      TremorNonlinear Site ResponseResearch:My current work is examining earthquakes

      that are potentially related to human activities, with a specific focus on earthquakes

      and their relationship to wastewater disposal activities associated with oil

      and gas production.I am currently analyzing the recent increase in seismicity

      seen in southern Kansas. This an area of active oil and gas development known

      as the Mississippi Lime play. The USGS Induced Seismicity Project, with the

      Geological Hazards Science Center, has deployed a network of 14 seismometers

      in the area to monitor seismicity. We are actively collaborating with scientists

      and regulators at the Kansas Geological Survey, the Kansas Corporation Commission,

      the Kansas Department of Health and Environment, and the Oklahoma Geological

      Survey to understand these earthquakes.I am also involved in a larger effort

      to compute the earthquake hazard related to induced and potentially induced

      earthquakes. Computing the hazard from induced earthquakes is a new challenge

      for earthquake scientists because they behave differently than natural earthquakes.

      To compute the hazard from these earthquakes requires methods that can handle

      rapid changes in earthquake rates and seismically active regions. We have developed

      preliminary methods that address these new complexities, which estimate the

      hazard over shorter time periods and use very recent earthquake data to predict

      future earthquake behavior. It is probable that having additional industrial

       information that shows the changing operational parameters and expansion and

       contraction of oil and gas fields would help us more accurately describe the

       hazard from induced seismicity. For more information on computing the hazard
