Abstract
Surface-wave magnitudes (M8) of 4.1 and 3.2 are determined for two events in southern Algeria. The corresponding body-wave magnitudes (mb) are 5.8 and 4.9, respectively. The surface waves from these events are much smaller than would be expected from most earthquakes of comparable body-wave magnitudes, which fact suggests that these waves were generated by underground explosions.Keywords
