Geomagnetic and seismological data collected from Scott Base, Cape Evans (Ross Island) and Lake Vanda

Three component recordings of geomagnetic field variations are made, analysed and transmitted to international databases and individual researchers as appropriate. Seismological data have been recorded since 1957 at Scott Base and since 1986 near Vanda Station in the Dry Valleys (VNDA) .The VNDA program was taken over by the USGS (run out of Albuquerque) in 2002 when US and international institutions linked the Dry Valley seismographs into an international telemetered global seismograph network and analysis system.

Three component seismological recordings of ground motion are made and analysed for teleseismic events and the location of earthquakes around the globe. This research project forms part of a global networks of observatory seismographs and magnetometers which provide i) information for the study of earthquakes and earth structure and ii) information on the variation of the earth's geomagnetic field on global and regional scales.

A 3 component broadband seismometer (SBA) is still located at Scott Base. It forms a vital part of the global network and in the case of seismological or earthquake studies, the Scott Base seismographs are particularly important as the station lies close to the azimuth of the plate boundary and major active tectonic features through New Zealand. The instrument is operated throughout the year and maintained every year.
