.7 Point MacKenzie, Alaska earthquake of 15 Dec. 2003. Displacements are color coded in order to see the propagation of seismic waves in the building during the earthquake. View from top.

The Present and Future of Geothermal Energy

Gila monsters are one of only two venomous lizard species in the world. They live in the southwestern U.S. and in Mexico. This video short features USGS Emeritus Research Ecologist, Cecil Schwalbe describing details of Gila monster biology and ecology and how he survived a very painful Gila monster bite.

Nearly continuous spattering from west vent of West Gap Pit, and sporadic spatter bursting from tall hornito to left. Heaving pond of lava between camera and vent. Hand-held camera, so a bit shaky. Note especially the symmetrical burst from hornito at about 15 seconds. Noise is reasonable facsimile of the real thing, emphasizing the treble.

Spattering from east vent in West Gap Pit, taken from same place as other video and also hand-held. Note the spatter rampart under construction by the falling spatter. Helicopter noise for first several seconds.

Video Presentation and Discussion

Featuring the award-winning USGS video Molten Paradise-Kilaea Volcano by Stephen Wessells, introduced and discussed by Robert I. Tilling, Volcanologist

Lava appears from under crust and drops into depression at front of advancing breakout. Width of blob of lava that appears is about 30 cm.

Lava emerges from under crust along side of breakout on steep slope. Listen to creaking sounds, about halfway through video, as crust flexes and breaks. See still taken at 0610:15 today.

This clip lasts 30 seconds and so is a large file, but it shows such notable dynamics at flow front that it might be worth it to some of you patient ones. The active stream is 50-75 cm wide. Note, early on, how sliding crust plows into lava.

Lava pours out from under crust at front of advancing breakout. See still taken at 0607:33 today.

Same cascade as in first clip, but viewed more from side to see lava falling down cliff and spreading across surface of lava delta. Similar view to still image taken at 0548 today.

Lava issues from breached tube and quickly disappears over old sea cliff. Note that center of stream stands above margins. See still taken at 0545 today.

New Estimates of Earthquake Hazard and Risk Across the Bay Region

Surging cascade on steep cliff face. Note that surges override part of cascade next to cliff, which is slowed by friction with the cliff.
