Seismic waves - generated both by natural earthquakes and by man-made sources - have produced an enormous amount of information about the Earth's interior. In classical seismology, the Earth is modeled as a sequence of uniform horizontal layers (or spherical shells) having different elastic properties and one determines these properties from travel times and dispersion of seismic waves. The Earth, however, is not made of horizontally uniform layers, and classic seismic methods can take large-scale inhomogeneities into account. Smaller-scale irregularities, on the other hand, require other...

Sato Haruo has been called one of the most representative writers of the Taisho era (1912-1926), a transitional period following Japan's monumental push toward modernization. Although he never identified himself as a modernist, Sato exhibited what some writers have identified as a characteristic of modernism: a complex net of contradictory impulses that embrace both the revolutionary and the conservative, revealing both an optimistic looking to the future and a pessimistic nostalgia for the past.
