RAPID - Collaborative Research - Offshore impacts of the Tohoku-Oki earthquake on seafloor deformati

Lead PI: Dr. Cecilia M. McHugh , Mr. Leonardo Seeber

Unit Affiliation: Marine Geology & Geophysics, Lamont-Doherty Earth Observatory (LDEO)

August 2011 - July 2013

Asia ; Japan
Project Type: Research

DESCRIPTION: The rupture area of the Tohoku-Oki earthquake has been extensively surveyed so this project will precisely quantify the morphological, sedimentological, and structural changes that may occur along a submerged plate boundary during a large earthquake.
