A high-resolution map of surface displacements indicates that the 2017 Chiapas earthquake caused substantial creep along a segment of the San Andreas Fault, located 3,000 kilometers away.Read More »Geochemistry, Mineralogy, Volcanology
Molecular dynamics calculations suggest that molten hydrogen-bearing iron peroxide (FeO2Hx) may produce the ultra-low velocity zones that occur at the core-mantle boundary.Read More »Natural Hazards
Granular flows are important in geophysics to the pyroclastic flow, debris flow, and avalanches. Understanding their complex and rich physics is therefore important in simulating their dynamics.Read More »Geology & Geophysics
