Japan Tohoku Earthquake and Tsunami - Measurements with Ny-Ålesund Super Conducting Gravimeter

Japan Tsunami Knock-out of Polar Instruments

Credit NOAA

Above you see the ocean wide tsunami wave propagation. It was not that kind of wave that knocked out the geodetic instrument situated close to the North Pole though. It was the gravitational consequences of all that mass movement, both the continental plates and the immense water body.

See the graphs from Ny-Ålesund here.
