The gross structure of the moon may be determined from natural seismic events, supplemented by artificial impacts at close ranges. The moon has a rigid mantle below a layered crust. At a depth of 500-850 km there is a decrease in S-velocity and an increase in attenuation; the preferred depth for this change is 600 km. The simultaneous occurrence of these phenomena indicates a small amount of melt below this depth. Deep focus moonquakes lie below the decrease in S-velocity at depths of about 650-950 km. Good estimates of the depth of shallow focus moonquakes are not available, but they may be releasing tectonic stress.
