Slow Earthquakes in the Microseism Frequency Band (0.1–1.0 Hz) off Kii Peninsula, Japan

Geophysical Research Letters, 2018
It is difficult to detect the signal of slow deformation in the 0.1–1.0 Hz frequency band between tectonic tremors and very low frequency events, where microseism noise is dominant.

PEER Testbed Study on a Laboratory Building: Exercising Seismic Performance Assessment [PDF]

, 2005
From 2002 to 2004 (years five and six of a ten-year funding cycle), the PEER Center organized the majority of its research around six testbeds. Two buildings and two bridges, a campus, and a transportation network were selected as case studies to ...

From Corporate Social Responsibility to Organizational Resilience: The Role of Sustainability Control Systems and Governance Heterogeneity

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Corporate social responsibility (CSR) has increasingly been recognized as a strategic lever for enhancing organizational resilience. Although CSR literature is abundant, prior research has not fully explained how distinct CSR types, such as altruistic, promotional, and value‐creating, influence organizational resilience through sustainability ...

Fractal analysis for the ULF data during the 1993 Guam earthquake to study prefracture criticality [PDF]

Nonlinear Processes in Geophysics, 2006
An extremely large earthquake (with magnitude of 8.2) happened on 8 August 1993 near the Guam island, and ultra-low-frequency (ULF) (frequency less than 1 Hz) electromagnetic fields were measured by 3-axis induction magnetometers at an observing station (

Anomaly disturbances of the magnetic fields before the strong earthquake in Japan on March 11, 2011

Annals of Geophysics, 2012
<p>One of the strongest earthquakes, with magnitude M 8.9, occurred at the sea bottom near to the east coast of Japan on March 11, 2011. This study is devoted to the investigation of anomaly disturbances in the main magnetic field of the Earth and ...

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

Deep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Simulation of seismic response in a city-like environment

, 2004
We study the seismic response of idealized 2D cities, constituted by non equally-spaced, non equally-sized homogenized blocks anchored in a soft layer overlying a hard half space. The blocks and soft layer are occupied by dissipative media.

Seismicity and Ground Motion Simulations of the SW Iberia Margin [PDF]

, 2010
In this study, we focus on the region between Gorringe Bank and the Horseshoe Fault located in the SW Iberia margin, which is believed to be the site of the great 1755 earthquake.

Study on the failure mechanism of the shield excavation face in the sandy cobble stratum under different buried depths

Deep Underground Science and Engineering, EarlyView.
Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...
