The networking and data transmission mode of the field mobile seismic station involves such matters as richness, real-time and effectiveness of seismic data. In this paper, we propose a networking and data transmission mode with CAN bus and embedded technology. In light of the effectiveness, distance, cost and construction relating to data transmission in the field environment, CAN bus was util...

Hypocenter and focal mechanism of an earthquake can be determined by the analysis of signals, named waveforms, related to the wave field produced and recorded by a seismic network. Assuming that waveform similarity implies the similarity of focal parameters, the analysis of those signals characterized by very similar shapes can be used to give important details about the physical phenomena whic...

Introduction: During the Apollo era, a four station seismic network was deployed upon the nearside of the Moon, and returned the first-ever seismic dataset for another body in the Solar System (Fig. 1). The Apollo passive seismic network consisted of four separate stations, deployed on the Moon by the Apollo 12, 14, 15, and 16 astronauts from 1969 to 1972, and remained in continuous operation u...

Today, the major challenge in reservoir characterization is integrating data coming from different sources in varying scales, in order to obtain an accurate and high-resolution reservoir model. The role of seismic data in this integration is often limited to providing a structural model for the reservoir. Its relatively low resolution usually limits its further use. However, its areal coverage ...

This paper investigates the potential application of artificial neural networks in permanent deformation parameter identification for rockfill dams. Two kinds of neural network models, multilayer feedforward network BP and radial basis function RBF networks, are adopted to identify the parameters of seismic permanent deformation for Zipingpu Dam in China. The dynamic analysis is carried out by ...

The recent evolution of induced seismicity in Central United States calls for exhaustive catalogs to improve seismic hazard assessment. Over the last decades, the volume of seismic data has increased exponentially, creating a need for efficient algorithms to reliably detect and locate earthquakes. Today's most elaborate methods scan through the plethora of continuous seismic records, searching ...

Deception Island is an active volcano located in the south Shetland Islands, Antarctica. It constitutes a natural laboratory to test geophysical instruments in extreme conditions, since they have to endure not only the Antarctic climate but also the volcanic environment. Deception is one of the most visited places in Antarctica, both by scientists and tourists, which emphasize the importance of...

This paper presents a framework for seismic vulnerability assessment based on Bayesian Networks. This framework incorporates the HAZUS model, the demand model and the capacity model, which are used to calculate the probabilities of earthquake-induced bridge damage. The framework is here applied to ‘twin’ bridges that are correlated with the demand model and the capacity model. The paper investi...
