Mandate of Auxiliary Seismic Stations
Auxiliary seismic stations are mandated to provide data to the International Data Centre (IDC) upon request only but then with immediate availability. The purpose of this additional data is to improve location accuracy of seismic events detected by the primary seismic network. It is also to characterize the seismic sources with greater precision in order to ascertain what kind of event has taken place; for example, an earthquake or an explosion.
IMS Station Location
AS 107 is the only IMS seismic station to cover the large eastern part of the United States. The station is privately owned but can be accessed any time of the year by prior arrangement with the owners. The cave is generally open daily to the public from mid-March to mid-November.

The original seismic station was established in 1978 by the Tennessee Earthquake Information Center (TEIC).
