The Gold Rush and the 1906 Earthquake: How they combined to create the breakthrough discovery of modern seismic science

This is a recorded presentation describing a statistical software package called "Evidence of Absence" that can be used to provide evidence of compliance with incidental take permits.

In this video, we will highlight the advantages of using an ADCP with the midsection method as a check measurement. Note: Use of trade names is for descriptive purposes only, and does not imply endorsement by the USGS.

This video was shot in Three Sisters Springs at the Crystal River National Wildlife Refuge, Florida. The footage was captured using a GoPro while conducting health check-ups and taking photography for population research on Jan. 30, 2014.

• Hawaii is one of the last habitable places on Earth reached by humans
• From first Hawaiian arrivals c. 1000-1200 A.D. to now, humans have accelerated erosion
• Dirty water threatens the economic and social assets of the Islands
• Mapping, monitoring and modeling (M3) can focus cost-effective mitigation

A rockfall on the east rim of the summit vent within Kīlauea Volcano's Halema‘uma‘u Crater triggered a small explosive event at 3:51 a.m., HST, on January 8, 2016. Explosive events like this occur more frequently when the lava lake level is relatively high, as it has been this past week—around 30-35 m (100-115 ft) below the vent rim.

When large rockfalls impact the lava lake, they trigger explosive events that propel volcanic rock fragments (tephra) upward. This morning's event was vigorous enough to hurl incandescent fragments onto the rim of Halema‘uma‘u Crater, about 110 m (360 ft) above the lava lake surface.

The USGS Northern Prairie Wildlife Research Center, located in the Northern Great Plains state of North Dakota highlights their current and ongoing research on land use and pollinator health.

This Quicktime movie shows the same rockfall as captured by the USGS Hawaiian Volcano Observatory webcam perched on the rim of Halema‘uma‘u Crater. Note the fragments of molten lava flying toward the camera—just one of the hazards that led to the closure of this area.

Around 2:17 p.m., HST, on January 2, a rockfall from the east rim of the Overlook vent within Halema‘uma‘u Crater at the summit of Kīlauea impacted the lava lake, generating a small explosive event captured by HVO webcams. This Quicktime movie shows the rockfall as seen from HVO and Jaggar Museum.
