On the Time Indices in the Geomorphic Histories of the Coastal Sand Dunes

open access: yesThe Quaternary Research (Daiyonki-Kenkyu), 1975
Many coastal sand dunes are distributed along the present strand-line of Japan. The ages of formations of those sand dunes can be classified into three types, as the Pleistocene sand dunes, “Older”and“Younger”Dunes in Holocene.The Older Dunes in Holocene were formed during the stage of the highest sea level in the Flandrian transgression, which was ...

Glacier Equilibrium‐Line Altitude Change Across Alaska and Adjacent Canada Indicates a Cold, Dry Little Ice Age and Weaker Aleutian Low

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract As Arctic warming accelerates, understanding hydroclimate shifts is key to projecting glacier melt and sea‐level rise. We assess the climatic signature of the Little Ice Age (LIA; ∼1250 to 1900) by quantifying changes in equilibrium‐line altitude (ΔELA) for 215 Alaskan glaciers from the LIA maximum to present (2016–2024), using remote sensing ...

Relative Uplift Rates Along the Central Mindoro Fault, Philippines

open access: yesGeoHazards
The Central Mindoro Fault (CMF) is a major active oblique, sinistral strike-slip fault within the Philippine archipelago that accommodates the oblique convergence between the Philippine Sea Plate (PSP) and the Sunda Plate (SP).

Geomorphic indices for unveiling fault segmentation and tectono-geomorphic evolution with insights into the impact of inherited topography, Ulsan Fault Zone, Korea

open access: yes
Abstract. Quantifying present topography can provide insights into landscape evolution and its controls, as the present topography is a cumulative expression of the types, distributions, and intensities of past and present processes. The Ulsan Fault Zone (UFZ) is an active fault zone on the southeastern Korean Peninsula that has been reactivated as a ...
