Abstract (in english)
   We analyze refraction measurements along a short profile in western Krun, hory crystalline unit. The profile passed close to the seismically active zone of NovA1/2 Kostel. The measurements were carried out to distances of about 15 km using quarry blasts near the village of Horni Rozmyl, located at the eastern margin of the crystalline unit. Smoothed P-wave travel times were interpreted using the Wiechert-Herglotz method, which yielded a 1-D velocity model of the shallow crustal structure of the crystalline unit down to a depth of 1.7 km. The P-wave velocity of the model increases from about 4.0 km/s at the surface to 5.9 km/s at a depth of 1.7 km. The superficial velocities of our model are somewhat higher than the superficial velocities of the model that is routinely used for earthquake location in the region.
