2. Recording of the Sumatra
earthquake with the
superconducting gravimeter from the station Walferdange, Luxembourg
(49.66 N
6.15 E) after removing the first arrival waves. The biggest blusters
correspond
to aftershocks. The noise level after the earthquake increases due to
the
excitation of normal modes of the Earth. Figure
