Since predictions need not be correct my statement that the displacement *is* caused by the earthquake was not careful enough. But the earthquake *may* be the cause of (part of) the observation. In any case we further analyze our results, and I am interested in the results from specialists in earthquakes and polar motion excitation that will certainly be presented at the upcoming meetings. Best regards Urs Hugentobler
