A megathrust earthquake genesis process observed by a Global Positioning System

open access: yes, 2023
Japan's GPS observed the fifteen-month megathrust earthquake genesis process of the 2011 Tohoku M9, suggesting the real-time predictability of such events.Comment: 79 pages, 45 figures, an update from part of the patent (130 pages, 85 figures) here ...

The 2010 Mw 8.8 Maule megathrust earthquake of Central Chile, monitored by GPS

open access: yes, 2011
Large earthquakes produce crustal deformation that can be quantified by geodetic measurements, allowing for the determination of the slip distribution on the fault.

Seismic‐afterslip characterization of the 2010 MW 8.8 Maule, Chile, earthquake based on moment tensor inversion

open access: yesGeophysical 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]

open access: yesOceanography, 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'

Tsunami Traveling Ionospheric Disturbances Triggered by the 29 July 2025 Mw 8.8 Kamchatka Earthquake Observed in Japan and Taiwan

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated notable seismic and tsunami waves. The total electron content (TEC) derived by more than 1,400 ground‐based global navigation satellite system (GNSS) receiving stations in Japan and Taiwan is employed to examine the spatiotemporal evolution of seismic‐ and tsunami‐traveling ionospheric ...

Structural heterogeneity in source zones of the 2018 Anchorage intraslab earthquake and the 1964 Alaska megathrust earthquake

open access: yes, 2019
3-D seismic structures (Vp, Vs and Poisson’s ratio) in and around the source zones of the 2018 Anchorage intraslab earthquake (Mw 7.1) and the 1964 Alaska megathrust earthquake (Mw 9 ...

Evolution of Coupled Seismic‐Aseismic Slip During the 2025 Mw 6.8 Sanriku‐Oki, Japan, Megathrust Sequence

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 9 November 2025, a Mw 6.8 Sanriku‐Oki earthquake struck a Japan Trench segment with inferred recurrent aseismic slip and Mw ∼7 earthquakes. Using S‐net seafloor data, we examine the preparatory and post‐mainshock evolution of this foreshock–mainshock–aftershock sequence.

The Influence of Depth‐Varying Elastic Properties of the Upper Plate on Megathrust Earthquake Rupture Dynamics and Tsunamigenesis [PDF]

open access: yes, 2021
International audienceMegathrust earthquakes are strongly influenced by the elastic properties of rocks surrounding the fault. In contrast to friction, these properties can be derived in situ from geophysical measurements along the seismogenic zone ...

Impact of a tsunami generated at the Lesser Antilles subduction zone on the Northern Atlantic Ocean coastlines [PDF]

open access: yesAdvances in Geosciences, 2014
On 11 March 2011, a Mw ~ 9.0 megathrust earthquake occurred off the coast of Tohoku, triggering a catastrophic tsunami reaching heights of 10 m and more in some places and resulting in lots of casualties and destructions.
