Estimation of the gas hydrate saturation from multichannel seismic data on the western continental margin of the Chukchi Rise in the Arctic Ocean

open access: yesFrontiers in Earth Science, 2022
A multichannel seismic survey was conducted to investigate the geophysical characteristics of gas hydrates along the western continental margin of the Chukchi Rise around an ARAON mound cluster, which was first recovered in 2016. In the seismic data, gas

Noise generation in the solid Earth, oceans, and atmosphere, from non-linear interacting surface gravity waves in finite depth [PDF]

open access: yes, 2012
Oceanic pressure measurements, even in very deep water, and atmospheric pressure or seismic records, from anywhere on Earth, contain noise with dominant periods between 3 and 10 seconds, that is believed to be excited by ocean surface gravity waves. Most

Interferometric surface-wave isolation and removal [PDF]

open access: yes, 2007
The removal of surface waves (ground roll) from land seismic data is critical in seismic processing because these waves tend to mask informative body-wave arrivals.

A near-surface seismic scattered wave separation method

open access: yesPetroleum Exploration and Development, 2014
Considering that near-surface scattered waves could not be suppressed by conventional denoise method, this paper analyzes the characteristics of scattered waves and achieves the near-surface scattered wave separation by the seismic interferometry theory.

Numerical analysis of seismic wave amplification in Nice (France) and comparisons with experiments [PDF]

open access: yes, 2000
The analysis of site effects is very important since the amplification of seismic motion in some specific areas can be very strong. In this paper, the site considered is located in the centre of Nice on the French Riviera.

High temperature elastic anisotropy of the perovskite and post-perovskite polymorphs of Al2O3 [PDF]

open access: yes, 2005
Finite temperature ab initio molecular dynamics calculations were performed to determine the high temperature elastic and seismic properties of the perovskite and post-perovskite phases of pure end-member Al2O3.

Determination of the structure of the earth's crust by changing the velocity of seismic waves from the earthquake data

open access: yesВестник Дагестанского государственного технического университета: Технические науки, 2021
Objective. A study of the structure of the earth's crust by determining the velocities of seismic waves from previously broken sections of the earth's crust.Methods. Two mathematical methods are proposed for determining the seismic wave velocities.

Seismic waves increase permeability [PDF]

open access: yesNature, 2006
Earthquakes have been observed to affect hydrological systems in a variety of ways--water well levels can change dramatically, streams can become fuller and spring discharges can increase at the time of earthquakes. Distant earthquakes may even increase the permeability in faults. Most of these hydrological observations can be explained by some form of

Energy Characteristics of Seismic Waves on Cardox Blasting Tube

open access: yesGeofluids, 2021
In order to study the energy characteristics of seismic waves on the liquid CO2 blasting system, the blasting seismic wave signal of liquid CO2 blasting was obtained by on-site microseismic monitoring tests.
