“…There have been many studies on the earthquake, including several review studies focused on various aspects of the earthquake. Previous reviews illuminate the observations and characteristics of the coseismic rupture (Lay, 2018; Satake and Fujii, 2014; Tajima et al., 2013), provide insights gained from geodetic deformation measurements (Nishimura et al., 2014), examine the environment, structure and mechanical properties of the shallow megathrust from ocean bottom drilling (Brodsky et al., 2020), describe preseismic processes from seismicity and geodetic observations (Hasegawa & Yoshida, 2015), summarize the tsunami source mechanism (Pararas‐Carayannis, 2014), and assess post‐earthquake changes in earthquake hazard (Somerville, 2014). There are also early overviews of broad knowledge about the earthquake gained within a few years following the mainshock (Hino, 2015; Tajima et al., 2013).…”

The Tohoku-oki earthquake occurred off the Pacific coast of the Tohoku region of Japan, on March 11, 2011 (Figures 1 and 2). The official moment magnitude (Mw) of the earthquake is Mw 9.0 or 9.1 according to the Japan Meteorological Agency (JMA) (Hirose et al., 2011) and United States Geological Survey (Duputel et al., 2012), respectively. A M7-8 earthquake with rupture dimensions of about ∼100 km was expected along this segment of the subduction zone but the great 2011 event was far larger with a rupture area of about 300 × 200 km (Figure 3). The strong shaking and tsunami from the event caused devastating damage. The loss of life was as large as 19,729 and more than 121,996 houses were completely destroyed (Fire and Disaster Management Agency, 2020). Earthquake early warning and tsunami warnings were issued by the

“…To tackle this riddle, one solution is to analyze of the seismic productivity as a proxy for the slab stress conditions after a megathrust earthquake 9,10 . In that respect, the 2011/3/11 M w 9.0 Tohoku-oki earthquake is an ideal case study, since it is the best recorded megathrust earthquake of the instrumental period of seismology [11][12][13][14][15][16] and it occurred within one of the best-monitored regions of the world, Japan. Several studies conducted after the Tohoku-oki earthquake evidenced a preseismic phase 1,6,[17][18][19][20][21][22] .…”

Subduction zones are home to the world’s largest and deepest earthquakes. Recently, large-scale interactions between shallow (0-60 km) and intermediate (80-150km) seismicity have been evidenced before megathrust earthquakes along with large-scale changes in surface motion. Large-scale deformation transients following major earthquakes have also been observed possibly due to a change in slab pull or to a bending/unbending of the plates, which suggests the existence of interactions between the deep and shallow parts of the slab. In this study, we analyze the spatio-temporal variations of the Japanese seismicity before and after the 2011/3/11 Mw9.0 Tohoku-oki earthquake. We observe that the rate of the intermediate to deep (150-450km) seismicity underwent a deceleration of 55% south of the rupture zone and an acceleration of 30% north of it, coherent with the GPS surface displacements. This shows for the very first time how a megathrust earthquake can affect the stress state of the slab over a 2500 km lateral-range and a large depth range, demonstrating that earthquakes interact at a much greater scale than the surrounding rupture zone usually considered. Our vision of subduction zones must consequently be renewed as a whole, from shallow to large depths.

Abstract-With this volume of the Pure and Applied Geophysics (PAGEOPH) topical issue ''Tsunamis in the Pacific Ocean: 2011-2012'', we are pleased to present 21 new papers discussing tsunami events occurring in this two-year span. Owing to the profound impact resulting from the unique crossover of a natural and nuclear disaster, research into the 11 March 2011 Tohoku, Japan earthquake and tsunami continues; here we present 12 papers related to this event. Three papers report on detailed field survey results and updated analyses of the wave dynamics based on these surveys. Two papers explore the effects of the Tohoku tsunami on the coast of Russia. Three papers discuss the tsunami source mechanism, and four papers deal with tsunami hydrodynamics in the far field or over the wider Pacific basin. In addition, a series of five papers presents studies of four new tsunami and earthquake events occurring over this time period. This includes tsunamis in El Salvador, the Philippines, Japan and the west coast of British Columbia, Canada. Finally, we present four new papers on tsunami science, including discussions on tsunami event duration, tsunami wave amplitude, tsunami energy and tsunami recurrence.
