Two types of volcanic tremor were observed during July-December, 1963. One is accompanied by the eruptions in August and October and the other is associated with no eruptive activity. Spacial distribution of tremor amplitude in the case of the October eruption and amplitude spectra for various cases were studied from the records obtained by densely located seismometers in and around Kilauea caldera. The results imply that a) before and during the eruption, movement or feeding of magma occurs beneath the region of Halemaumau, b) lava seems to flow through a more or less continuous conduit from beneath Halemaumau to the east rift zone, and c) long-period tremor (2 sec.) is of deep origin and short period tremor seems to be related with surface lava extrusion.
