S-wave velocity structure beneath the Mátra Mountains (Hungary) inferred from teleseismic receiver functions

The crustal and uppermost mantle structure beneath the Matra Mountains has been investigated by means of the inversion of teleseismic P-wave receiver functions. Earthquakes recorded at the PSZ station in the period 1995–2000 with epicentral distances of between 20° and 100° and with magnitudes greater than 5.5 have been selected for analysis if their signal-to-noise ratio was sufficiently high. Source equalisation has been carried out to gain the radial and tangential receiver functions. The traces from similar backazimuths and distances were stacked to improve the data quality.
