We found that an intensive N-shape shock-acoustic wave with a plane waveform and with half-period of about 200 sec propagated south-eastward with a velocity of 600 m/s for distance about 1000 km. The wavefront of N-shaped disturbance was parallel with the earthquake rupture direction (from SW to NE). The main directional lobe of shock-acoustic wave emitter is directed southeastward, i.e. transversely to the rupture. We suppose that the above properties of TEC response are determined by the geodynamics of the Wenchuan earthquake. %G English %2 https://insu.hal.science/insu-02148609/document %2 https://insu.hal.science/insu-02148609/file/Afraimovich2010_Article_Near-fieldTECResponseToTheMain.pdf %L insu-02148609 %U https://insu.hal.science/insu-02148609 %~ INSU %~ UNIV-PARIS7 %~ AFRIQ %~ CNRS %~ IPGP %~ UNIV-PARIS
