Background, Value and Recent Activities (since 7/1/19)
For the last three years, RISC has helped integrate and communicate research on fluid injection induced seismicity being conducted by state geological surveys and others. An integrated research approach is needed for the southern midcontinent of the United States, given the importance of fossil energy exploration and production in this region to the Nation and local state economies, and given the potential risk of fluid-induced earthquake activity on these activities and the industry. RISC is the only multistate, regional program designed to communicate and broaden geologic knowledge and interpretation on issues in this technical area. State geological surveys have a unique role in conducting applied research and scientific investigations and communicating findings to the public and their respective regulator communities. RISC helps to fill this role.

Over the past three years, RISC has been involved in several activities directly related to communicating and integrating research. Besides the large number of presentations made by RISC members, RISC has also organized a highly successful webinar series that routinely brings ~90-100 connections and 100+ attendees to each presentation. The presenters have been from multiple institutions (see the list below) and have discussed a variety of induced seismicity related topics using a common-language style that can be understood by scientists, regulators, and the general public, all of whom attend. We currently have over 250 people on our email list. All presentations are post-processed into a professional-style format, and posted online with the slide deck available for any visitors to download. All of these activities were developed through discussions with RISC members who felt that new styles of communication, beyond those of traditional talks and journal articles. Were needed. We have received numerous positive comments about the quality of the speakers, their style of communicating, and the importance of the information.

RISC funding for the Oklahoma Geological Survey (OGS) primarily funds opportunities for outreach, in the form of publications aimed at the general public, presentations are scholarly and other public meetings, many with a wide variety of attendees, and peer reviewed journal articles. We have arranged the contributions according to RISC member, and then by type of contribution.

Dr. Ogwari began 20% support under the RISC subaward to OU in mid-2020, and is researching earthquakes with very short recurrence times in Oklahoma, also called double or twin events. These earthquakes appear to most frequently occur near hydraulic fracturing operations. The findings will be useful to the entire RISC group and we will share our findings with the members and general public. Over the last few years, the RISC subaward has supported conference travel to several regional conferences to present to mixed audiences of academic and industry scientists.
- December 2019, AGU Meeting, December 2019, San Francisco, CA, presented poster: Ground motion analysis of hydraulic-fracture triggered earthquakes in Oklahoma
- November 2019, SPE/SEG conference on Induced Seismicity, Dallas, TX, attended and participated in discussions
Arkansas Geological Survey
The Arkansas Geological Survey maintains an earthquake catalog for Arkansas. As of 6/15/2020, Arkansas’ catalog include 23 felt earthquakes. Of particular note is recent seismic activity in the vicinity of El Dorado, Arkansas. A magnitude (M) 2.8 occurred approximately eight miles southeast of El Dorado, AR. This event is in close proximity to a M2.8 that occurred on February 24, 2020. At the present time, there is insufficient data to determine whether this activity was natural or induced. The El Dorado seismic station cell modem went off line just before the event. The AGS has communicated with CERI, who will review the event again and provide the AGS with their confidence level in the location and depth of the earthquake. The El Dorado area has experienced periodic episodes of seismic activity in the past including an estimated M4.0+ in the 1930’s and a M3.0 in 2007. Some activity (EQ cluster in the 1980’s) was linked to SWD injection by Cox (1991). The other earthquakes may or may not have been related to human activity.
On November 6, 2019, the Arkansas Geological Survey hosted a paleoseismology field trip near Marianna, Arkansas. Field trip leaders included Drs. Martitia Tuttle and Haydar Al-Shukri. Approximately 50 participants (university students, emergency management, state geological surveys), from an 8- state area attended the event. The field trip was sponsored by State Farm Insurance, RISC, and the USGS. Two documentaries (in progress) are being prepared, in addition to field manuals, as a part of the deliverables.
Through RISC funding, the Arkansas Geological Survey staff was able to participate in the Groundwater Protection Council Meeting (RISC planning) in San Antonio in February and National Earthquake Conference (breakout session focused on induced seismicity) held in San Diego, CA in March, 2020.
