Abstract

Abstract: A transient deformation method based on relative strength index is proposed in this paper. In the case study, RSI is used in the transient deformation detection from the time series of GPS continuous tracking stations located in the Cascadia subduction zone of North America. The results show that the RSI method can effectively detect the transient deformation in each series, and obtain the start time, end time, duration and slippage of the transient deformation. The variance of residual time series with the transient deviation correction are significantly smaller than the ones without the transient deviation correction.

Key words: relative strength index, transient deformation, GPS coordinate time series, signal detection
