Volcanoes on the Moon


THE recent observations by Kozyrev1 of phenomena on the surface of the Moon, which he ascribed to volcanic activity, have stimulated a considerable amount of conjecture. Fremlin2 has put forward an hypothesis based on radioactive heating from the interior and an assumed very low thermal conductivity of the lunar surface. This model leads to the prediction of sub-surface temperatures high enough to melt basaltic rocks. Objections to this hypothesis have been pointed out by Jaeger3.
