Research Activities

We investigated the detailed 3-D structure of the source zone of the great 2011 Tohoku-oki earthquake (Mw 9.0) (Zhao et al., 2011; Liu & Zhao, 2018; Hua & Zhao et al., 2020).

We proposed the big mantle wedge (BMW) model to explain the origin of the intraplate volcanism in the East Asian region (Zhao et al., 2004, 2009).

We determined the first 3-D seismic tomography of the lunar interior (Zhao et al., 2008, 2012).
