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.

Detailed seismic velocity of the incoming subducting sediments in the 2004 great Sumatra earthquake rupture zone from full waveform inversion of long offset seismic data

Geophysical Research Letters, 2017
The nature of incoming sediments defines the locking mechanism on the megathrust, and the development and evolution of the accretionary wedge. Here we present results from seismic full waveform inversion of 12 km long offset seismic reflection data ...

Coulomb stress change on inland faults during megathrust earthquake cycle in southwest Japan

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 Historical documents indicate the frequent occurrence of large shallow crustal earthquakes in the overriding continental plate 50 years ...

Shallow Slow Slip Events Identified Offshore the Osa Peninsula in Southern Costa Rica From GNSS Time Series

Geophysical Research Letters, 2023
Using new continuous geodetic time series, we identify five shallow slow slip events (SSEs) offshore and beneath the Osa peninsula in southern Costa Rica. An early event was detected by one station in 2013, and two events occurring in close succession in

The Seismogenic Potential of the Southernmost Ryukyu Subduction Zone as Revealed by Historical Earthquakes and Slow Slip events

Frontiers in Earth Science, 2022
The southernmost Ryukyu subduction zone may have a geodetically inferred Mw 7.5 to 8.7 megathrust earthquake in a shallow locked region, the Ryukyu fault.

The 2016 Mw 5.9 earthquake off the southeastern coast of Mie Prefecture as an indicator of preparatory processes of the next Nankai Trough megathrust earthquake

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 ...

Megathrust Shear Modulated by Albite Metasomatism in Subduction Mélanges

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.

DONET: A Real-Time Monitoring System for Megathrust Earthquakes and Tsunamis Around Southwestern Japan [PDF]

Oceanography, 2014
DONET (Dense Ocean floor Network for Earthquakes and Tsunamis; https://www.jamstec.go.jp/donet/e/index.html) is a cabled seafloor observatory that monitors the Nankai and Tōnankai seismogenic zones, offshore southwestern Japan, in real time. In 1944, two

The hidden simplicity of subduction megathrust earthquakes

Science, 2017
Universal scaling for big quakes The amount of energy released as a large fault ruptures provides some clues about the overall size of an earthquake. Meier et al. looked at this energy release for more than 100 large earthquakes.
