Oil and natural gas industry representatives met with the state's head seismologist over the past several years because they were "nervous about any dialog" connecting the state's ongoing earthquake swarm and industry activity, according to a series of emails published this week by EnergyWire. The emails describe two meetings between Oklahoma Geological Survey Seismologist Austin Holland and executives of Oklahoma City-based Continental Resources Inc. In one email to a colleague, Holland said in November 2013 he had been "asked to have 'coffee' with" OU President David Boren and Continental CEO Harold Hamm.
