Natural hazards (NH), such as earthquakes, tsunamis, volcanic eruptions, and severe
tropospheric weather events, generate acoustic and gravity waves that propagate upward …

Geodesy, the oldest science, has become an important discipline in the geosciences, in
large part by enhancing Global Positioning System (GPS) capabilities over the last 35 years …

Global seismographic networks (GSNs) emerged during the late nineteenth and early
twentieth centuries, facilitated by seminal international developments in theory, technology …

Subduction zone megathrust faults host Earth's largest earthquakes, along with multitudes of
smaller events that contribute to plate convergence. An understanding of the faulting …

Abstract The 2011 March 11 Tohoku-oki great (Mw 9.1) earthquake ruptured the plate
boundary megathrust fault offshore of northern Honshu with estimates of shallow slip of 50 m …

Large earthquakes are usually assumed to release all of the strain accumulated since the
previous event, implying a reduced seismic hazard after them. However, long records of …

Rapid and reliable estimation of large earthquake magnitude (above 8) is key to mitigating
the risks associated with strong shaking and tsunamis. Standard early warning systems …

The 2004 Sumatra-Andaman and 2011 Tohoku-Oki earthquakes highlighted gaps in our
understanding of mega-earthquake rupture processes and the factors controlling their global …

Abstract The 2011 Mw 9.0 Tohoku‐oki earthquake is one of the world's best‐recorded
ruptures. In the aftermath of this devastating event, it is important to learn from the complete …

Rapid near‐source earthquake source modeling relying only on strong motion data is
limited by instrumental offsets and magnitude saturation, adversely affecting subsequent …
