11. The two types of seismic body waves are compressional waves ( P-waves ) and shear waves ( S-waves ). 12. Recent models of global body waves used over 10 7 traveltimes to model 10 5 to 10 6 unknowns. 13. The accuracy of QMC depends strongly on the initial guess of many-body wave-functions and the form of the many-body wave -function. 14. Quantum Monte Carlo is a way to directly study the many-body problem and the many-body wave function beyond these approximations. 15. Two scales were developed, one based on surface waves, M _ s, and one on body waves , M _ b. 16. The accuracy of QMC depends strongly on the initial guess of many-body wave -functions and the form of the many-body wave-function. 17. Therefore, the body waves undergo less attenuation and reverberation than seismic waves from shallow earthquakes, resulting in sharp body wave peaks. 18. They usually travel slightly faster than Rayleigh waves, about 90 % of the body wave velocity, and have the largest amplitude. 19. Therefore, the body waves undergo less attenuation and reverberation than seismic waves from shallow earthquakes, resulting in sharp body wave peaks. 20. The shock had a body wave magnitude of 3.5 and a maximum Mercalli intensity of V ( " Moderate " ).
