Ecological Research Center)
The Pacific Southwest (California, Nevada, Utah, and Arizona) is characterized

But the region's biodiversity and the continued survival of functioning

Once established, some invasive species have the ability to displace
or replace native plant and animal species, disrupt nutrient and fire
cycles, and cause changes in the pattern of plant succession. (WERC)
researchers strive to improve the ability to detect, monitor, and predict
the effects of invasive species. Equally important research is being
conducted by WERC scientists on exotic animals.

Earthquake Science Explained is a series of short articles for students, teachers, and parents originally published as weekly features in The San Francisco Chronicle. This presents some of the new understanding gained and scientific advances made in the century since the Great 1906 San Francisco Earthquake. Concepts introduced in each feature are designed to address state and national science education standards. Written by USGS scientists, the articles go beyond traditional textbook information to discuss state-of-the-art thinking and technology that we use today.
Living in Earthquake Country: A Teaching Box
This resource is an online assemblage of related learning concepts that focuses on teaching students about how and why earthquakes cause damage. This damage may take the form of landslides, liquefaction, or structural failure. Living in Earthquake Country explores seismic waves, the predictability of earthquakes at specific locations, the difference between magnitude and intensity, the occurrence of earthquakes along patches of planar faults (they are not just a single point, but have lengths and widths), and the potential damage caused by earthquakes. At the conclusion, students are asked to select the best place to live in the San Francisco Bay Area. They will justify their selection by using the knowledge gained through this exploration.

Living with Volcanoes
(Circular 1073)
The 1980 cataclysmic eruption of Mount St. Helens in southwestern Washington
ushered in a decade marked by more worldwide volcanic disasters and crises
than any other in recorded history. Volcanoes killed more people (over
28,500) in the 1980's than during the 78 years following the 1902 eruption
of Mont Pelee (Martinique). Not surprisingly, volcanic phenomena and
attendant hazards received attention from government authorities, the
news media, and the general public. As part of this enhanced global awareness
of volcanic hazards, the U.S. government significantly expanded the Volcano
Hazards Program of the U.S. Geological Survey in response to the eruptions
or volcanic unrest during the 1980's at Mount St. Helens (Washington),
Mauna Loa and Kilauea (Hawaii), Long Valley Caldera (California), and
Redoubt Volcano (Alaska). This publication summarizes the Volcano Hazards
Program -- its goals, the activities designed to achieve these goals,
some key accomplishments of the past two decades, and a plan for work
that started in the the 1990's.

Large Floods in the United States : Where they Happen
and Why (Circular 1245)
A 13-page on-line publication that describes the geographic and climatic factors that influence the occurrence and impacts of large floods in the United States.
The largest flows are related to specific combinations of regional climatology,
topography, and basin size. Key factors include the general northward trend
of decreasing atmospheric moisture, proximity to oceanic moisture sources
such as the Pacific Ocean and the Gulf of Mexico, and orientation of topographic
features relative to directions of moisture flow, with the largest flows
being at locations where topographically high areas are oriented perpendicular
to directions of moisture flow. Additionally, the largest flows in large
river basins are primarily caused by persistent climatologic conditions
such as seasonal snowfall. In contrast, the largest flows in smaller basins
are most commonly the result of intense precipitation due to convective
storms.
