| Abstract |
We present a method of robust inversion (also called IRLS: Iterative Reweighted Least Squares) which is surprisingly insensitive to outlier data points, as it discards automatically the aberrant points, without the necessity for careful human inspection and control of data quality. Different criteria based on residuals and signal-to-noise ratio are injected into the covariance matrix (acting like a weighting function), to perform the robust inversion using the iterative generalized discrete inverse method of Tarantola-Valette. From a practical point of view, this algorithm is used as the Preliminary Determination of Focal Mechanism (PDFM) method, which is a project for rapid estimation of source parameters of strong earthquakes in the context of tsunami warning. The input data to be inverted are spectra of long period surface waves, and as an output, the computed result is the seismic moment tensor, from which focal geometry of an earthquake, and principal stress axes are obtained. This method can be applied to any other method of non-linear (iterative) inversions confronted to the problem of outlier points polluting the data sets.

| Abstract |
We quantify, analyze, and characterize the frequency-dependent microseismic noise recorded by worldwide distributed seismic stations. Microseismic noise is generated through the interaction of ocean waves. It is the strongest ambient noise, and it is observed everywhere on Earth. We introduce a new approach which permits us to detect polarized signals in the time-frequency domain and which we use to characterize the microseismic noise. We analyze 7 years of continuous seismograms from the global GEOSCOPE network. Microseisms are dominated by Rayleigh waves, and we therefore focus on elliptically polarized signals. The polarized signals are detected in the time-frequency domain through a degree of polarization measure. We design polarization spectra and show that microseismic noise is more strongly polarized than noise in other frequency bands. This property is used to measure the directions of the polarized noise at individual stations as a function of time and frequency. Seasonal variations are found for the back azimuths and for the number of polarized signals at many stations. We show that the back azimuth directions are robust measurements that point toward the source areas computed from ocean wave models.
