Seismic Signature of Rain and Wind Inferred From Seismic Data

چکیده
Seismic stations are increasingly used to monitor river activity and quantify sediment transport during flood events. In tropical regions, cyclone-induced floods often associated with heavy rain strong wind episodes, generating complex seismic records involving the simultaneous signature of water, sediment, rainfall wind. Hence, characterization is then required better decipher each process improve our understanding signature. this study, we investigate experimentally response using data recorded by geophones deployed in various soil types at different burial depth (BD), co-located meteorological instruments. Our results show that power spectral density (PSD) noise intensifies a frequency between 60 500 Hz for 5 wind, presence precipitation as low 0.025 mm/min and/or speed ≥3 m/s. PSD analysis indicates signal decreases BD value ∼2–5 dB difference 10 cm. We also observe type has its own The 4-min root mean square correlation amplitude suggests they best correlate Pearson coefficient >0.90 30 transfer function rate (or kinetic energy) shows geophone can be robust proxy these parameters.

Extracting Seismic Profiles from Background Seismic Signals
The idea of obtaining the seismic trace representing the impulse response at one receiver due to a source at another receiver has discussed by many authors. Jon Claerbout (see e.g. Rickett and Claerbout, 1996; Claerbout, web) introduced the concept to seismology. It has been investigated in the laboratory by Lobkis and Weaver (2001), observed in seismic data by Campillio and Paul (2003), and in...
متن کاملMigration of Seismic Data
Prospecting for oil and gas resources poses the problem of determining the geological structure of the earth's crust from indirect measurements. Seismic migration is an acoustic image reconstruction technique based on the inversion of the scalar wave equation. Extensive computation is necessary before reliable information can be extracted from large sets of recorded data. In this article, a col...
متن کاملMechanical System Simulations for Seismic Signature Modeling
In this paper we present seismic signature simulations using ground vibration inputs from highfidelity 3-D mechanical system models. Results for an M1A1 and T72 are discussed. By analyzing the simulated seismic signature data in conjunction with the spectral features associated with the vibrations of specific vehicle sprung and un-sprung components we are able to make unambiguous associations o...
متن کاملImproved seismic fragility modeling from empirical data
The improved empirical fragility model addresses statistical dependence among observations of seismic performances, which arises from common but unknown factors influencing the observations. The proposed model accounts for this dependence by explicitly including common variables in the formulation of the limit state for individual components. Additionally, the fact that observations of the same...
متن کاملCharacterising Seismic Data
When a seismologist analyses a new seismogram it is often useful to have access to a set of similar seismograms. For example if she tries to determine the event, if any, that caused the particular readings on her seismogram. So, the question is: when are two seismograms similar? To define such a notion of similarity, we first preprocess the seismogram by a wavelet decomposition, followed by a d...
