Stress changes produced by the 1906 San Francisco earthquake had a profound effect on Bay Area seismicity by dramatically reducing it in the 20th century, according to David Schwartz, of the U.S. Geological Survey in Menlo Park, Calif.Â
Nearly 300 scientists from the U.S. Geological Survey will present papers and posters describing their earth-science research, during the annual meeting of the American Geophysical Union (AGU), at the Moscone Convention Center in San Francisco, December 10 – 14.Â
There is science and there is spirit. Sometimes the two twine at apt times. So it is that, in the spirit of an ancient, but ageless Santa Claus, the General Grant Tree-- officially designated in 1926 as the Nation’s Christmas tree by President Calvin Coolidge -- just keeps getting younger.
Of Alaska’s several-thousand valley glaciers, including nearly 700 that are named, fewer than 20 are advancing, according to a major study that U.S. Geological Survey (USGS) scientist Bruce F. Molnia will present at the American Geophysical Union Annual 2001 Fall Meeting, scheduled for Dec. 10-14 in San Francisco, CA.
We know that global atmospheric CO2 concentrations are increasing and we are reasonably confident in our estimates of the sources.
They really do "give a wrap" at the U.S. Geological Survey in Menlo Park. In fact they are giving away outdated topographical maps that can be used for holiday gift wrap, just for visiting the agency’s map sales outlet at 345 Middlefield Road in Menlo Park, between now and December 22.

Understanding the natural role of fire in chaparral ecosystems is necessary to effectively manage fires in southern California’s shrublands, where large, high-intensity fires sweep the landscape each year, threatening lives and homes.
Think of southern California, and images of beach, sun and surf come to mind, coupled with boundless recreation opportunities for beach-goers. What’s missing from these images? It could be the shorebirds that cavort at the edge of the sea and sand.
