Pemodelan Segmentasi Mentawai-Pagai: Studi Kasus Gempa Megathrust di Indonesia
Jurnal Geosains dan Remote Sensing, 2020 Gempa yang terjadi pada tanggal 25 Oktober di Pulau Mentawai merupakan gempa megathrust segmentasi Mentawai-Pagai. Segmentasi megathrus ini memiliki sejarah gempa yang terjadi sebelumnya yaitu pada tahun 1797 dan 1833.

Megathrust Shear Modulated by Albite Metasomatism in Subduction Mélanges [PDF]
Geochemistry, Geophysics, Geosystems, 2022 Aseismic megathrust slip downdip of the seismogenic zone is accommodated by either steady creep or episodic slow slip events (SSEs). However, the geological conditions defining the rheology of megathrust slip remain elusive.

Offshore Landward Motion Shortly After a Subduction Earthquake Implies Rapid Relocking of the Shallow Megathrust [PDF]
Geophysical Research Letters, 2023 Geodetic observations after large subduction earthquakes reflect multiple postseismic processes, including megathrust relocking. The timing of relocking and the observational constraints on it are unclear.

Seismic and aseismic slip on the Central Peru megathrust [PDF]
Nature, 2010 Slip on a subduction megathrust can be seismic or aseismic, with the two modes of slip complementing each other in time and space to accommodate the long-term plate motions. Although slip is almost purely aseismic at depths greater than about 40 km, heterogeneous surface strain suggests that both modes of slip occur at shallower depths, with aseismic ...

Coulomb stress change on inland faults during megathrust earthquake cycle in southwest Japan [PDF]
Earth, Planets and Space, 2020 In the subduction zone, megathrust earthquakes may modulate the shallow crustal seismicity in the overriding plate. Historical documents indicate the frequent occurrence of large shallow crustal earthquakes in the overriding continental plate 50 years ...

Asthenosphere Flow Modulated by Megathrust Earthquake Cycles [PDF]
Geophysical Research Letters, 2018 Abstract Subduction megathrusts develop the largest earthquakes, often close to large population centers. Understanding the dynamics of deformation at subduction zones is therefore important to better assess seismic hazards. Here I develop consistent earthquake cycle simulations that incorporate localized and distributed deformation ...

THE SUNDA MEGATHRUST — PAST, PRESENT AND FUTURE
Journal of Earthquake and Tsunami, 2007 After lying dormant for about a thousand years, sudden slippage of a 1600-km long section of the Sunda megathrust fault caused uplift of the seafloor between Aceh and Myanmar, resulting in a great earthquake and the horrific Indian Ocean tsunami of 2004.

Impact of Upper‐Plate Faulting on Megathrust Foreshocks: Insights From the 2014 Iquique Earthquake [PDF]
Geophysical Research LettersThe role of upper‐plate faulting in the seismic cycle of large megathrust earthquakes remains poorly understood. We use quasi‐dynamic numerical simulations of seismic cycles to analyze the interaction between crustal faulting and the foreshock sequence ...

SeismicaOn October 19, 2020, the Mw7.6 Sand Point earthquake struck south of the Shumagin Islands in Alaska. Moment tensors indicate the earthquake was primarily strike-slip, yet the event produced an enigmatic tsunami that was larger and more widespread than ...
