Fig. 12From: Consistent estimation of strain-rate fields from GNSS velocity data using basis function expansion with ABICDiscrepancy in strain-rate fields estimated by Shen’s method with different values of D. The discrepancy between the dilatation rate directly obtained by Shen’s method and that calculated from the velocity field through differentiation is shown. Bottom panels show enlarged views around the Izu Islands; the location is indicated by boxes in the top panels. Open circles represent the GNSS stations. Positive dilatation represents expansionBack to article page
