Charles J. Ammon
My research is focused on the use of seismograms to better image earth structure and earthquake ruptures. My current research projects include the combination of receiver functions, surface-wave dispersion, and gravity observations to improve estimates of lithospheric structure (working with current student Chengping Chai, Monica Maceira, of Los Alamos, and Bob Herrmann of Saint Louis University). I am also working with current PhD student Jonas Kintner, and former Ph.D. student Mike Cleveland (now at Los Alamos National Laboratory) to develop methods to exploit seismic surface waves to improve earthquake locations in remote regions. Finally, I have ongoing work in tomographic imaging of earthquakes and earth structure with researchers from other institutions. (Last updated in August 2015)
