In Search for the Limit Between Sedimentology and Stratigraphy: The Case of Zanclean and Gelasian Shallow-Marine Deposits of the Crotone Basin, Southern Italy
The integration of sedimentological and micropaleontological data in the Zanclean and Gelasian shallow-marine deposits of the Crotone Basin (southern Italy) has allowed documentation of meter-to-decameter-scale high-frequency sequences bounded by wave-ravinement surfaces (WRSs), which in turn are…

A Thermodynamic Closure Model for Titan’s Surface Temperature: Its Long-Term Stability Anchored to Methane’s Triple Point
We develop a minimal thermodynamic model to predict Titan’s surface temperature based on radiative–convective equilibrium and the principle of maximum entropy production (MEP). The model retains only the essential atmospheric constituents: gaseous methane, which absorbs both longwave and…

Evaluating Catchment-Scale Physically Based Modeling of Sediment Deposition During an Extreme Rainfall Event
Extreme rainfall events often trigger landslides, debris flows, and sediment-laden floods that cause severe damage in built-up areas, yet sediment deposition is rarely quantified in hazard assessments. This study evaluates the capability of the physically based catchment model LISEMHazard to…

Manifestations of the 2023 Al Haouz Earthquake as Geoheritage: Geological Processes, Landscape Impacts, and Implications for Geoconservation in the Moroccan High Atlas
The 2023 Al Haouz earthquake (Mw 6.7–6.9) is the strongest quake ever recorded in modern Morocco and ranks among North Africa’s most significant seismic events of the century. It struck the High Atlas region, causing widespread land changes, thousands of landslides, destruction in remote mountain…

Uppermost Crustal Anisotropy in the Eastern Cordillera of Colombia: Implications for Geothermal Exploration
The Eastern Cordillera of the Colombian Andes is a high-elevation asymmetric plateau subjected to NW–SE shortening. An interesting aspect of this plateau is the presence of high geothermal gradients (up to 52 °C/km), constrained by wells drilled in sedimentary basins. Radial and transverse receiver…

How Urban Activities Respond to Air Pollution: A Multi-Source Geospatial Data Analysis Records
Conventional wisdom posits that smog suppresses outdoor activity while shifting peoples’ activities indoors. Using anonymized Mobile Phone Data Provider Records fused with Point-of-Interest (POI) data sourced from the Gaode (Amap) open database for Beijing (2–22 February 2015), we test this…

Rock Engineering Knowledge and Radical Uncertainty: From Empirical Methods to Professional Practice
It is important for the rock engineering practice to acknowledge the difference between uncertainty, which diminishes with adequate data access, and radical uncertainty, which persists because critical features and failure mechanisms may remain undetected, not because of inadequate sampling but…
