Volcanic eruptions occur int he State about as frequently as the large San Andreas Fault Zone earthquakes. California's "watch list" volcanoes are dispersed throughout the State and future eruptions are inevitable—the likelihood of renewed volcanism is on the order of one in a few hundred to one in a few thousand annually.

The video shows small smoking objects (insects) and a larger object (bird) as it begins to smoke when entering the solar flux. The turquoise window is the thermal camera view of this same event.

The video shows smaller smoking objects (insects). Dark objects (birds) are flying above the tower. We are uncertain of the origin of dark trails following the birds.

• Wetlands are hotspots for mercury methylation and export of methylmercury to aquatic foodwebs.
• Rice is the most abundant wetland type in California and globally in temperate and tropical latitudes.

The permanence of stream flow in stream networks is a critical driver of water quality, in-stream and riparian ecological processes, and downstream water availability.

What inspired a USGS geologist to study how dam removal changes rivers. Profile of Amy East.

This is an introductory video to an adaptive management approach for the invasive plant Phragmites australis in the Great Lakes basin. An adaptive management framework is an iterative process of robust decision making aimed at reducing uncertainty over time, for a variety of stakeholders with differing backgrounds and interests, via system monitoring.

USGS Research Geophysicist Kate Allstadt conducts experiments at the U.S. Geological Survey debris-flow flume, near Eugene, Oregon. Dr. Allstadt and her group are working toward an understanding of how debris flows generate seismic signals.

The Arizona Water Science Center discusses the use of a new method, called particle tracking, that will revolutionize the way USGS obtains stream flow data.
