Determining Soft Layer Thickness Using Ambient Seismic Noise Record Analysis in Kota Baru, South Lampung

Makara Journal of Science, 2019
The local site effect of an earthquake can be calculated through an analysis of short period ambient noise, known as microtremors. The fundamental frequency and amplification factors can be identified by analyzing microtremors using the Horizontal to ...

A HVSR inversion method based on the multi-modal forest optimization algorithm

Journal of Physics: Conference Series
Abstract The exploration of urban underground spaces is of great significance to urban planning, geological disaster prevention, resource exploration, and environmental monitoring. However, due to severe interferences, conventional seismic methods cannot adapt to the complex urban environment well.

On higher order estimates in quantum electrodynamics [PDF]

, 2009
We propose a new method to derive certain higher order estimates in quantum electrodynamics. Our method is particularly convenient in the application to the non-local semi-relativistic models of quantum electrodynamics as it avoids the use of iterated ...

Rapid Estimation of Vs30 Through Elitist Genetic Algorithm HVSR Inversion and Refraction Microtremor Data Analysis in the Greater Metro Manila Area and Leyte Province, Philippines

Applied Sciences
Vs30, the average shear wave velocity in the uppermost 30 m, is a critical parameter in seismic hazard analysis. In the Philippines, the Refraction Microtremor (ReMi) survey is the standard method for Vs30 Estimation.

Seismic site characterization at the western Cephalonia Island in the aftermath of the 2014 earthquake series

International Journal of Geo-Engineering, 2017
Background The site response during a strong earthquake event may be proven crucial for earthquake hazard assessment and risk mitigation. Two moderate magnitude earthquakes that occurred in early 2014 in Cephalonia produced the largest ground motion ...
