CFM: a Convolutional network for First Motion polarity classification of earthquake waveforms.
2023The knowledge of the crustal stress field is essential in the evaluation of the seismic hazard of an area.To this aim, it is necessary to derive reliable focal mechanisms mainly when small earthquakes have to be included in the computation. The first motion focal mechanism solution techniques are still widely used in modern softwares. The determination

A method for automatically determining first-motion polarities is developed, with a view to its application to the focal mechanism analysis of massive microseismic events caused by hydraulic fracturing. The method is based on two assumptions: the existence of a point source, which has negligible effects of fault finiteness and rupture directivity; and ...

The International Seismological Centre (ISC) routinely calculates and makes available automatic earthquake focal mechanisms by combining reported parametric data (first-motion polarities) available in the reviewed ISC Bulletin and auto-picked first-motion polarities obtained from waveform data using a broadband automatic picker.

Moment tensor determinations of small earthquakes are quite challenging. It is because their signal‐to‐noise ratio is satisfactory only at frequencies above the microseismic noise peak (∼0.2 Hz), and waveforms can be modeled only up to ∼1–2 Hz at relatively near stations (epicentral distance of a few kilometers).
