Influence of Structural Maturity on the Rupture Morphology of the Northern Alpine Fault, Aotearoa New Zealand

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine Fault (AF) in Aotearoa New Zealand is a fast‐slipping plate boundary fault late in its seismic cycle that presents a major source of seismic hazard. Past earthquakes have created a structural‐geomorphic record of surface ruptures that we map and analyze for the northern AF using 1,000 km2 ${\text{km}}^{2}$ of Light Detection and ...

Do Large Earthquakes Occur at Regular Intervals Through Time? A Perspective From the Geologic Record

Geophysical Research Letters, 2019
We analyzed a catalog of 31 published earthquake chronologies to assess the commonality of quasiperiodic earthquake recurrence across a range of fault types and tectonic settings.

Impact of Anaerobic Cold Storage on Subseafloor Microbial Communities

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Sediment cores recovered from the deep sea often cannot be sampled for microbiological analysis immediately due to the need for core splitting and processing for subsequent onboard measurements and core storage. Consequently, sections are often stored at 4°C under anaerobic conditions for extended periods.

Paleoseismic trenching on slip-partitioned surface ruptures associated with the 2016 Kumamoto earthquake

Seismica
Surface ruptures appear over a wide area in addition to the primary fault during a Large earthquake like the 2016 Kumamoto earthquake. Although the displacement of such distributed surface ruptures is small, information on their paleo activities provides

Implications of some early Jewish sources for estimates of earthquake hazardin the Holy Land

Annals of Geophysics, 2004
For the past two millennia the Holy Land was under the yoke of successive invaders and oppressors, not a fertile ground for growth of historiographic traditions.

New Zealand Active Faults Database: the high‐resolution dataset v2.0

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 955-970, December 2025.
ABSTRACT The New Zealand Active Faults Database (NZAFD) contains underpinning data to help mitigate the impacts of future surface‐rupturing earthquakes in Aotearoa New Zealand. However, defining the associated hazards and risks must be undertaken at relevant scales and as such, the NZAFD contains two scale‐based datasets each serving complementary, but

The Manyas fault zone (southern Marmara region, NW Turkey): active tectonics and paleoseismology

Geodinamica Acta, 2017
The Manyas fault zone (MFZ) is a splay fault of the Yenice Gönen Fault, which is located on the southern branch of the North Anatolian Fault System. The MFZ is a 38 km long, WNW–ESE-trending and normal fault zone comprised of three en-echelon segments ...

Paleoseismology related to deformed archaeological remains in the Fucino Plain. Implications for subrecent seismicity in Central Italy

Annals of Geophysics, 1996
During paleoseismological investigations on the seismogenic structure responsible for the 1915 earthquake in the Fucino Plain (Central Italy), some trenches were excavated at the intersection between Roman-age channels and a fault characterized by ...

Application of Tree-Ring Analysis to Paleoseismology [PDF]

Reviews of Geophysics, 1997
Knowledge of a region's seismicity is one of the keys to estimating earthquake hazards. Unfortunately, historical records are generally inadequate for evaluations of seismicity. Paleoseismology addresses this problem using various techniques for dating earthquake‐disturbed materials.

Insights into temporal earthquake clustering from the Settlement Fault, southeastern Otago, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 747-772, December 2025.
ABSTRACT We combine previous studies, fieldwork, lidar data, and trenching to examine late Quaternary activity of the SE‐dipping ≥23 km long Settlement Fault in the southeastern South Island. Trenching of a scarp crossing a small alluvial fan exposed a > 3 m thick sequence of folded sandy to silty fan alluvium.
