During July 7 and October 5, 1991, UCLA, U. of Wisconsin (UW), the Institute of Earth's Crust of Russian Academy of Sciences at Irkutsk and the Institute of Physics of the Earth, Moscow, conducted a joint seismic array study in the territory of the Baikal rift zone. 26 seismic stations (10 PASSCAL Reftek and 16 U. Wisconsin recorders) were installed about Lake Baikal (Figure 1 and Table 1). The UCLA field trip team installed and operated the 10 Reftek stations. All the stations were equipped with 1 Hz 3-D sensors and five of the stations were co-sited with broadband (4 Guralp and 1 STS2) seismometers. All seismographs synchronize internal clocks to signals from the Omega navigation system (locked to either Norway or Japan) which ensured that the timing error for most of the data was less than 2 ms.
This report provides information needed for others to use the unique data set recorded by the 10 UCLA Reftek stations during July 7 and October 5, 1991.
