Deep tectonic tremors occur at the downdip extent of seismogenic zone due to fluid processes. Beneath northeastern Kii Peninsula, southwestern Japan, there is an along-dip bimodal distribution tremor. However, no constraint exists on structures controlling that distribution. We extract detailed seismological from multi-band receiver functions and evaluate conditional differences in To achieve h...

The stability of the slurry trench is very important in construction underground diaphragm wall. In current research, local instability mainly investigated after excavation a unit slot completely completed. However, process has received little attention. this paper, located high permeability strata wall investigated. A infiltration experiment was carried out to investigate distribution excess p...

The tectonic condition of Gorontalo, which is located in the north Sulawesi Island has implications for spread geothermal potential. area Gorontalo with largest potential Suwawa area, Bone Bolango Regency. Therefore, this study aims to develop a model lineament extraction from digital elevation and analyze geological structure control based on distribution. This research useful development know...

[1] This paper investigates the vertical airflow driven by fluctuating water table within the lower layer of a coastal two-layered system. The upper layer is unsaturated and semipermeable, while the lower is permeable. An analytical solution of the subsurface air pressure fluctuation is derived on the basis of model simplification assumptions, the reasonability of which was examined by numerica...

the purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. in order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, injection rate, number of nozzle hole...
