Abstract

Changes in the local magnetic field associated with volcanic thermal activity on Kadovar Island, Papua New Guinea, were measured over a one-year period, 1976/77. The magnetic field changes were highly localised near vents and were quite shallow. They were most likely produced by thermal demagnetisation rather than through piezomagnetic effects.
