Our Objectives

The Geologic Maps Foundation (GMF) was founded in 2016 with the following objectives:

  • Provide public education on geologic maps that includes the uses and benefits of these vital data sets and interpretations, plus teaching map reading and map making skills. Educational opportunities are provided through geo-hikes (for hikers and geologists), professional geologic field trips, and courses. These events are listed and open for RSVPs at: https://www.meetup.com/Geo-hikes/
  • Preservation of unpublished and out-of-print geologic maps, cross sections, and other geologic data and interpretations, and make available to the public, researchers, and policy makers via GMF’s web page: see Samples & Library pull down menu at: http://geologicmapsfoundation.org/.
  • Provide the public immediate education and information on potential geologic hazards. For instance, using a social media campaign, GMF provided the public in Ventura and Santa Barbara Counties a Debris Flow Facts & Safety pamphlet immediately following the 2017 Thomas Fire in western Ventura and eastern Santa Barbara Counties, and immediately following the 2018 fires in eastern Ventura County: bottom page link at: http://geologicmapsfoundation.org/ Or: Click to see our 2017-2018 efforts.
  • Perform geologic research that deals with the world’s changing energy challenges and associated environmental questions; for example, a present focus is the siting of natural gas storage fields across active faults in California: http://geologicmapsfoundation.org/publications.html And Click to see our 2017-2018 efforts.

Current Focus

Avoiding massive methane leaks from natural gas storage fields: The concealed earthquake faulting hazard to the Aliso Canyon and other gas storage fields in the US

In the US over 400 underground natural gas (methane) storage fields supply nearly one-third of our nation’s energy needs, and that share is expected to grow in response to low carbon use requirements and ample domestic supplies. Given this substantial energy role how safe is gas storage in seismically prone areas where earthquake fault movements can shear wells? Gas fields with many active fault crossings have the potential to suddenly release massive amounts of methane. For instance, at the Aliso Canyon Gas Storage field (ACGSF) all 114 gas wells cross the Santa Susana fault (SSF) to reach the deeper gas reservoir. Seismologists and geologists have evidence that the SSF is earthquake active with a high rate of fault movement during the most recent period of geologic time. They characterize the SSF as capable of producing moderate to large earthquakes with fault movements sufficient to create breaks and leaks in high pressure wells. The recent ACGSF leak, although probably not due to fault movement, showed the difficult and lengthy process to regain control of a subsurface leak in a gas well and its significant regional and local impacts. In the four month long struggle to control the SS-25 well it released 20% of California’s annual methane emission (CARB, 2016). ~8,000 residents were relocated and two public schools closed (Harris and Walker, 2016). The operator, the Southern California Gas Company (a Sempra owned company), has to date spent $700+ MM on this event. The ACGSF leak was stopped by drilling a relief well that took over two months, and the event showed the lengthy and costly effort required to stop an underground leak from one well in a pressured and large volume storage field. Furthermore, methane, a much more effective heat-trapping gas than carbon dioxide, released to the atmosphere in large amounts can negate a good portion of the nation’s carbon dioxide reduction efforts (IPCC, 2014). In the event of a massive methane leak involving numerous wells regaining control and mitigation would be costly, perhaps impossible, and would have enormous safety, societal, and environmental consequences. As many of the storage field operators are public utilities it is possible that both the rate payers and tax payers could end up with these burdens. The earthquake fault hazard and its potential impact to the environment, the nation’s energy supply, and nearby communities have been nearly unrecognized by the gas storage industry, and consequently by policymakers. The nation, and especially communities adjacent to the storage fields, which are lacking the ability to retain independent technical expertise, must rely on the transparency and technical conclusions of the operators. Likewise, the regulator’s judgment relies heavily on the operator’s technical conclusions and thoroughness. To date, the Geologic Maps Foundation (GMF) is the only independent scientific nonprofit focused on this substantial environmental and safety hazard (Davis, 2016 a, b, and c). GMF’s evaluation should continue into 2017 in order to influence new gas well regulations being proposed by industry advisory, state, and federal agencies during the next two years. Concurrently, it is critical to inform and educate the public, their elected officials, and national and local organizations concerned with safe and clean energy. GMF is seeking funding to continue its efforts.
