Abstract

Highlights•Develop a new elastic reverse-time migration method for multi-component seismic data.•Separate elastic wavefields along both horizontal and vertical directions.•Employ an imaging condition using separated wavefields.•Compute Poynting vectors using separated wavefields to improve polarity correction.•The new migration method can directly image steeply-dipping faults.
