Temperature dependence of extended X-ray absorption fine structure (EXAFS) is studied in the high-Tc BiPbSrCa Cu oxide superconductor. Measurements were made at the Cu K-edge in the temperature range from 26.9 to 300 K. Interatomic distances and mean square relative displacement (MSRD: σ(2) of CuO bonds are determined by the least-squares refinement. An anomalous increase in the axial component of the MSRD is found near Tc while its equatorial component decreases normally with decreasing temperature.
