The establishment of seismological and magnetic observatories at Heard Island is described. Brief descriptions and photographs of the huts and instruments are given. Earthquake phases recorded between April 1951 and February 1952 are listed, as are absolute magnetic observations made between July 1951 and January 1952. Although Heard Island has two active volcanic craters, the region is not very active seismically. Only two near earthquakes were recorded, both probably 2°.9 distant along the Kerguelen ridge. The absolute magnetic observations showed that the high rate of secular change in declination and horizontal intensity is continuing.
