Geophysics and Tilt-Sensing
Dr. Mark Zumberge is a Research Geophysicist at the University of California, San Diego. His PhD is in physics (Univ. of Colorado) and he has spent nearly 40 years developing instrumentation to detect crustal deformation associated with earthquakes, volcanos, and sub-surface fluid movement caused both by natural gas production and CO2 sequestration. He developed a seafloor gravity surveying method that has been used on a half-dozen North Sea production fields and also has several patents on optical methods to monitor strain, tilt, and gravity changes. In addition to his position at the university, he is president of the small consulting firm Newberry Williams, Inc.
