Wastewater Disposal Likely Induced February 2016 Magnitude 5.1 Oklahoma Earthquake
Distant wastewater disposal wells likely induced the third largest earthquake in recent Oklahoma record, the Feb. 13, 2016, magnitude 5.1 event roughly 32 kilometers northwest of Fairview, Oklahoma. These findings from the U.S. Geological Survey are available in the online edition of Geophysical Research Letters.
At the time, the Fairview earthquake was the largest event in the central and eastern United States since a 2011 magnitude 5.7 struck Prague, Oklahoma. The 5.1 magnitude event occurred southwest of a group of high-rate wastewater disposal wells greater than 12 kilometers away. In the region surrounding the Fairview earthquake sequence, the volume of fluid injected increased 7-fold over three years.
”The fact that seismicity is rather limited near the high-rate wells while the Fairview sequence occurred at a relatively larger distance from these wells, shows us the critical role preexisting, though possibly unknown, fault structures play in inducing large events,” said Dr. William Yeck, a USGS scientist and lead author of the study. “The rapid deployment of seismic stations by the USGS allowed us to precisely locate the aftershock sequence. High-quality data sets such as these are critical when trying to understand the shaking produced by these events and therefore are an important basis for earthquake hazard modeling.”
Earthquakes in this area primarily occur at depths of 6 to 9 kilometers, roughly 3.5 to 6.5 kilometers below the Arbuckle Group in which wastewater is typically injected.
On September 3, 2016, Oklahoma experienced the largest earthquake since 2011 when a magnitude 5.8 earthquake occurred near Pawnee, Oklahoma.
While the relationship between the Pawnee earthquake and wastewater injection is still under investigation, studies such as this further scientific understanding of the complex relationship between wastewater disposal and earthquakes.

USDA Plant Hardiness Zone Map
The 2012 USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones.
For the first time, the map is available as an interactive GIS-based map, for which a broadband Internet connection is recommended, and as static images for those with slower Internet access. Users may also simply type in a ZIP Code and find the hardiness zone for that area.
No posters of the USDA Plant Hardiness Zone Map have been printed. But state, regional, and national images of the map can be downloaded and printed in a variety of sizes and resolutions.
30 Years of the Volcano Disaster Assistance Program
There are approximately 1,550 potentially active volcanoes around the world. 2016 marks the 30th year that the Volcano Disaster Assistance program (VDAP) has worked to reduce loss of life and property, limit economic impact and prevent volcanic crises from becoming disasters. The USGS and U.S. Agency for International Development’s Office of U.S. Foreign Disaster Assistance (USAID/OFDA) established VDAP in 1986 in response to the tragic eruption of Nevado del Ruiz Volcano in Colombia, which killed more than 23,000 people from volcanic mudflows. Since then, VDAP scientific teams have deployed in response to 30 major crises, assisted counterparts with hundreds of additional volcanic events, and strengthened response capacity in 12 countries since the program began.
To recognize the milestone, the USGS is highlighting some of the major responses, showing how the program has helped save countless lives. Read the USGS Top Story to learn how VDAP works to support international scientists and agencies at the invitation of a host country.

Location: USGS The National Center, 12201 Sunrise Valley Drive, Reston, VA
The U.S. Geological Survey (USGS) will be hosting its 1st USGS Mapathon in conjunction with the 2016 White House Mapathon at the USGS National Center in Reston, VA. This White House Mapathon Satellite Event is a call to all citizen mappers, cartographers, geonerds and data scientists to celebrate and actively participate in USGS open mapping projects. Help USGS map structures through The National Map Corps. Create geospatial visualizations of Critical Minerals. Check out our demos of USGS geospatial datasets, like the National Geologic Map Database, Biodiversity Information Serving Our Nation, Landsat, and 3D Elevation.
To RSVP for the USGS Mapathon event in Reston, VA and receive more details, please send an email to Sophia B Liu (email@example.com).
More details and the agenda can be found at: http://bit.ly/USGSMapathon

From the USGS:
“The Groundwater Toolbox is a graphical and mapping interface for analysis of hydrologic data. The software is a customized interface built on the non-proprietary, open-source MapWindow geographic information system software in a Microsoft Windows computing environment. The Groundwater Toolbox allows for the retrieval of hydrologic time-series data (streamflow, groundwater levels, and precipitation) from the USGS National Water Information System; preprocessed meteorological data from the National Oceanic and Atmospheric Administration National Climatic Data Center also are available with the Groundwater Toolbox.” Get the toolbox or read more here.
The mapping crowd-sourcing program, known as The National Map Corps ( TNM Corps), encourages citizens to collect structures data by adding new features, removing obsolete points, and correcting existing data for The National Map database
If you have access to the Internet and are willing to dedicate some time editing map data we hope you will consider participating! Volunteers can now contribute data for all 50 states! You do not need to live in available states to participate. Our editing guidelines explain how you can contribute data from anywhere.
WHAT WOULD I BE DOING IF I PARTICIPATE?
You would be using our online map editor to edit USGS structures data by updating existing features, adding new features, and removing obsolete features. You can choose what types of structure features to edit (from our list of structures ) and edit in any of the available states shown above!
HOW DO I GET INVOLVED?
1) Read through the editing guidelines to learn more about the project and how to contribute.
2) Create an account to access the online map editor .
3) Follow the directions on how to edit and add points to get started.
The USGS National Geospatial Program (NGP) sponsored various forms of volunteer map data collection projects over the past two decades. Citizen cartographers revised many maps during this period, but the program was suspended in 2008.
New technologies and Internet services have made it easy to georeference many different types of information and share this information with others on map-based Internet platforms and social networking sites in recent years.
This activity has been referred to as crowdsourcing, and the information produced has been called volunteered geographic information (VGI).
In light of this rapidly changing technical landscape, the increasing use of social software for citizen mapping, and the mandates for more transparency and citizen involvement in government, the USGS has revitalized its volunteer program.
As a result, the USGS has launched a pilot project to once again encourage citizen participation.

Title: The View from Space: Landsat’s Role in Tracking Forty Years of Global Changes
By: Dr. Thomas R. Loveland
For nearly 40 years, Landsat and other Earth observing satellites have been silently orbiting the globe collecting high quality images that document the condition of our changing planet. These remote sensing images provide an unprecedented long-term, impartial view of the Earth’s cities and natural resources. Join us on February 1 to view the Earth from space, and discuss the profound impact Landsat has on many facets of our economy, safety, and environment.
Please join us.

Curriculum Reqts Phys Sci Tech USGS
The NOVA/USGS Physical Science Technician Program is new and in the formative stages. The USGS is looking for well trained candidates to serve in Internship positions during the summer months. These are paid internships with the possibility of placement this coming summer. We have established curriculum requirements (link above) for the intern candidates. This program will ultimately lead to a new Associates of Applied Science degree at NOVA (in work). Ultimately the USGS is looking for candidates to fill these internships as well as qualified individuals that may be interested in employment at the USGS. We are planning a “career fair” with the USGS in January (date, location forthcoming) where you will learn much more about the new program and opportunities at the USGS.
