Broadband Seismometer Most of our array involves the use of instruments like this one, which are capable of recording ground motion at even very long periods. Such data are necessary for tomographic imaging and full exploitation of the information carried in far traveled teleseismic waves. These instruments require careful handling and installation into a temperature-stabilized vault. This usually involves burial of the instrument in a meter-deep pit containing an insulated enclosure.
