| Abstract: | Data on geomagnetic field variations observed at the Patrony and Enkhaluk observatories are used to study the induction vectors in the frequency-time domain. The main features of frequency responses related to conducting zones are examined. The results of monitoring the induction vectors are presented. The induction vectors are reliably determined in the period range 600–1300 s. This range is most suitable for magnetic variation monitoring. Annual variations are discovered in the behavior of induction vectors. Their specific features are examined. Anomalous variations in the modulus of the real part of the induction vectors are identified. These variations can be due to a strong earthquake (K = 15) in southern Lake Baikal. |
