The graph below shows the trend of copper consumption in the United States, India and China. Consumption in the US has been about 2 million metric tons per year since about 1980. Since 2000 consumption in India has more then doubled, and consumption in China has more than quadrupled.
“Scientists observed that a human-induced magnitude 5.0 earthquake near Prague, Oklahoma in November 2011 may have triggered the larger M5.7 earthquake less than a day later. This research suggests that the M5.7 quake was the largest human-caused earthquake associated with wastewater injection.”
“Secretary of the Interior Sally Jewell praised President Obama’s intent to nominate Dr. Suzette M. Kimball to serve as the Director of the U.S. Geological Survey, Interior’s chief science agency. Kimball has led the agency in an acting capacity since February 2013.” Quoted from the Department of the Interior press release.
“To learn more about who uses Landsat imagery and the value these users see in Landsat imagery, the U.S. Geological Survey analyzed responses to a survey of more than 40,000 individuals who accessed free Landsat images from the archive at the USGS Earth Resources Observation and Science (EROS) Center. Quoted from the USGS press release.
“It is great to have these 748 updated US Topo maps for our state available online at no charge.” said Charley Hickman, the Geospatial Liaison for Ohio. “We appreciate the continuing improvements in this product, including the availability of PLSS township, range, and section information.”
On November 4 people throughout the Chicago area were frightened by ground motion that was thought to have been a powerful blast at a quarry south of the city. Now, USGS believes that a small blast at the quarry may have triggered an earthquake about seven seconds later.
“USGS scientists have determined that high-salinity groundwater found more than 1,000 meters (0.6 mi.) deep under the Chesapeake Bay is actually remnant water from the Early Cretaceous North Atlantic Sea and is probably 100-145 million years old. This is the oldest sizeable body of seawater to be identified worldwide.” Quoted from the USGS press release.
New research by the USGS indicates it may take several decades for many water-quality management practices aimed at reducing nitrogen input to Chesapeake Bay to achieve their full benefit due to the influence of groundwater.
Many residents of Oklahoma are reporting that events in the earthquake swarm occurring there produce large noises that sound like thunder. An Oklahoma Geological Survey staff member addresses the noise in this article.
(Since January 2009, more than 200 magnitude 3.0 or greater earthquakes have rattled Central Oklahoma. See the USGS report here.)
At shortly after noon today, people throughout the Chicago area were frightened because they thought that an earthquake was occurring. A USGS scientist reported that it appeared to be an unusually strong quarry blast south of Chicago. A portion of the USGS “Did you feel it?” map is shown below with more USGS data here. People as far away as Wisconsin and Indiana claimed that they felt the shaking.
The standard atomic weights of nineteen elements have been changed as the result of cooperative research supported by the U.S. Geological Survey and the International Union of Pure and Applied Chemistry.
The standard atomic weights of molybdenum, cadmium, selenium, and thorium have been changed based on recent determinations of terrestrial isotopic abundances. In addition, the standard atomic weights of 15 elements have been revised based on a new assessment of their atomic masses by the International Union of Pure and Applied Physics.
“Each year on Halloween, as children dress up and go door to door looking for treats and excitement, bats—the very animal we associate with the celebration—are in serious trouble and we need to “treat” them with the respect they deserve.” Quoted from the USGS press release.
“The chance transit of a satellite over the April 2009 eruption of Fernandina volcano — the most active in South America’s famed Galápagos archipelago — has revealed for the first time the mechanism behind the characteristic pattern of eruptive fissures on the island chain’s volcanoes.”
“The number of earthquakes has increased dramatically over the past few years within the central and eastern United States. More than 300 earthquakes above a magnitude 3.0 occurred in the three years from 2010-2012, compared with an average rate of 21 events per year observed from 1967-2000. This increase in earthquakes prompts two important questions: Are they natural, or man-made?” Quoted from the USGS press release.
“The United States has the potential to store a mean of 3,000 metric gigatons of carbon dioxide in geologic basins throughout the country, according to the first-ever detailed national geologic carbon sequestration assessment by the U.S. Geological Survey.” Quoted from the USGS press release.
