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.

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.,

Continuing megathrust earthquake potential in Chile after the 2014 Iquique earthquake
Nature, 2014 The seismic gap theory identifies regions of elevated hazard based on a lack of recent seismicity in comparison with other portions of a fault. It has successfully explained past earthquakes (see, for example, ref. 2) and is useful for qualitatively describing where large earthquakes might occur.

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic afterslip associated with the 2025 Mw 8.8 Kamchatka earthquake.

Regional changes in streamflow after a megathrust earthquake [PDF]
Earth and Planetary Science Letters, 2017 Abstract Moderate to large earthquakes can increase the amount of water feeding stream flows, mobilizing excess water from deep groundwater, shallow groundwater, or the vadose zone. Here we examine the regional pattern of streamflow response to the Maule M8.8 earthquake across Chile's diverse topographic and hydro-climatic gradients.

Geophysical Research Letters, 2012 On February 27th 2010, a MW8.8 earthquake struck the coast of south‐central Chile, rupturing ∼500 km along the subduction interface. Here we estimate the amount of seismically‐released afterslip (SRA) and the mechanisms underlying the distribution of ...

Earthquake and Tsunami Potential of the Hikurangi Subduction Thrust, New Zealand: Insights from Paleoseismology, GPS, and Tsunami Modeling [PDF]
Oceanography, 2014 The Hikurangi subduction margin, where the Pacific Plate subducts beneath the North Island of New Zealand, poses a major seismic and tsunami hazard to the New Zealand region, but its seismic and tsunami potential is largely unknown because of New Zealand'

The 2025 Mw 8.8 Kamchatka Megathrust: A Rapid Recurrence With Complex Heterogeneous Rupture
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract On 29 July 2025, a Mw 8.8 earthquake struck Kamchatka, ∼50 km from the 1952 Mw 9.0 megathrust hypocenter, exhibiting a comparable aftershock zone. We resolve the kinematic rupture process and slip distribution by combining teleseismic waveforms with high‐quality tsunami data.
