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 …

Applying probabilistic methods to infrequent but devastating natural events is intrinsically
challenging. For tsunami analyses, a suite of geophysical assessments should be in …

A multiple time window inversion of 53 high‐sampling tsunami waveforms on ocean‐bottom
pressure, Global Positioning System, coastal wave, and tide gauges shows a temporal and …

We detected and measured coseismic displacement caused by the 11 March 2011 Tohoku-
Oki earthquake [moment magnitude (MW) 9.0] by using multibeam bathymetric surveys. The …

Many studies have modeled the Tohoku tsunami of March 11, 2011 as being due entirely to
slip on an earthquake fault, but the following discrepancies suggest that further research is …

We describe two transient slow slip events that occurred before the 2011 Tohoku-Oki
earthquake. The first transient crustal deformation, which occurred over a period of a week in …

The mechanics of great subduction earthquakes are influenced by the frictional properties,
structure, and composition of the plate-boundary fault. We present observations of the …

Large coseismic slip was thought to be unlikely to occur on the shallow portions of plate-
boundary thrusts, but the 11 March 2011 Tohoku-Oki earthquake [moment magnitude (M …

The shallower portions of subduction zone megathrust faults host Earth's most hazardous
tsunamigenic earthquakes, yet understanding how and when they slip remains elusive …

On 11 March 2011, the devastating M9. 0 Tohoku Earthquake occurred on the interface of
the subducting Pacific plate, and was followed by a huge tsunami that killed about 20,000 …
