Summary: Research has shown that there were indications of a potential great megathrust earthquake in NE Japan before the 2011 Tohoku earthquake, but a consensus assessment of the hazard was lacking. Since the earthquake, studies have made significant progress in revealing aspects such as coseismic rupture, aftershocks, and slow earthquakes.

Summary: Deep-sea turbidite deposits are valuable tools for submarine paleoseismology. By analyzing the event deposits from the 2011 Tohoku-oki earthquake and tsunami, researchers found that the deposits originated from multiple sources, indicating widespread seafloor disturbances. Different types of event deposits reflect varying sediment transport pathways, with limited long-distance transport observed despite the wide spatial distribution.

Summary: The near-trench coseismic rupture behavior of the 2011 Tohoku-Oki earthquake is poorly understood due to lack of near-field observations. This study used differential bathymetry estimates with improved horizontal resolutions to investigate the near-trench coseismic slip behaviors. The results revealed a velocity-strengthening behavior in the shallow fault and significant off-fault deformation features near the backstop interface outcrop.

Summary: This study presents the anomalities of total electron content in the ionosphere before the 2011 M(w)9.0 Tohoku-oki earthquake, observed in northern Australia by the Global Navigation Satellite System (GNSS) stations. The onset time of the anomaly, determined by the Akaike's information criterion, is very close to the time observed in Japan. The positive TEC anomalies in Australia appear on the same longitude as the land area of NE Japan, supporting the model that electric fields within the ionosphere redistribute the electrons before large earthquakes.

Summary: The 2011 Tohoku-oki tsunami caused massive damage along the northern Japanese Aomori coast, with the coastal control area being inundated up to 550 m inland. A previously undocumented woody-organic tsunami deposit was discovered, improving understanding of the documented part of the tsunami inundation and reducing underestimation.

Summary: Fluid behavior in the crust plays a key role in earthquake occurrence by reducing fault strength and leading to localized high seismic wave attenuation in fault zones. This study examined near-source attenuation in a region of intense swarm activity triggered by fluid movement following the 2011 Tohoku-Oki earthquake in Japan. The method used in this study may be helpful in detecting high pore pressure anomalies at depth and understanding their relationship to earthquake occurrence.

Summary: By focusing on high-precision GNSS data processing and analysis, the study reveals the dynamic evolution of tectonics and crustal deformation along subduction zones. Common Mode Errors are removed, deformation signals are extracted, and regional spatiotemporal filtering is utilized to comprehensively display crustal motion characteristics.

Summary: This study investigated the impact of the Tohoku-Oki earthquake on South Korea using GNSS measurements. The research found that during the earthquake, there were significant displacements and deformation. After the earthquake, the South Korean Peninsula experienced extensional deformation and an effective rotational change.

Summary: It is found that colored noise in GNSS time series has significant impact on parameter estimation of general linear trajectory models. To overcome this issue, maximum likelihood estimation is used to estimate the colored noise and a nonlinear least square algorithm with colored noise as the stochastic model is employed to calculate timescale parameters. The method is validated through simulation experiments and has shown significant improvements in reducing iteration times and decreasing parameter estimation deviations compared to traditional methods.

Summary: The study on decaying post-seismic deformation on the Korean Peninsula indicates that crustal movement is gradually returning to its pre-earthquake motion, with the recovery pattern influenced by regional geologic structures and time.

Summary: After the 2011 Tohoku-Oki earthquake, the Japan Meteorological Agency made significant improvements to their earthquake early warning system by implementing new ground motion prediction methods and incorporating new observation facilities. These updates enhanced the accuracy and timeliness of earthquake predictions, showing substantial progress over the 10 years since the Tohoku-Oki earthquake.

Summary: This study used seismic data to obtain more detailed images and related information of the 2011 Tohoku-Oki earthquake, revealing that the pore-fluid pressure along the decollement and backstop interface is generally higher than the hydrostatic pressure, especially in the decollement. This high pressure leads to fault rupture and earthquake occurrence.

Summary: Repeated multibeam bathymetric surveys were crucial in understanding the distribution of coseismic seafloor displacement caused by the 2011 Tohoku-oki earthquake. Large seafloor displacements were observed in the main rupture area, while smaller displacements were detected tens of kilometers away from the primary rupture zone.

Summary: The 2011 Tohoku-oki tsunami left a characteristic geochemical signature in the sediments of the Misawa harbor on the Aomori coastline, with specific compounds illustrating different emission sources and distribution during the tsunami. Petrogenic-derived markers provide information about tsunami-related destruction, sewage-derived compounds were widely distributed from a diffuse source, and old burden markers signal erosion and rearrangement of contaminants prior to the tsunami.
