Kilauea volcano has high seismicity, most of which is associated with specific fault zones on the volcano and with movement of magma at depth (Koyanagi and Endo, 1971; Koyanagi et al., 1976). Certain groups of earthquakes have been observed at very shallow depths, however, and some of these have been concentrated in a zone that lies near the resistivity anomaly and the center of inflation. The data show that this shallow activity, which takes place at depths of a few kilometers, lies on a projection of the plane passing through the deeper loci of activity that are believed to be associated with movement of magma. Is the shallow activity associated with movement of fluids other than magma? Ward (1972) has shown that hydrothermal systems can give rise to swarms of micro-earthquakes. It therefore seems reasonable to assume that the shallow earthquakes at Kilauea may also be associated with the movement of hydrothermal fluids.
