Along a N30E striking profile in central Java, Indonesia we recorded
broadband magnetotelluric data at 8 sites in the period range 0.01
s - 10000 s. A preliminary analysis of apparent resistivity, phase
and magnetic transfer function data favours a one-dimensional interpretation
of most sites for the upper 3-5 km of the crust and a two- or three-dimensional
structure for the lower crust. Several conductive features can be
distinguished: (i) a strong 'ocean effect' at the southern most site,
(ii) a zone of very high conductivity in the central part of the
profile, and (iii) a conductor in the north that cannot be caused
by the shallow Java sea. We discuss tentatively causes for these
anomalies. The conductor in the central part of the profile is probably
connected with volcanic or geothermal activity, while the anomaly
in the north could be an expression of processes associated with
an active fault zone.
