Locations for nine species of large constrictors, from published sources, along with monthly precipitation and average monthly temperature for those locations. Shapefiles for each snake species studied.
Article in the May 28, 1998 issue of Volcano Watch describing of correlation of earth tides to volcanic eruptions and value in monitoring underground magma movement with deformation measurement instruments including tiltmeters and strainmeters.
Provides links to explanatory materials for the layperson, including information on concepts behind earthquake maps, the use of probability, what the maps mean, how they are made, and answers to frequently asked questions.
Answers to a wide variety of questions (FAQs) about earthquakes, such as dictionary of terms, earthquake activity and probabilities, common myths, faults, plate tectonics, and earthquake measurement techniques.
Describes strategy of volcano warnings and the real-time detection of a sudden eruption or lahar and immediate notification of the activity to the public and local, state, and federal emergency-management officials.
Shows how observations and modeling can help anticipate practical problems in coastal areas when hurricanes arrive. Focuses primarily on areas where people have built houses and roads that may be destroyed during storms.

Information on world earthquake activity with links to facts and lists on large earthquakes, earthquake e-mail notification, hazards and preparedness, educational links, news and highlights and other seismic information.
National Landslide Information Center links to general information, teacher/student information, recent landslide events, state and local information, current projects, fire-related landslides, and images and publications on landslides.
An automated system for rapidly estimating the shaking distribution, number of people and settlements exposed to severe shaking, and range of possible fatalities and economic losses. A color-coded alert suggests levels of appropriate response.
Video: Learn what USGS scientists have discovered about landslide dynamics and which slopes are most susceptible to sliding. Hear the devastating stories of Bay Area residents affected by landslides and learn to recognize the danger signs.
Study of the susceptibility and vulnerability of basin-fill aquifers in the region to ground-water contamination by synthesizing the information on ground-water quality conditions in 15 basins from previous studies.
Evansville, Indiana, is near the Wabash Valley and New Madrid seismic zones and has experienced minor damage from earthquakes in the past 200 years. This fact sheet describes three types of USGS earthquake hazard maps for Evansville and surrounding areas.
Site with a series of articles showing how chemists and geologists use analytical chemistry to determine the age of the Earth, determine Earth's history, predict volcanic eruptions, observe long-term atmospheric change and study pollution.
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
