State-of-the-Art Seismic Studies of Loess Tunnels in China

Advances in Civil Engineering
Large earthquakes occur frequently around the world. Due to the fragility of loess, the effects of seismic events on loess tunnel projects have received considerable in-depth research attention.

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.

Tectonics, geology and origins of Te Riu‐a‐Māui / Zealandia

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 531-567, December 2025.
ABSTRACT Te Riu‐a‐Māui / Zealandia is a 95% submerged, five million square km southern hemisphere continent that includes the islands of New Zealand and New Caledonia. For the last 45 million years (Ma) Zealandia has been cut by the Pacific‐Australian plate boundary which today changes character from a west‐dipping subduction zone in the north to ...

Hazard assessment of seismic-collapsed loess landslides on the Loess Plateau as exemplified by the M6.2 earthquake in Jishishan County, China

Frontiers in Earth Science
The Loess Plateau is marked by intense neotectonic activity and frequent earthquakes. Its unique physico-mechanical properties, combined with the granular overhead pore structure of loess, render it prone to seismic landslides triggered by strong earthquakes.

Geospatial Insights Into Landslide Relics in the Northern Half of the Taihang Mountains: Topography, Geology and Beyond

Geoscience Data Journal, Volume 12, Issue 4, October 2025.
Landslides in the northern Taihang Mountains are concentrated at elevations of 800–1300 m, on slopes over 45°, and in north‐ and northwest‐facing aspects. Proximity to rivers increases landslide frequency, whereas faults influence landslide size. Loess deposits, grasslands and forests exhibit high landslide occurrence, with barrens showing the densest ...

Rupture of the 1949 Khait Earthquake on a Cryptic Fault: Implications for Earthquake Hazard

Tectonics, Volume 44, Issue 10, October 2025.
Abstract The 1949 Mw 7.6 Khait earthquake, Tajikistan, was one of the most destructive of the Pamir—Tien Shan region, killing over 7,000 people by building collapse and landsliding. It occurred at the transition between the Pamir and Tien Shan mountain ranges, which converge along the narrow Vashkh river valley.

Large Surface‐Rupturing Earthquakes and a >12 kyr, Open Interseismic Interval on the Tintina Fault, Yukon

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract We present the first geomorphic evidence for successive, surface‐rupturing earthquakes throughout the Quaternary on the Tintina fault in the Yukon Territory, northwestern Canada. A ∼130‐km‐long series of scarps and pressure ridges offset 2.6 Ma and 132 ka landforms by ∼500–1,500 m and 65–85 m, respectively, indicating a dextral slip rate of ∼0.