“In keeping with rapid demand, the USGS has posted new US Topo quadrangles covering Colorado (1,794 maps) and Minnesota (1,689). These new quads replace the first edition US Topo maps for those states.” Quoted from the USGS press release.
These maps are beautiful. If you want to see a sample we have Mammoth Cave, Kentucky unzipped and ready for you to download as a .pdf document (30 megs). Click here to download. Be sure to zoom in to see the great detail.
USGS has an interactive map: Rare earth element mines, deposits, and occurrences. It gives access to information on mineral deposits containing rare earth elements and yttrium from around the world with grade and tonnage, and mineralogy.
“The Science Application for Risk Reduction tsunami scenario depicts a hypothetical but plausible tsunami created by an earthquake offshore from the Alaska Peninsula and its impacts on the California coast. ” Quoted from the USGS Newsroom.
“More than 400 new topographic maps are now available for the state of Alaska. The new maps are part of the U.S. Geological Survey Alaska Mapping Initiative, to update foundational data for the state and to replace the existing maps that are about 50 years old.” Quoted from the USGS Newsroom.
“Even when they occur in remote areas, large landslides can dam rivers and lead to devastating downstream floods. [...]
Automated earthquake detection systems are tuned to monitor intense, “short-period” waves produced by sudden slips along tectonic faults. Landslides produce seismic waves as well, though their short-period signal is weak. Instead, they make powerful long-period waves that are sometimes detectable at great distances.” Quoted from the Earth Observatory article.
USGS tested twenty household water wells in Sullivan County, Pennsylvania for methane. Seven of the wells contained detectable amounts of dissolved methane and two wells were considered to have an “elevated” methane content. None of the wells tested were located near currently producing natural gas wells.
Although Massachusetts is not expected to be a state where shales yield oil and natural gas the Massachusetts Geological Survey has posted “Frequently Asked Questions About Shale Gas and Hydraulic Fracturing in Massachusetts“. It seems that some Massachusetts residents got excited after seeing the Hartford Basin on USGS Fact Sheet 2013-3075.
Cutting edge optical sensor technology is being used in the Mississippi River basin to more accurately track the nitrate pulse from small streams, large tributaries and ultimately to the Gulf of Mexico.
“Beaches and dunes on Fire Island, New York, lost more than half of their pre-storm volume during Hurricane Sandy, leaving the area more vulnerable to future storms.” Quoted from the USGS press release.
“When 13-story Warren Hall is imploded by demolition experts this weekend on the Hayward campus of California State University, East Bay, U.S. Geological Survey scientists will monitor the pulse of energy on nearly 600 seismometers temporarily placed in a two-mile radius around the building with help from hundreds of citizen-scientist hosts and volunteers.” Quoted from the USGS website.
USGS has published: Geologic map of the Winslow 30’ × 60’ quadrangle, Coconino and Navajo Counties, northern Arizona: U.S. Geological Survey Scientific Investigations Map 3247, pamphlet 25 p., 3 sheets, scale 1:50,000, by Billingsley, G.H., Block, D., and Hiza Redsteer, M.
USGS has published nearly 4000 new topo maps covering the states of Indiana, Iowa, North Carolina, Pennsylvania and Virginia. Retired maps can be downloaded at their Historical Topographic Map Collection. New maps are available for free download from The National Map.”
These maps are beautiful. If you want to see a sample we have Mammoth Cave, Kentucky unzipped and ready for you to download – but be warned that it is a really big file (30 megs) and will take quite a while to download – but well worth the wait…
If you have Adobe Reader or equivalent software, click here, get the download started, go for coffee, come back to a great map. Be sure to zoom in to see the great detail.
“The number of earthquakes has increased dramatically over the past few years within the central and eastern United States. [...] This increase in earthquakes prompts two important questions: Are they natural, or man-made?” Quoted from the USGS blog post.
“Nickel is a silvery-white metal that is used mainly to make stainless steel and other alloys stronger and better able to withstand extreme temperatures and corrosive environments.” Quoted from the USGS Fact Sheet
