The paleomagnetic data have been comparedwith the historical geomagnetic predictions given by the GUFM1 model which spans from 1590 to 1990. Theresults show a statistical agreement between archaeomagnetic data and directions given by the geomagnetic fieldmodel. Whereas, when comparing the volcanic data with the model predictions, a marked inclination shallowing isobserved. Here, we show how this inclination shallowing is statistically presented at world-wide scale for the last400 yr with a mean inclination deviation of around 3º lower than the historical geomagnetic field model predictions.
