Google Earth images in the Marche Region of Central Italy revealed a circular structure consisting of a ring system made up of concentric hills and valleys. Cartography, DEM, geological, and available geophysical data were used to constrain the possible origin of the structure. Located in the Messinian foredeep deposits of the Central Apennines, it has a rim diameter of 3.75 km and a central uplift connected to its southernmost part. As it was formed in the clays of the Lower Pliocene, and clays are believed to have emerged definitively after the Upper Pliocene, its age might be constrained to the Lower Pleistocene. Similar concentric structures are usually found in impact craters, sedimentary domes, and volcanic landforms. As salt domes and magmatic activity are not found in this region, this study seeks to validate the results of previous work that it was the result of an ancient impact crater of hydrological, brachyanticline, or clayey diapiric origins. Specifically, an observed second ring portion with a curvature radius about double the first in size will be investigated in this work. This second ring portion appears to be concentric to the first one and is visible along its northern and western parts. Although double concentric rings are usually due to impact craters, the absence of the ring portion in the other two directions and the probable deviation of a river, deduced by studying hydrography, support the hypothesis that it might be of clay diapir origin.
The architecture and engineering industry employs resource-efficient sustainable building design (SBDC) to reduce greenhouse gas emissions and mitigate environmental damage. This study examines the understanding and practice of SBDC among Chinese architecture students. A survey of 555 undergraduates from China’s architecture universities was conducted. Two independent and seven dependent variables were analyzed to evaluate the impact of academic stages and practical experiences on students’ awareness. The findings reveal that over 70% of respondents consider SBDC important in architecture. More than half have taken courses with over 30% SBDC content. However, 45.85% of respondents only have a basic understanding of SBDC. This result underscores the significance of educational disparities, this insufficiency is likely due to inadequate coverage and representation of SBDC in the curriculum. Our study highlights the necessity of enhancing SBDC-related education within the current curriculum framework to ensure all students receive a systematic and comprehensive knowledge of sustainable building design.
