Comprehensive earthquake-induced landslide inventory dataset of the 2010 Chile megathrust earthquake. [PDF]

Data Brief
Chile 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 ...

Mega-earthquakes rupture flat megathrusts [PDF]

Science, 2016
Mega-earthquakes go the flat way Megathrust faults in subduction zones cause large and damaging earthquakes. Bletery et al. argue that certain geometric features of the subduction zones relate to earthquake size. The key parameter is the curvature of the megathrust.

Nucleation process of the 2011 northern Nagano earthquake from nearby seismic observations

Scientific Reports, 2021
The 2011 magnitude (M) 9.0 Tohoku-oki earthquake was followed by seismicity activation in inland areas throughout Japan. An outstanding case is the M6.2 Northern Nagano earthquake, central Japan, occurred 13-h after the megathrust event, approximately ...

Change of deep subduction seismicity after a large megathrust earthquake

, 2023
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

Learning from a Disastrous Megathrust Earthquake

Eos, 2021
Ten years of interdisciplinary studies since the disastrous Tohoku-oki earthquake have improved our knowledge of earthquake-cycle processes and hazard, but prediction of such events remains elusive.

Limited Shallow Slip for the 2020 Simeonof Earthquake, Alaska, Constrained by GNSS‐Acoustic

Geophysical Research Letters, 2023
The 22 July 2020 Mw7.8 Simeonof earthquake was a deep megathrust event that ruptured along the Shumagin segment of the Alaska‐Aleutian subduction zone. This earthquake occurred ∼250 km from a seafloor geodetic GNSS‐Acoustic site IVB1, where we observed a

Probabilistic Tsunami Hazard Analysis for Vancouver Island Coast Using Stochastic Rupture Models for the Cascadia Subduction Earthquakes

GeoHazards, 2023
Tsunami hazard analysis is an essential step for designing buildings and infrastructure and for safeguarding people and assets in coastal areas. Coastal communities on Vancouver Island are under threat from the Cascadia megathrust earthquakes and ...

The roles of quartz and water in controlling unstable slip in phyllosilicate-rich megathrust fault gouges [PDF]

, 2014
A recent microphysical model for the steady-state frictional behaviour of wet illite/quartz gouges in subduction megathrust settings predicts that velocity-weakening in the seismogenic zone results from a competition between shear-induced dilatation and ...
