Abstract

The usage of only the vector satellite survey data made it possible to detect rapidly developing anomalies of the secular variations with the foci in central Asia and Indian Ocean. It has been indicated that the field at the foci increased by several hundred nanoteslas for eight years. It is assumed that the origination of the foci was accompanied by jerks, which could be observed in this region in the mid-1990s. It is assumed that the increasing foci are the initial stage of the 60-year variation.
