On this edition of StudioTulsa, a discussion with Ziva Branstetter, the Enterprise Editor at the Tulsa World, where she's also the lead reporter for a three-part series of articles called "Quake Debate." The first of these articles appeared yesterday in that newspaper, and the second is in today's World. As is noted of this series at the Tulsa World website: "Over the past two months, the Tulsa World reviewed hundreds of documents and analyzed data files on Oklahoma earthquakes. The World also interviewed dozens of people impacted by the issue statewide." And so Branstetter joins us to address such questions as: Why are so many earthquakes happening in our state? And why has there been such a dramatic rise in the number of quakes in Oklahoma over the past five or six years? What connections can be made -- with certainty -- about all these quakes and the oil industry and its practices? And what do the political leaders of this state -- as well as its insurance companies, scientists, oil executives, and so forth -- have to say on the matter? Branstetter also has much to report on how the people who are dealing with all these quakes (and, in many cases, thereby incurring serious property damage) actually think and feel about them.
