Frequency and Amplification for Assessing site Effects and PVS in the Padang City Railway
JIF (Jurnal Ilmu Fisika), 2023 The train uses a special line in the form of railroad tracks that produce vibrations during movement. This study aims to determine the type of soil layer and the peak particle velocity due to the train around the Padang City train line.

Valley of Mexico site response from non‐reference site approach
Earthquake Spectra, Volume 41, Issue 2, Page 1029-1059, May 2025.We present a model for Valley of Mexico site response that is referenced to a 30 m time‐averaged shear wave velocity (VS30) of 760 m/s. This reference condition ensures compatibility with regional ground motion models (GMM) for Central America and Mexico (CAM), which were developed from an expanded version of the NGA‐Subduction (NGA‐Sub) database as ...

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2021 Watukumpul is an area that is prone to landslides, so determining the soft layer thickness is very important to identify the landslide potential. The soft layer thickness can be estimated using microtremor signal measurements which analyzed using the ...

Effects of Surface Geology on Seismic Ground Motion Deduced from Ambient-Noise Measurements in the Town of Avellino, Irpinia Region (Italy) [PDF]
, 2011 The effects of surface geology on ground motion provide an important tool in seismic hazard studies. It is well known that the presence of soft sediments can cause amplification of the ground motion at the surface, particularly when there is a sharp ...

Comparative Study of Microtremor Analysis Methods
Pure and Applied Geophysics, 2001 During a multidisciplinary microzonation pilot project in the city of Heraklion (Crete, Greece), microtremor data were collected at the top of exploratory boreholes specifically designed for the purposes of the project, over a period of 5 days, for 4 h/day at 125 Hz (continuous recordings).

Softening and Recovery of Near‐Surface Layers During the 2024 M7.6 Noto Earthquake
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.Abstract On 1 January 2024, a devastating MJ 7.6 earthquake occurred on the Noto Peninsula in Japan. When such a strong earthquake occurs, affected near‐surface soil layers behave nonlinearly and may undergo some structural changes driven by Flow Liquefaction, Cyclic Mobility, or Slow Dynamics phenomena.

Comparison of earthquake and microtremor ground motions in El Centro, California [PDF]
, 1973 Strong earthquake ground shaking has been investigated by the study of 15 events recorded in El Centro, California. The strong-motion records analyzed show that no simple features (e.g., local site conditions) govern the details of local ground shaking ...

Integration of HVSR measures and stratigraphic constraints for seismic microzonation studies: the case of Oliveri (ME) [PDF]
, 2014 Because of its high seismic hazard the urban area of Oliveri has been subject of first level seismic microzonation. The town develops on a large coastal plain made of mixed fluvial/marine sediments, overlapping a complexly deformed substrate. In order to

Ocular microtremor measurement using laser-speckle metrology [PDF]
Journal of Biomedical Optics, 2013 We describe a novel, noninvasive measurement approach for recording a small involuntary tremor of the eye known as ocular microtremor. The method is based on measuring out-of-plane angular displacements of a target by using laser-speckle correlation of images recorded in the Fourier plane of a lens.
