Seismic monitoring of geomorphic processes [PDF]

open access: gold, 2014
Abstract. In seismology, the signal is usually analysed for earthquake data, but these represent less than 1% of continuous recording. The remaining data are considered as seismic noise and were for a long time ignored. Over the past decades, the analysis of seismic noise has constantly increased in popularity, and this has led to develop new ...

REVIEW OF «WHY WE CANNOT PREDICT STRONG EARTHQUAKES IN THE EARTH’S CRUST» BY I.L. GUFELD, M.I. MATVEEVA AND O.N. NOVOSELOV

open access: yesГеодинамика и тектонофизика, 2015
In the review, directions of future studies of the seismic process are considered. The priority shall be given to studies of the barrier effect of degassing and research of processes that take place in marginal structures.

Heliogeodynamics and seismicity in Pribaikalie

open access: yesГеодинамика и тектонофизика, 2018
The field of earthquake epicentres of Pribaikalie (Russia) is reconstructed from the data of historical and instrumental monitoring of earthquakes. The analysis shows that seismic events in the study area are distributed irregularly in space and time ...

Deep diffusion models for seismic processing

open access: yesComputers & Geosciences, 2023
Seismic data processing involves techniques to deal with undesired effects that occur during acquisition and pre-processing. These effects mainly comprise coherent artefacts such as multiples, non-coherent signals such as electrical noise, and loss of signal information at the receivers that leads to incomplete traces. In the past years, there has been

Post-seismic relaxation from geodetic and seismic data

open access: yesGeodesy and Geodynamics, 2017
We have examined the aftershock sequence and the post-seismic deformation process of the Parkfield earthquake (2004, M = 6, California, USA) source area using GPS data.

Seismic data processing [PDF]

open access: yesElectronics and Power, 1976
An article in the 27th November 1975 Electronics & Power described aspects of seismic exploration in the North Sea. This article considers the computer processing necessary to convert the field data into the final geophysical cross-section which completes this first phase of the geophysical ...

A Method to Avoid Underestimated Risks in Seismic SUPSA and MUPSA for Nuclear Power Plants Caused by Partitioning Events

open access: yesEnergies, 2021
Seismic probabilistic safety assessment (PSA) models for nuclear power plants (NPPs) have many non-rare events whose failure probabilities are proportional to the seismic ground acceleration.

An Analysis of Meteorological Anomalies in Kamchatka in Connection with the Seismic Process

open access: yesAtmosphere
This study investigates the hypothesis that meteorological anomalies may precede earthquake events. Long-term time series of observations for air temperature, atmospheric pressure and precipitation at a meteorological station in Kamchatka are considered.
