Unusually large tsunamis frequent a currently creeping part of the Aleutian megathrust

Geophysical Research Letters, 2016
Current models used to assess earthquake and tsunami hazards are inadequate where creep dominates a subduction megathrust. Here we report geological evidence for large tsunamis, occurring on average every 300–340 years, near the source areas of the 1946 ...

Evaluation of the Potential Geological and Socioeconomic Impacts of the Imminent Cascadia Megathrust Earthquake [PDF]

, 2020
The Cascadia Subduction Zone on the northwest coast of the United States poses the threat of a devastating megathrust earthquake and subsequent tsunami damaging coastal populations.

Obliquity limit of megathrust earthquakes

The largest earthquakes occur on subduction-zone megathrusts, where plates commonly converge obliquely to trenches and generate trench-parallel strain. How this strain is partitioned between megathrust slip and upper-plate deformation remains uncertain ...

Contribution of Slow Earthquake Study for Assessing the Occurrence Potential of Megathrust Earthquakes

Journal of Disaster Research, 2014
Studies of slow earthquakes during the last decade have suggested a relationship between various types of earthquakes occurring at the interface between subducting oceanic plates and overlying continental plates. Such a relationship has been postulated for slow earthquakes, which are distributed between the stable sliding zone and the locked zone, and ...

PREDICTION OF MEGATHRUST IMPACT ON SEISMIC RESPONSE IN SELEBAR DISTRICT OF BENGKULU CITY

Jurnal Pensil
Bengkulu City was hit by major earthquakes in 2000 and 2007 with magnitudes of 7.9 Mw and 8.6 Mw. In 2022 BMKG Baai Island, Bengkulu City, said that there is a potential for an earthquake with a maximum magnitude of 8.9.
