The study of rock and soil strength is one the roles geophysics. This uses microtremor method to determine shear velocity at a depth 30 meters (Vs30) ground strain (GSS) which will show under force. was investigated in Pindul Cave Area. samples consisted karst types. HVSR analyzed area. results found that GSS map general has range values 3,1x10-1 – 3.0x10-2, with phenomenon land subsidence elas...

The City of David constitutes one the most important commercial centers Republic Panama. However, it is located on a coastal plane, close to an area with high seismic activity and has been affected by significant earthquakes (18 July 1934, Mw = 7.4 12 March 1962, 6.7). goal this study estimate effects classify soil in David. experimental work entailed measurement environmental noise for H/V spe...

Voice stress analysis (VSA) is accomplished by measuring fluctuations in the physiological microtremor present in speech. In this paper, Empirical Mode Decomposition is compared to traditional Fast Fourier Transform in the analysis of the physiological microtremor. The results are expected to show that EMD is better suited in the detection of stress in voice.

Many landslides occur in Samigaluh District, Kulon Progo Regency, Yogyakarta, Indonesia. However, no research discusses that often on the main road connecting city of Yogyakarta and various tourist resorts Samigaluh. This study aims at determining soil vulnerability lithology model as a contribution to landslide mitigation planning. is based shear wave velocity (Vs) layer thickness derived by m...

According to historical documents and Moroccan earthquakes catalogs, the coastal zone has suffered in past from several earthquakes. Understanding how sedimentary basins respond seismic-wave energy generated by earthquake events is a significant concern for seismic-hazard estimation risk analysis. The main goal of this study determine distribution natural frequency value (F), amplification fact...

Lombok Island is an active seismic area in Indonesia potentially hit by earthquake due to located between two generators from the south and North. Several large earthquakes rocked Lombok, with a magnitude of 6.4 on July 29, 2018, 7.0 August 5, 2018. This study aims determine characteristics local site effect based dominant frequency value ( ), soil amplification sediment layer thickness (d), , ...

The train uses a special line in the form of railroad tracks that produce vibrations during movement. This study aims to determine type soil layer and peak particle velocity due around Padang City line. acquisition was carried out at 8 points with recording duration 65 minutes using three geophone components. Microtremor data analyzed horizontal vertical spectral ratio (HVSR) method. results sh...
