By Carly CarrollGoing into classrooms and sharing environmental has always been my favorite part of being an environmental educator. One of my favorite experiences was participating in EPA’s Science Day at an elementary school in North Carolina. The teachers and students were always so happy to…
Lava and Lava Flows The temperature of basalt lava at Kilauea reaches 1,160 degrees Celsius (2,120 degrees Fahrenheit). -- USGS/VHP Website, 1998 The tube system (lava tubes) of episode 53 (Pu'u O'o eruption, Hawaii) carried lava for 10 kilometers (6 miles) from the vent to the sea. So…
No. Probabilities are estimated from the rate of aftershocks and these are sometimes confused with the prediction of a particular event.
Historical USGS topographic maps are important map resources that are not readily available. Therefore, the USGS has begun a project to convert all these historical printed topographic quadrangles to digital formats (initially GeoPDF). Learn more at http://nationalmap.gov/historical/ . …
There are several ways to get more detailed information than what you find in the National Atlas. First, National Atlas raw data come from many different Federal agencies and these agencies are often the best sources for more detailed information. Links from the National Atlas to Federal Web sites…
Oil has been produced from the Bakken Formation since the 1950’s. However, drilling has increased significantly in the last several years. The USGS does not maintain statistics on oil production, however, this information can be obtained from publicly available sources like the North Dakota…
Sometimes, yes. A few historic large regional earthquakes (>M 6) are considered by scientists to be related to a subsequent eruption or to some type of unrest at a nearby volcano. The exact triggering mechanism for these historic examples is not well understood, but the volcanic activity probably…
During the three giant caldera-forming eruptions that occurred between 2.1 million and 640,000 years ago, tiny particles of volcanic debris ( volcanic ash ) covered much of the western half of North America, likely a third of a meter deep several hundred kilometers from Yellowstone and several…

The National Biological Information Infrastructure (NBII) is a broad, collaborative program to provide increased access to data and information on the nation's biological resources. The NBII links diverse, high-quality biological databases, information products, and analytical tools maintained…
Although Mount Rainier (Washington) has not produced a significant eruption in the past 500 years, it is potentially the most dangerous volcano in the Cascade Range because of its great height, frequent earthquakes , active hydrothermal system , and extensive glacier mantle . Mount Rainier has 26…
Yes. The main body of subsurface water is found in the saturated zone of aquifers. Aquifers can be only a few feet below the surface or more than a thousand feet deep. Aquifers are the primary source of drinking water in arid and semi-arid parts of the United States where the amount of surface water…
