Change of deep subduction seismicity after a large megathrust earthquake [PDF]
Nature Communications, 2023 Abstract Subduction zones are home to the world’s largest and deepest earthquakes. Recently, large-scale interactions between shallow (0-60 km) and intermediate (80-150 km) seismicity have been evidenced during the interseismic period but also before and after megathrust earthquakes along with large-scale changes in surface motion ...

Seismic rate variations prior to the 2010 Maule, Chile MW 8.8 giant megathrust earthquake [PDF]
Scientific Reports, 2021 The MW 8.8 Maule earthquake is the largest well-recorded megathrust earthquake reported in South America. It is known to have had very few foreshocks due to its locking degree, and a strong aftershock activity.

Progress in Earth and Planetary Science, 2018 Megathrust earthquakes have occurred repeatedly at intervals of 100 to 150 years along the Nankai Trough, situated in the southwest of Japan. Given that it has been 70 years since the last event, the occurrence of the next devastating earthquake is ...

Geophysical Research Letters, 2018 We investigated VP/VS changes in the upper crust of the Japanese islands after the 2011 MW9.0 Tohoku‐Oki megathrust earthquake. Abrupt VP/VS changes with azimuth‐dependent variations were observed after the megathrust earthquake. The VP/VS changes ranged

Coseismic seafloor deformation in the trench region during the Mw8.8 Maule megathrust earthquake. [PDF]
Sci Rep, 2017 The Mw 8.8 megathrust earthquake that occurred on 27 February 2010 offshore the Maule region of central Chile triggered a destructive tsunami. Whether the earthquake rupture extended to the shallow part of the plate boundary near the trench remains ...

Continuing megathrust earthquake potential in Chile after the 2014 Iquique earthquake [PDF]
Nature, 2014 The seismic gap theory identifies regions of elevated hazard based on a lack of recent seismicity in comparison with other portions of a fault. It has successfully explained past earthquakes (see, for example, ref. 2) and is useful for qualitatively describing where large earthquakes might occur.

Observation of Earth's free oscillation by dense GPS array: after the 2011 Tohoku megathrust earthquake. [PDF]
Sci Rep, 2012 Day-scale Earth’s free oscillation after large earthquakes has been detected by underground instruments such as strainmeters, gravimeters and seismometers, to investigate Earth’s internal structure, geodynamics, and source properties of earthquakes. Here

Comprehensive earthquake-induced landslide inventory dataset of the 2010 Chile megathrust earthquake [PDF]
Data in BriefChile is one of the most seismically active countries on Earth and is often associated with cascading hazards, such as ground shaking, liquefaction, tsunamis, and coseismic landslides. Additionally, removal mass is a global hazard with devastating impacts resulting in thousands of fatalities every year, substantial economic losses, and long-term ...

Evidence of megathrust earthquakes and seismic supercycles in subtropical Japan from millennia-old coral microatolls [PDF]
Nature CommunicationsMegathrust earthquakes in subduction zones often go unreported because they are rare and the historical record is short. On the Ryukyu subduction zone of southwestern Japan, unlike neighboring Nankai Trough, the history and future potential of great ...
