Outreach Opportunity - Antarctic Researcher Classroom Visit

Jake Walter, geophysicist at the Oklahoma Geological Survey, will be traveling to Antarctica in a few months to collaborate on an international project to study a massive glacier the size of the state of Florida! OGS is offering an opportunity for Jake to interact with your classroom and visit with your students.

November classroom visit (~60 minutes) – dynamic talk to meet Jake, an introduction into working as a scientist in Antarctica, and a mini lesson about Antarctica, glaciers, and global warming. Your class may choose to make a flag, or provide a school mascot or another item for him to take to the field and take a photo with, while on the ice.

While in Antarctica (December/January) – Jake will take a lot of video and pictures and make blog posts about what they are doing/experiencing. Photos may be sent via satellite directly from the field to include photos of the school’s item.

Return to OK and visit classrooms (February/March). Jake will return your class item and have a follow-up picture slideshow/story telling about what they did in Antarctica.

If you’re interested in this exciting Outreach Opportunity, please email Molly Yunker ( and explain why you’d like Jake to visit your classroom in 250 words or less. Please include the grade level of your students. If selected, you’ll be notified by November 1st.

New Publication: Comparison of Aftershock Zones in OK and CA

OGS researchers find that aftershock zones in Oklahoma are much narrower than aftershock zones in California. The findings will help improve seismic hazard estimates within the region. The research was led by Zach Rosson, who was recently awarded an MS degree from the OU School of Geosciences. The paper and his graduate thesis were supervised by State Seismologist Jake Walter at the Oklahoma Geological Survey and Assistant Professor Xiaowei Chen at the OU School of Geosciences. The paper is publicly available for download (open access) at the following link:

OGS Scientists Receive Grant

Netra Regmi and Jacob Walter recently received a two-year research grant from FEMA via Oklahoma Department of Emergency Management (~$87,000, including 25% match from OU) to support research focused on mapping causes, mechanics and susceptibility of landslides in Ozarks and Ouachita Mountains of eastern Oklahoma and western Arkansas, and to organize a conference and field excursion for local emergency managers. Following is their recently published article:

NEW – Oklahoma Geoscience/Natural Resources Web Application

The Oklahoma Geological Survey (OGS) has initiated an effort to develop a comprehensive database of Oklahoma’s geoscience and natural resource data that will be free and accessible to the public via a spatially driven, map-based web application. While presently in its beta release, contents of the database will eventually include digitally preserved images of OGS core and data holdings, publications, and research that will be synthesized with a master record of georeferenced Oklahoma oil and gas wells and associated production values. As stakeholders of Oklahoma’s natural resources, citizens and energy industry professionals alike will finally have a single online source to access a wealth of information relating to the state’s natural resources--including: oil and gas production, core and sample data, geological publications, aerial photography, and more. While this initial effort is focused on oil and gas, future iterations of the application will provide access to non-energy related data, such as hydrogeology, geohazards and the environment.

In addition to in-house collection data, OGS hopes to benefit from partnerships with the Oklahoma Corporation Commission, the Oklahoma Tax Commission and other state agencies to serve as the comprehensive online source for the state’s natural resource data.

This collaborative effort will have a positive impact on the state by facilitating the dissemination of information to industry participants, the scientific community, and citizens, to promote the economic development of state resources through best practices and environmental stewardship.

Please visit the pilot beta version of the OGS web application at the following URL:

For additional information or questions please contact OGS at 405-325-1119 or by email at

NOTE – This is a beta release that is subject to potential downtime due to maintenance and/or operational upgrades. Your feedback is welcomed.

OGS hosts technical and core workshop on the STACK Play

Last September, the Oklahoma Geological Survey hosted a workshop focusing on the Sooner Trend Anadarko Basin Canadian and Kingfisher Counties (STACK) Play in Oklahoma. The play was discovered in 2011, and has quickly become one of the hottest resource plays in North America. Despite extensive drilling activity in this play, understanding of the petroleum geology of the area is limited.

The workshop spanned two days, beginning with a day-long technical workshop held at the Moore-Norman Technology Center, which was attended by over 200 people. The following day, two half-day workshops focusing on core were held at the OGS’s Oklahoma Petroleum Information Center (OPIC) in Norman. Each core workshop was attended by around 40 people.

The main objective of the technical workshop was to learn from researchers and operators in the STACK Play, with an emphasis on the Meramec Lime and Woodford Shale. The core workshops presented core from several key wells of the Meramec and Woodford Shale in Blaine, Kingfisher, and Canadian Counties.

David Brown, OGS Associate Director, said that the OGS was uniquely suited for hosting this workshop.

“It’s one of the most important plays in the country right now,” Brown said, “and it happens to be in our backyard.”

To read more about the STACK Play workshop, see the most recent issue of the Oklahoma Geology Notes.

OGS Hosts Seismology Workshop for Teachers

Eleven educators participated in a two-day workshop hosted by the Oklahoma Geological Survey. The educators are part of a project called BLOSSM in Oklahoma. BLOSSM (Bridging Local Outreach & Seismic Signal Monitoring) aims to place a total of 100 personal seismographs (Raspberry Shakes) into educational institutions in Oklahoma, including schools, libraries, and museums. During the first day of the two-day workshop, teachers and librarians received a Raspberry Shake, learned how to install it in their educational facility, and experimented with the type of data it collects. During the second day of the workshop, participants explored introductory seismology and Earth science concepts with the help of State Seismologist, Dr. Jake Walter, his undergraduate student, Sarah Sundberg, and Education & Outreach Coordinator, Dr. Molly Yunker. Participants concluded the workshop with numerous resources including lesson plans, ideas for classroom activities, a working seismograph, seismology posters, and other teaching tools to aid in STEM education next fall and beyond.

USGS Forecast for Damage from natural and Induced Seismicity for 2018

The U.S. Geological Survey has released updated maps identifying potential ground-shaking hazards.  The report shows continuing elevated risk of damage in Oklahoma, with some expansion of the area of greatest concern.  The expanded area is in part due to slight increases in seismicity in areas that have experienced very few earthquakes previously.  The results are significantly dependent upon algorithms used to distinguish main events from aftershocks, which may be different for induced than for natural earthquakes.  Earthquake frequency has declined by more than three quarters from the peak in 2015-2016.  The Oklahoma Geological Survey, the Oklahoma Corporation Commission, industry and university scientists, are collaborating together to further reduce seismic activity in Oklahoma.
