Data for megathrust earthquakes (2)
, 2023 Waveform data and hypocenter data of the megathrust earthquakes used in the analysis are included. 'wv.dat' contains vertical, north-south, east-west components and 'tr.dat' contains transverse components. 'hypo_thrust_wv.dat' contains the hypocentral data used for waveform analysis from the catalogue of the Japan Meteorological Agency.

Progress in Earth and Planetary Science, 2019 Megathrust earthquakes of magnitude ~ 8 and ensuing large tsunamis occur along the Nankai and Suruga troughs, central Japan, with a recurrence interval of 90–270 years since an AD 684 Hakuho earthquake.

Volcanic Subsidence Triggered by Megathrust Earthquakes
Journal of Disaster Research, 2014 Studies using spaceborne interferometric synthetic aperture radar (InSAR) analysis showed that two megathrust earthquakes – the 2011Mw9.0 Tohoku-oki earthquake in Japan and the 2010Mw8.8Maule earthquake in Chile – triggered unprecedented subsidence in multiple volcanoes. There are strong similarities in the characteristics of the surface deformation in

The Analysis of Tsunami Vertical Shelter in Padang City
, 2014 Padang is a coastal city, which is located opposite to the Indian Ocean. Just across Padang city there are areas of subduction, which can trigger a powerful earthquake and generate tsunami.

Link between the Nankai underthrust turbidites and shallow slow earthquakes
Scientific Reports, 2023 Trench sediments such as pelagic clay or terrigenous turbidites have long been invoked to explain the seismogenic behavior of the megathrust fault (i.e., décollement).

Multi-Hazard Portfolio Loss Estimation for Time-Dependent Shaking and Tsunami Hazards
Frontiers in Earth Science, 2020 Megathrust subduction earthquakes generate intense ground shaking and massive tsunami waves, posing major threat to coastal communities. The occurrence of such devastating seismic events is uncertain and depends on their recurrence characteristics (e.g.,

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 ...

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such
