The paper, entitled "Structural control on the Tohoku earthquake rupture process investigated by 3D FEM, tsunami and geodetic data", was published this month on Scientifc Reports and is available here.
The lead authors are from ASTARTE's partner Istituto Nazionale di Geofisica e Vulcanologia (INGV), in Italy.
This article is a contribution to ASTARTE's work package 3.
The ASTARTE #1 geophysical marine survey took place from the 19th-29th May 2014 onboard the vessel Xu-Nauta.
The mission was conducted by IPMA with Pedro Terrinha as chief scientist together with researchers from LNEG. João Noiva (IPMA) will coordinate data processing efforts.
The scientists collected multichannel seismic data, covering more than 300 nautical miles (now under processing), in the offshore of Quarteira, Algarve, South of Portugal. In this area, the historical documents of the 1755 Lisbon tsunami report that wave heights exceeded 10m. The pre-collected vibro and gravity cores of the area (existing at IPMA) will serve as calibration for stratigraphy and detection of backwash tsunami deposits.
ASTARTE will have several contributions on display at the European Geosciences Union General Assembly, taking place in Vienna, Austria, in April, 2014.
