Propagation paths are calculated for weak hydromagnetic shock waves (fast mode) from a point source lower than 3000km above the sea level. It is shown that the shock waves of this type have a tendency to propagate easily in the direction of the geomagnetic meridian. The results are compared with the observed geomagnetic disturbances due to the small scale high altitude nuclear explosion (Argus III). A qualitative agreement is obtained between the theoretical and the observational results.
