Intermediate wavelength seismology and the NARS experiment.

Describes the scientific aims of the NARS experiment and summarize the most important characteristics of the array. Briefly reviews the functioning of the array in the first 2 yr of its existence. The response rate (the number of stations with a successfully triggered recording of a large earthquake) has in this time slowly grown to about 70%. The early experiences with NARS have shown that the operation of an autonomous digital array is realizable at low cost. Concludes with a set of recommendations that new digital broad-band networks may turn to good account, and a few preliminary results that give a representative impression of the kind of new data that may be expected from the NARS array in the near future. -from Authors
