Landslides are the most common geological phenomenon in Indonesia.The event is damage to public infrastructure, and fatalities was a big impact. Therefore, mapping geometry of landslides part mitigation effort possible by geophysical methods. In this research, we applied seismic refraction tomography (SRT) study sliding zone from landslide event.TheNational Disaster Management Authority reporte...

Abstract Several mountainous river basins in Japan do not have a consistent hydrological record due to their complex environment and remoteness, as discharge measurements are economically feasible. However, understanding the flow rate of rivers during extreme events is essential for preventing flood disasters around basins. In this study, we used high-sensitivity seismograph network (Hi-net) id...

The construction of a reservoir on large-thickness collapsible loess cover will significantly increase the occurrence dam break disasters. main reason may be that although gradation particle is not uniform. clay content less than 10%. Piping channels easily form under action force and collapsibility. Near-static liquefaction in body saturated condition lead to piping or loss soil strength. Ther...

The contribution of mantle upwellings varying spatial extent to Cenozoic magmatism across Africa is debated because geochemical and seismological tools used interrogate them are primarily sensitive either composition or temperature. Thermochemical conditions control the depth at which materials undergo phase changes, cause seismic discontinuities. Mapping discontinuities transition zone (MTZ) b...

We conducted synthetic experiments to evaluate the effects of shallow-layer reverberation in oceanic regions on P-wave travel times measured by waveform cross-correlation. Time shift due to waveform distortion by the reverberation was estimated as a function of period. Reverberations in the crystalline crust advance the P-waves by a frequency-independent time shift of about 0.3 s in oceans. Sed...

Soil properties play a crucial role in understanding the mechanisms of erosion and consequently developing appropriate mitigation strategies. The aim this study is to determine elastic parameters soil an erosion-prone area using Multichannel Analysis Surface Wave (MASW) method geophysical exploration. active MASW was adopted for study. Data were acquired 24-channel ABEM Terralock MATK-6 seismog...
