Fluvial geomorphic parameters of the Shuiluo River Catchment and their tectonic implications, SE Tibetan Plateau

Progress in Earth and Planetary Science
The Shuiluo River Catchment (SRC) is the front zone of the southeast compression and uplift of the Tibetan Plateau, with intense tectonic activity. In the basin, a series of regional large NW–SE trending active faults are developed.

Comparative geospatial and statistical analysis of DEM-derived geomorphic indices from multiple datasets for assessing relative active tectonics

Geomatics, Natural Hazards & Risk
Tectonic activity plays a vital role in achieving sustainable land management and hazard mitigation in seismically active regions. This study evaluates geomorphic indices derived from four digital elevation models (DEMs), including SRTM, Copernicus, FAB,

Unveiling spatial heterogeneity in urban underground space development patterns and mechanisms for differentiated planning: A points of interest‐based study of Shanghai

Deep Underground Science and Engineering, EarlyView.
This study investigated the spatial patterns and development mechanisms of urban underground space (UUS) in Shanghai using underground points of interest data. It revealed distinct development mechanisms between the main city and suburbs, highlighting the need for differentiated UUS planning and policies to optimize underground space resources ...

Evaluation of relative tectonic activity along the Priene-Sazl Fault

, 2019
The West Anatolia Extensional Zone, which has a width of about 300 km, is located within the Alpine-Himalayan belt and is one of the regions with intense seismic activity in the world. The most important geomorphological structures in this area are three main graben structures resulting from regional N-S extension since the Early Miocene.

Relative Assessment of Tectonic Activities, Upper Kangir Basin (Eyvanegharb) UsingGeomorphic Indicators

جغرافیا و آمایش شهری منطقه‌ای, 2013
طی سال‌های اخیر محققان مختلف سعی در کمّی نمودن حرکت‌های زمین‌ساختی داشته و شاخص‌های متعددی را با عنوان شاخص‌های ژئومورفیک ارایه نموده‌اند. استفاده از این شاخص‌‌ها، امکان تحلیل مناسب از وضعیت تحول شبکۀ زهکشی و تغییرات جبهۀ کوهستان بر اثر فعالیت‌های زمین‌ساختی را فراهم می‌کند.

Dynamic cracking properties and generating conditions of coal under rapid gas release

Deep Underground Science and Engineering, EarlyView.
Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.
