| Zusammenfassung |
| Analysis of the GOCE gradiometer data has shown that the Japan-Tohoku
earthquake 2011 is visible in these data. As GOCE aims at small
spatial scales, it therefore complements the accurate long wavelengths
of GRACE and we show that a combined analysis of GOCE and GRACE data
allows to map this earthquake event with unprecedented accuracy and
resolution. We present our combination of GOCE gradients and GRACE
data where we compare the results with state-of-the-art fault-slip
modeled gravity observations. We conclude that GOCE contributes to an
enhanced geophysical interpretation and gives new insights in the
observation of such a tremendous seismic event as the Tohoku-Oki 2011
earthquake. |
