Leland Timothy LongLeland Timothy Long is Emeritus Professor of Geophysics at Georgia Institute of Technology, where he has taught geophysics for over 40 years, on topics including exploration geophysics, potential theory, seismology, data analysis and earth science. H is also a licensed Professional Geologist in Georgia and consults on topics of gravity data interpretation, seismic hazard and blast vibration. Professor Long's research interests in potential methods include the interpretation of regional crustal structures for seismic hazards, deflections of the vertical, statistical properties of gravity field, and microgravity for the detection of sink holes, and his research interests in seismology have emphasized seismicity, seismic networks, induced seismology, many aspects of theoretical seismology related to scattering and scattering inversion, and near-surface surface wave analysis. In 2006, Professor Long was awarded the Jesuit Seismological Association Award honouring outstanding contributions to observational seismology. Read More Read Less
