Geophysics and Geodynamics
Geophysics and geodynamics researches employ a variety of the state-of-the-art geophysical methods to investigate (1) complex structures and their distribution in Earth’s interior, (2) ocean-bottom seismology, (3) mechanism and dynamics of slab subduction and convection of planetary mantle and lithosphere, (4) physical and chemical properties of deep Earth materials, (5) evolution of Earth’s gravitational and magnetic fields with applications to natural hazards and environments.

Seismology
Seismology uses information that waves carry from earthquakes and various natural sources (e.g. ocean waves) to study the physical properties and structures of sources and subsurface medium. With that, we investigate their relationships to wide-spectrum topics of active faults, orogenic process, volcanic magmatic system, inner core evolution, etc. from shallow to deep Earth.

Geology and Active Tectonics
The research fields of geology and active tectonics at IES involve topics of various time and space scales for understanding the processes of crustal evolution and recent crustal deformation and surface processes. Research on orogenic belts and mountain building in IES aims at establishing magmatic records by systematic geochronological and geochemical analyses, and elucidating underground structure and earthquake source characteristics by deploying portable broadband seismic networks. ...
