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.

Deeper snow increases the net soil organic carbon accrual rate in moist acidic tussock tundra: 210Pb evidence from Arctic Alaska

Arctic, Antarctic, and Alpine Research, 2020
The net change in the carbon inventory of arctic tundra remains uncertain as global warming leads to shifts in arctic water and carbon cycles. To better understand the response of arctic tundra carbon to changes in winter precipitation amount, we ...

Contrasting Behaviors of 210Pb and 210Po in the Productive Shelf Water Versus the Oligotrophic Water

Frontiers in Marine Science, 2021
We measured the total, truly dissolved (<10 kDa), colloidal (10 kDa–0.2 μm), and particulate phases (>0.2 μm) of 210Pb and 210Po in the East China Sea (ECS) shelf water and the East Sea (Japan Sea).

Sedimentary record of submarine gravity‐flow events in the southern Ryukyu forearc during the last 200 000 years: Archive of mega‐earthquakes and tsunamis

Sedimentology, Volume 72, Issue 7, Page 2323-2360, December 2025.
ABSTRACT Despite high convergence velocity, the southern Ryukyu subduction has relatively low and sparse instrumental seismicity, in contrast with the Yaeyama Islands, hit by huge tsunamis over the last few thousand years. This study explores the potential of deep marine sediments to record past large earthquakes and tsunamis.

A multi-year study of radioactivity in surface air and its relation to climate variables in Belgrade, Serbia [PDF]

Nuclear Technology and Radiation Protection, 2013
Activities of 7Be and 210Pb were monitored in surface air in Belgrade, Serbia, from 2004 to 2012. The measurements were taken from two locations, in an open field of a city suburb and in the central city area.

7Be Solar Neutrino Measurement with KamLAND [PDF]

, 2015
We report a measurement of the neutrino-electron elastic scattering rate of 862 keV 7Be solar neutrinos based on a 165.4 kton-day exposure of KamLAND. The observed rate is 582 +/- 90 (kton-day)^-1, which corresponds to a 862 keV 7Be solar neutrino flux ...

Flood‐Driven Turbidite Deposition in a Highstand‐Detached Submarine Canyon

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Turbidites on active margins represent key archives of great earthquakes, yet turbidity currents triggered by non‐seismic events complicate paleoearthquake records and influence geochemical budgets. Sediment cores collected from highstand‐detached Astoria Canyon address whether non‐seismic turbidity currents are preserved in canyon ...

Estimation of 210Po and 210Pb and its doses to human beings due to consumption of freshwater species of Ponnusamuthiram Lake, South India

Radiation Protection and Environment
A systemic study on the natural radionuclides such as 210Po and 210Pb in the environmental matrices and biota of Ponnusamuthiram Lake (Kumarapalayam) has been undertaken to establish a baseline data on the radiation profile of Ponnusamuthiram Lake ...

Untangling sedimentation processes in a deep fjord lake in Labrador: A high‐resolution archive of past environment dynamics at Grand Lake

The Depositional Record, Volume 11, Issue 5, Page 1259-1284, November 2025.
Sedimentological and geochemical characteristics are used to reconstruct sedimentation dynamics and erosional processes. Several rapidly deposited layers are characterised over changing depositional environments during the Late Holocene, from a phase when the lake was connected to the sea to a more stable state conducive to varve formation.
