P-waves from cross-correlation of seismic noise
[1] We present results from the cross-correlations of seismic noise recordings among pairs of stations in the Parkfield network, California. When performed on many station pairs at short ranges, the noise correlation function (NCF) is the passive analog to a shot gather made with active sources. We demonstrate the presence of both a P-wave and a Rayleigh wave in the NCF. A time-frequency analys...

متن کاملLocal-scale cross-correlation of seismic noise from the Calico fault experiment
Most studies of seismic noise cross-correlation (NCC) have focused on regional/continental scale imaging using empirical surface-wave Green’s functions extracted from primary (0.05–0.08 Hz) and secondary (0.1–0.16 Hz) microseisms. In this work, we present the NCC results at higher frequencies ([0.5 Hz) from 6 months seismic noise recorded by a local array (*4 km aperture) deployed along the Cal...
متن کامل32 An Automated Despiking Algorithm for Seismic Normal Mode Data
The normal modes spectra of the Earth’s free oscillations contain valuable information on the longest wavelength three dimensional structure of the Earth’s interior. Dahlen (1982) first showed that the optimum record length for measuring eigenfrequencies and decay rates of normal modes using a Hanning taper is 1.1 Q cycles. Since typical modal Q values lie in the range 10 of to 10, optimum wind...
متن کاملObtaining a Unique Solution for the Cross Efficiency by Using the Lexicographic method
Cross efficiency is a method with the idea of peer evaluation instead of self-evaluation, and is used for evaluation and ranking Decision Making Units (DMUs) in Data Envelopment Analysis (DEA). Unlike most existing DEA ranking models which can only rank a subset of DMUs, for example non-efficient or extreme efficient DMUs, cross efficiency can rank all DMUs, even non-extreme ones. However, sinc...
