TL;DR: In this paper, a database of whole Japanese strong ground motion records between 1963 and 2003 is established in order to identify a new standard attenuation relation for Japan, for response acceleration as well as peak value.
Abstract: Following the 1995 Hyogo-ken Nanbu Kobe. Earthquake, the Japanese government, in an effort to prevent future earthquake disasters, installed networks consisting of a large number of strong-motion observation stations. Further, national seismic hazard maps were made available to the public on an Internet website in March 2005 by the Headquarters for Earthquake Research Promotion. However, these maps indicate only the local seismic intensity for Japan, as empirically con- verted from predicted peak velocity in consolidated soils. For various applications, other strong-motion indexes such as the response spectral acceleration are required. In this study, a database of whole Japanese strong ground motion records between 1963 and 2003 is established in order to identify a new standard attenuation relation for Japan, for response acceleration as well as peak value. It is usually very difficult to determine a suitable model form due to the large variability of strong-motion data and correlation among the model variables, because the strong coupling of variables in an attenuation model, and the statistical power of the data is often not large enough to determine the necessity of these parameters. Therefore, in this study, our model has only three variables: earthquake magnitude, shortest distance to the seismic fault plane, and focal depth. To improve predictions given by the model, site correction terms are adopted and additional terms for correcting regional anomalous seismic intensity with respect to the base model are determined. The good fit between the model and observed strong-motion records suggests that the new model is reasonably robust.

TL;DR: In this paper, the authors investigated the responses of two types of soft basins for incident SH, SV, P, and Rayleigh waves in a 2D elastic half-space with special reference to the long duration of strong motions observed in Mexico City during the Michoacan, Mexico, earthquake of 1985.
Abstract: The responses of two types of soft basins for incident SH, SV, P , and Rayleigh waves in a 2-D elastic half-space are investigated with special reference to the long duration of strong motions observed in Mexico City during the Michoacan, Mexico, earthquake of 1985. First, the difficulty for simple 1-D models to reproduce the later part of the accelerogram observed in Mexico City is shown. Then the effect of a 2-D deep basin structure of a relatively large scale (10 km wide and 1 km deep) and a moderate impedance ratio (2.5) is studied. The results show that surface waves generated at the edges of the basin are clearly propagating inside the basin back and forth. However, the increase in duration by these surface waves is 20 sec at most. Introducing another much softer layer inside the basin, we found that the calculated durations and envelop shapes become very similar to the observed ones because of the slowness of surface-wave propagation. These theoretical studies suggest that the exceptionally long duration observed in Mexico City might be caused by a strong, constructive interaction of soft-surface layers with a deep basin structure beneath the city.

TL;DR: In this article, heat flux at the air/ground interface was observed and analyzed for various pavement materials on summer days, and the surface temperature, heat storage and its subsequent emission to the atmosphere were significantly greater for asphalt than for concrete or bare soil.
