Abstract

Crustal motion predicted by the ICE‐3G glacial rebound model exhibits a pattern of tangential (horizontal) divergence away from the centres of uplift, which in North America and Europe are located around Hudson Bay and the Gulf of Bothnia. Tangential velocities reach peak magnitudes of 1–2 mm/yr, and must be included when predicting Very‐Long‐Baseline‐Interferometry (VLBI) baseline‐length change rates due to post‐glacial rebound. Out of 18 observed VLBI baselines examined 3 are situated such that their predicted length rates are around their 2σ uncertainties or greater. It is encouraging that 2 of these baselines exhibit predicted length rates within 2σ of the observed rates.
