Estimation of Coseismic Deformation from the Sea Level Measurements during the Mw 7.8 Earthquake of 13 Nov 2016 in New Zealand

As a consequence of the large Earthquake and following Tsunami Mw. 7.8 that occurred two days ago in New Zealand, a phenomenon, that was already identified in the case of Mw. 9.0 Tohoku Tsunami has occurred again. Infact the sea level measurement present in the area of the larger deformation has shown a behaviour typical of an uplift of about 0.95 m. In the case of the Japan event, instead, the sea level demonstrated a subsidence on the coasts of Japan, confirmed by GPS measurements.
