OGS Statement on February 5, 2021 earthquakes near Perry

Around 10:17 AM, local time, on February 5, 2021, a M3.5 and M3.7 earthquake occurred less than a minute apart from one another between the towns of Lucien, OK and Covington, OK. Subsequently, a M4.2 earthquake occurred around 11:49 AM, with reports of strong shaking in the immediate area and light shaking in Tulsa, Oklahoma City, Norman, and Wichita, KS. The M4.2 earthquake was preceded by activity in the last several years, with most previous earthquakes too small to be felt by people. At least 8 aftershocks have been recorded as of this update and there remains a high likelihood of more aftershocks for the next several days. Whereas most aftershocks are smaller than the mainshock, a very small fraction of aftershocks result in a larger earthquake than the main event. The seismic hazard remains high in the area. We will continue to monitor the seismicity and provide assistance to the Oklahoma Corporation Commission (OCC), other state agencies, and the public. The earthquake catalog is updated in real-time and the state catalog is redundantly reported to USGS; USGS events within the state are derived directly from OGS earthquake locations and magnitudes since May 2019.

The Oklahoma Geological Survey (OGS) is a state agency and a research organization of the University of Oklahoma. OGS monitors seismicity throughout the state; an effort that began with the Leonard Geophysical Observatory starting in the 1970s and continues today in Norman. Today, the seismic network encompasses 100+ seismometers that deliver real-time data to the central data hub in Norman. Analysts in Norman process the seismic data and deliver updated earthquake locations, magnitudes, and other scientific data products that are freely-available and shared through the OGS website and through collaborative partners.

Oklahoma Geological Survey Announces New Director

Nicholas Hayman, an accomplished researcher whose area of expertise centers around marine geology and geophysics, tectonics, seismicity and the interdependence between engineering and geosciences, recently was named as director of the Oklahoma Geological Survey at the University of Oklahoma. Hayman comes from the Institute for Geophysics at the University of Texas and succeeds former director Jerry Boak, who retired in 2019.

Hayman hopes his new role will produce increased collaboration between the survey and public and private entities throughout Oklahoma.

“We’re going to chart new directions in geological and energy sciences,” said Hayman. “By developing external support and broader collaboration with researchers around the state, I want to continue the work on both understanding and mitigating induced seismicity in Oklahoma, while also broadening our scope to study the local effectiveness of new technologies in upcoming areas such as carbon capture and alternative energy resources. Most importantly, we will maintain the survey’s core mission of serving Oklahomans by providing an enhanced understanding of their environment.”

Hayman earned his doctorate at the University of Washington in 2003.

“We are so excited to have found someone so qualified to lead the Oklahoma Geological Survey,” said Mike Stice, dean of the Mewbourne College of Earth and Energy. “Nick Hayman is a proven leader and is already a well-known researcher. We look forward to his leadership as the survey continues to provide excellence in service to the university, the state and the public at large.”

OGS Statement on June 20, 2020 earthquake near Perry

Updated 9:00am

At 10:15 PM, local time, on June 20, 2020 a Magnitude 4.2 earthquake occurred northwest of Perry, OK, with reports of strong shaking in the immediate area and light shaking in Tulsa, Oklahoma City, Norman, and Wichita. The M4.2 earthquake was preceded by activity in the last several months, with most previous earthquakes too small to be felt by people. Several aftershocks have been recorded over the last several days and there remains a high likelihood of more aftershocks for the next several days. Whereas most aftershocks are smaller than the mainshock, a very small fraction of aftershocks result in a larger earthquake than the main event. The seismic hazard remains high in the area. We will continue to monitor the seismicity and provide assistance to the Oklahoma Corporation Commission (OCC), other state agencies, and the public.

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:

The Acoustic Anomaly Mystery

Recently, the OGS Seismic Team noticed an unusual acoustic pattern recorded by the seismic network. Read about 'The Anomaly' on the Field Blog.

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: http://web-pilot.ogs.ou.edu/wells/

For additional information or questions please contact OGS at 405-325-1119 or by email at rdtarver@ou.edu.

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.

Oklahoma researchers’ studies on Pawnee quake focus of peer-reviewed journal

Seismological Research Letters, an internationally recognized peer-reviewed journal, is dedicating a special issue to scientific studies related to the 5.8 magnitude earthquake that struck near Pawnee last September — the largest recorded seismic event in Oklahoma history.

Dr. Kyle Murray Honored with Environmental Stewardship Award

On April 20, 2017, Dr. Kyle E. Murray of the Oklahoma Geological Survey (OGS) was presented a 'Recognition for Environmental Stewardship' Award from the University of Oklahoma Environmental Concerns Committee (http://www.ou.edu/admin/ecc/) in appreciation of his efforts in responsible use and protection of the environment through conservation and sustainable practices. The mission of the Environmental Concerns Committee is to 'advise the president of the university concerning environmental issues and to promote awareness of energy and other resources conservation, recycling, and personal and environmental well-being and safety.'
