Results of travel-time curve calculation have been presented for P- and S-waves in the interval of epicentral distances
10-350 km by the records of 25 local earthquakes (mb=2,0-3,4; h0=2-7 km) and 43 industrial explosions. Comparison
of calculated hodograph with global hodograph (h0=0 km) has been conducted. It has been found that within the limits of the
studied interval of distances differences with Kennett hodograph are not essential and do not exceed 1,5 s (P) and 2 s (S),
with hodograph of Jeffreys-Bullen differences are considerable within the distances less than 100 km - 3-6 s (P) and 4-8 s (S). The
obtained hodograph has been compared with calculated earlier for the distances up to 500 km by the records of the earthquakes
(mb=2,0-4,0; h0=2-10 km) of the Carpathian region, the western part of the East-European platform and industrial explosions.
