The past century has witnessed the emergence of expressive musical forms that originate in appropriated technologies and practices. In most cases, this appropriation is performed without protest— but not always. Carefully negotiating a space for sound as an objective, scientific medium, the field of sonification has cautiously guarded the term from subjective and affective endeavors. This paper...

Hiroyuki HAMAGUCHI, Kazuhiko GOTO, and Ziro SUZUKI Geophysical Institute, Faculty of Science, Tohoku University, Sendai, Japan (Received December 20, 1983) Recent seismic studies using a high-gain seismograph network have demonstrated the existence of a double-planed seismic zone in the descending plate beneath island arcs such as northeastern Japan, Kurile, and Central Aleutian. Several hypoth...

Measurements of seismic anisotropy constitute a very important tool for examining patterns of flow and mineral properties in the Earth’s mantle. A popular strategy for gaining insight into upper mantle processes is to examine the splitting of SK(K)S phases and interpret them in terms of upper mantle anisotropy and deformation; in such studies, any contribution to splitting from anisotropy in th...

The ocean-bottom currents are believed to be largely responsible for the high noise level in ocean bottom seismograph (OBS) data, particular on horizontal components. Due lack of in-situ experiments and measurements, generation mechanism characteristics current-induced still poorly understood. In this paper, we designed an experiment explore features noise. A sensor module from a typical passiv...

We determined the three-dimensional structure of the crust and upper mantle off the Boso Peninsula, Japan, by analyzing seismograms recorded by ocean-bottom seismometers and land stations between 2011 and 2013. We employed seismic tomography to determine the Pand S-wave velocity structures and earthquake locations simultaneously. The tomographic image shows that the mantle parts of the Pacific ...

SYNOPSIS This paper details an assessment of stemming practices at a South African opencast coal mine and their influence on ground vibration air blast. Quantitative qualitative analysis methods were used for the study. The parameters assessed quantitative analyses included length, material type, blast-hole depth, burden, spacing. Pre-blast data from was analysed to determine deviation between ...

The Yogyakarta earthquake in 2006 caused damage several areas, especially the area of Klaten Regency. As a result, many infrastructures, houses, health facilities and casualties have been damaged. research was conducted with target knowing level earth's hazard by microzoning soil vulnerability areas Bayat District, Klaten, Central Java. This study used microseismic method HVSR (Horizontal to Ve...
