The Laschamp event ended between 8000 and 20000 years ago. In several other parts of the world, excursions of the Earth's magnetic field have been seen at about this time interval, but at other parts, notably in the Aegean sea, there is no evidence for a reversal or excursion of the field during this time.By using a two dipole model, we have shown that it is possible to produce an apparent reversal at one point on the Earth's surface, which produces deviations in the direction of the magnetic field over a rather small area around the position of reversal.The two dipoles used were a centered axial dipole to model the main magnetic field, and a dipole located at the top of the core, to produce the reversed field above it. Our models show that the data from the Aegean sea are not contradictory with the Laschamp event provided that it is a pseudo reversal. We have also shown that if the non-dipole field is caused by horizontal electric currents at the top of the core, then pseudo reversals are more likely to occur at high latitudes than at low latitudes.
