Elastic stress field of the Earth and earthquake focal mechanisms. ![]() Problematic non-double-couple mechanism of the 2002 Amfilochia Mw5 earthquake, Western Greece. The dynamic parameters of the sources of 4 earthquakes occurred in 2012-2013 are retrieved by using data from the spectra of records converted into displacements according to the Brune model.Īdamova P., Sokos E., Zahradnik J., 2009. The similarity of the focal mechanisms for repeated earthquakes is shown. The focal mechanisms and types of faults are determined by using this method for 6 events occurred in the Transcarpathian region. A sequence of plotting diagrams for determining the focal mechanism is presented. This method is based on identifying the best location option of nodal planes relatively to both the fuzzy P-wave arrivals and the values of the logarithm of the ratio of the S-wave amplitude to the P-wave amplitude. ![]() On the example of several events occurred in the Carpathian region of Ukraine, the solving of this problem with a graphic method is proposed. Subbotin Institute of Geophysics of the National Academy of Sciences of Ukraine, Lviv, UkraineĮarthquake source, graphic method, seismic wave, anisotropic medium Abstract One of the urgent problems - a solution of the focal mechanism of an earthquake is considered. An acknowledgment of accessibility through the ISC repository would be appropriate. Currently, these are no longer easily accessible to the public.
