The Seismic Array Laboratory is a large observation system for array seismological experiments, which is supported by the Knowledge Innovation Program of the Chinese Academy of Sciences. The primary functions of the laboratory are to collect seismic data of earthquakes and man-made sources, by means of portable seismic arrays in the field, and to manage the collected seismic data indoors. The laboratory may provide instrumental and technical support for portable seismic arrays aiming toward the crustal and upper-mantle structures of the Chinese continent and the structure of the Earth’s deep interior, as well as seismic data collaboration. The laboratory currently has 332 sets of broadband seismometers, including 232 sets of imported ones and 100 sets of domestic ones. With its professional technicians and equipment, the laboratory is able to provide services related to the inspection, maintenance and development of seismometers, as well as standard processing of seismic data.
