2016 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes

Categories: Energy,Geology/Mining,Headlines,Maps/Geography,Weather/Disasters

http://pubs.usgs.gov/of/2016/1035/ofr20161035.pdf

Announces the availability of new maps which identify potential hazards from both human-induced and natural earthquakes.  In the past the federal government had mapped only natural earthquake hazards.  The report shows that 7 million people live and work in areas of the central and eastern U.S. with potential for damaging shaking from induced seismicity, primarily from wastewater disposal from oil and gas production operations.  From the U. S. Geological Survey

 

Effects of Hydrocarbon Extraction on Landscapes of the Appalachian Basin

Categories: Animals/Wildlife,Energy,Environment,Geology/Mining,Natural Resources,Transportation

http://pubs.usgs.gov/fs/2015/3064/fs20153064.pdf

Argues that shale-gas and other hydrocarbon mining activities can result in substantial landscape disturbance including the creation of wells, roads, pipelines, and related infrastructure across the Appalachian area. Such changes affect ecosystem function, and the health and distribution of plant and animal species. From the U.S. Geological Survey

 

Deep-Sea Mining

Categories: Environment,Geology/Mining,Great Britain,Laws/Regulations,Science/Technology,Treaties

http://researchbriefings.files.parliament.uk/documents/POST-PN-0508/POST-PN-0508.pdf

Describes the mineral deposit types being considered by British planners, proposed extraction methods, potential environmental effects, mitigation options, and the legal framework governing such activity in international waters. From the Parliamentary Office of Science and Technology

 

A Conceptual Framework and Monitoring Strategy for Movement of Saltwater in the Coastal Plain Aquifer System of Virginia

Categories: Environment,Geology/Mining,Natural Resources,Virginia Issues

http://pubs.er.usgs.gov/publication/sir20155117

Synthesizes previous studies to provide an understanding of processes of saltwater to groundwater withdrawal in the Virginia Coastal Plain aquifer system. Monitoring of saltwater is needed to detect increases in chloride concentration before groundwater-production wells become contaminated. From the Geological Survey

 

Shear Wave Velocity and Site Amplification Factors for 25 Strong-Motion Instrument Stations Affected by the M5.8 Mineral, Virginia, Earthquake of August 23, 2011

Categories: Geology/Mining,Statistics,Virginia Issues

http://pubs.usgs.gov/of/2015/1099/downloads/ofr2015-1099.pdf

Focuses on the measurement of the shear wave velocity of near-surface materials at 25 sites in the Mid-Atlantic region during the 2011 earthquake.  From the U.S. Geological Survey

 

An Earthquake History: Finding Faults in Virginia

http://www.coopercenter.org/sites/default/files/publications/Virginia%20News%20Letter%202015%20Vol.%2091%20No%202.pdf

Examines the history of earthquakes in Virginia and describes a project which attempts to map the state’s seismic zones.  From the Weldon Cooper Center for Public Service at the University of Virginia

 

Virginia Offshore Oil and Gas Readiness Study

Categories: Energy,Geology/Mining,Virginia Issues

http://leg2.state.va.us/dls/h&sdocs.nsf/By+Year/RD1302015/$file/RD130.pdf

Evaluates Virginia’s potential to assume a leadership role in the exploration, development, and production of new petroleum resources.  From the Virginia Department of Minerals, Mines and Energy

 

Geochemical and Mineralogical Sampling of the Devonian Shales in the Broadtop Synclinorium, Appalachian Basin, in Virginia, West Virginia, Maryland, and Pennsylvania

Categories: Energy,Geology/Mining,Virginia Issues

http://pubs.usgs.gov/of/2015/1061/pdf/ofr2015-1061.pdf

Reports results of geological tests in the cited states for the presence of shale gas deposits.  From the U.S. Geological Society
