New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Large fault slip peaking at trench in the 2011 Tohoku-oki earthquake

Nature Communications, 2017
The 2011 Tohoku-oki earthquake slip occurred on the shallowest part of the megathrust, but the nature of the shallow slip has been poorly constrained. Here, the authors model bathymetry differences before and after the earthquake to determine that the ...

Low Heat Flow Near the Deformation Front of the Northern Hikurangi Margin Revealed by Deep Borehole Observatories

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Deep borehole observatories installed during IODP Expedition 375 at Sites U1518 and U1519 along the northern Hikurangi subduction margin offshore New Zealand provide new constraints on the thermal structure of the frontal prism, where frequent shallow slow slip events occur.

Alaska‐Yukon Glacier Depths From a Decade of Airborne Radar Sounding

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract NASA's Operation IceBridge employed airborne radar sounders in Alaska and adjacent northwestern Canada between 2012 and 2021 to measure the thickness of the region's glaciers. Here we present the first comprehensive analysis of these data, analyzing ∼31,700 linear‐km of radar profile data to provide over 5,500 linear‐km of ice thickness and ...

Reconstructing the Exhumation and Paleo‐Earthquake History of a Submarine Normal Fault From Preserved Markers at the Seafloor (Roseau Fault, Lesser Antilles, France)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Assessing seismic and tsunami hazards along coastlines requires understanding past earthquakes and their recurrence along active submarine faults. Subaqueous paleoseismology commonly relies on sediment cores and seismic reflection data, but these methods may be limited by local site conditions or data quality.

Subduction Parameters Controlling the Occurrence of Shallow and Deep Slow‐Slip Events (SSEs)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Slow‐slip events (SSEs) are transient aseismic fault‐slip phenomena that release tectonic stresses in a variety of tectonic environments, including subduction zones. In subduction margins, SSEs commonly occur along the plate interface at shallow (<20 km) and deep (30–60 km) depths.

Linking megathrust earthquakes to brittle deformation in a fossil accretionary complex [PDF]

Nature Communications, 2015
AbstractSeismological data from recent subduction earthquakes suggest that megathrust earthquakes induce transient stress changes in the upper plate that shift accretionary wedges into an unstable state. These stress changes have, however, never been linked to geological structures preserved in fossil accretionary complexes.

Outer rise seismicity boosted by the Maule 2010 M-w 8.8 megathrust earthquake [PDF]

, 2015
Artículo de publicación ISIThe Maule 2010 megathrust earthquake M-w 8.8 has been characterized by two coseismic high-slip patches (asperities) north and south of the epicenter, separated by a region of lower slip. Here, we invert full broadband waveforms

GLOBAL TREND OF MEGATHRUST RESEARCH IN THE LAST TEN YEARS [PDF]

Science of Tsunami Hazards, 2022
Megathrusts have been the subject of more research recently. Therefore efforts are needed to understand the patterns, novelties, research trends, and potential future research areas connected to megathrusts.
