By Mack Burke for The Norman Transcript - NORMAN — Oklahoma’s former lead seismologist has testified he was pressured by officials at the University of Oklahoma to suppress findings linking earthquakes with fracking wastewater disposal. In a deposition taken on Oct. 11, Austin Holland alleges he was reprimanded for publishing a peer-reviewed journal article connecting the two and was pressured to alter his findings by Larry Grillot, former dean of OU’s Mewbourne College of Earth and Energy, and Randy Keller, the former director of the Oklahoma Geological Survey. Holland said his decision to leave OU and the Oklahoma Geologic Survey in 2015 was a direct result of pressure from his employers. “I don't know if ‘angry’ is the right word, but just disappointed … that I'd spent my time working towards something, and I thought I was in my dream job, and then I couldn't be a scientist and do what scientists do, and that's publish with colleagues,” he said. “Well, that’s the point at which I realized that for my scientific credibility, I had to leave the position I was in.” In the deposition, Holland claims that Keller and Grillot influenced or altered wording in his findings or presentations. Holland said he met with Grillot and provided an advance copy of a report he co-authored linking seismicity with wastewater disposal. He said Grillot’s response was “this is unacceptable.”
