Reverse Time Migration Method for Joint Imaging of Multiples and Primaries in Vertical Seismic Profiling

open access: yesApplied Sciences
Vertical seismic profiling (VSP) has garnered widespread attention because of its ability to provide high-quality seismic data. Owing to the unique characteristics of VSP observation systems, conventional multiple-wave imaging methods designed for ...

The Nikolaevskiy equation with dispersion

open access: yes, 2010
The Nikolaevskiy equation was originally proposed as a model for seismic waves and is also a model for a wide variety of systems incorporating a neutral, Goldstone mode, including electroconvection and reaction-diffusion systems.

Characteristics of T-wave generation around submarine volcanoes

open access: yesEarth, Planets and Space
Unexpected major tsunamis have occurred at Sumisu Caldera with an interval of about 10 years. Recently, a similar unexpected major tsunami from Sofu Seamount was reported. Sumisu Caldera and Sofu Seamount are submarine volcanoes far south of Japan. Large

Critical Distance of the Seismic Waves’ Impact in Disintegration of Rock Blasting

open access: yesShock and Vibration, 2019
The presented paper deals with attenuation of seismic waves, which depends on the degree of disintegration of the rock environment in which seismic waves are propagated due to the explosion of explosive charges during blasting operations. Measurements of

Simulation of underground gravity gradients from stochastic seismic fields

open access: yes, 2009
We present results obtained from a finite-element simulation of seismic displacement fields and of gravity gradients generated by those fields. The displacement field is constructed by a plane wave model with a 3D isotropic stochastic field and a 2D ...

Response spectra and design spectrum of ground fissures site under seismic action

open access: yesScientific Reports
To make efficient use of land resources and minimize the seismic destruction of structures in the ground fissures zone, the shaking table tests and 3-dimensional numerical calculation of the soil were completed, based on the ground fissures site in Xi’an

A Bayesian Framework for Estimating Seismic Wave Arrival Time [PDF]

open access: yes, 2019
Because earthquakes have a large impact on human society, statistical methods for better studying earthquakes are required. One characteristic of earthquakes is the arrival time of seismic waves at a seismic signal sensor.
