Estimation of Amplification Spectra for P and SV Waves

In order to evaluate site effects on strong ground motions, the earthquake motions obtained from the vertical array deploying toward the depth of 400m and a part of the satellite array around its array are used. Dividing horizontal and vertical Lime histories into two potions which have primary and secondary arrivals respectively, their amplification spectral ratios between particular two points in and around the vertical array are examined as a problem of incident P- and SV-wave into stratified structures

Measuring the Neutrino Cross Section Using 8 years of Upgoing Muon Neutrinos Observed with IceCube

The IceCube Neutrino Observatory detects neutrinos at energies orders of magnitude higher than those available to current accelerators. Above 40 TeV, neutrinos traveling through the Earth will be absorbed as they interact via charged current interactions with nuclei, creating a deficit of Earth-crossing neutrinos detected at IceCube. The previous published results showed the cross section to be consistent with Standard Model predictions for 1 year of IceCube data. We present a new analysis that uses 8 years of IceCube data to fit the ν$_{μ}$ absorption in the Earth, with statistics an order of magnitude better than previous analyses, and with an improved treatment of systematic uncertainties. It will measure the cross section in three energy bins that span the range 1 TeV to 100 PeV. We will present Monte Carlo studies that demonstrate its sensitivity
