Published: Jan. 28, 2025

Abstract The earthquake sequence that occurred on February 6, 2023, centered in Türkiye caused extensive loss of life and significant damage. In this study, the geotechnical properties central districts Malatya province, one provinces affected by these earthquakes, were calculated using data obtained. calculations, correlations suggested Turkish Building Earthquake Code (TBEC) internationally recommended used. Thus, difference between methods proposed TBEC was interpreted. Using 1890 drilling data, 1765 seismic 1764 microtremor calculations made to determine bearing capacity values for 3 m x pad foundation, liquefaction potentials soil classifications around region. results obtained from mapped with geographical information systems-based software. Results study revealed 2.9% area Battalgazi district 1.71% Yeşilyurt had potential. Almost 80% each found have a class ZD (medium dense gravel sand or clay layers) according TBEC. findings compared previous studies, satellite images post-earthquake observations. areas where damage observed intensively, relatively low. It concluded building poor conditions poses profoundly serious risk terms earthquakes very precautions should be taken gathering several disciplines during construction structures.

This article explores the impacts of climate change on rural and natural landscapes in region Eastern Macedonia Thrace, northeastern Greece. The spatial distributions bioclimatic de Martonne Index phytoclimatic Emberger were calculated at a very high resolution (~500 m) for present conditions (1970–2000), two future time periods (2030–2060; 2070–2100), greenhouse gas concentration scenarios (RCP4.5; RCP8.5). results show significant changes, especially Rhodope Mountain range along almost whole length Greek–Bulgarian border, where forests ecosystem value are located, together with areas Evros river valley, as well coastal zone Aegean Sea. describes processes changes that can significantly modify study area’s landscapes. area reveals shift toward xerothermic environments over time, projected under extreme RCP8.5 scenario. By 2100, projections indicate around 40% agricultural eastern, southern, western regions will face Mediterranean semi-humid conditions, requiring supplemental irrigation sustainability. predicts approximately 42% experience sub-humid mild or cool winters. In comparison, 5% drier humid/sub-humid, warm winter conditions. These foreseen futures propose initial interpretations key landscape conservation, capital, services management.

Nature-based Natural-hazard Preparedness: A Cross Section of Categorized Examples

Journal of Environmental & Earth Sciences, Journal Year: 2024, Volume and Issue: 6(1), P. 33 - 44

Published: March 1, 2024

Despite prevailing interests, no rigorous research has been conducted to examine the role of nature in natural-hazard preparedness. This systematic review aimed describe how can reduce impacts natural hazards during preparedness stage. The study focuses on land, water, and air systems three types stakeholders: international organizations, developed countries, developing countries. Further, it provides supplementary strategies, such as immediate actions, local engagement, development, that stakeholders should apply enhance their nature-based We suggest integrating costs benefits analysis, culture, societal challenges, environmental justice into implementation solutions. Finally, this outlines framework by discussing relationship between society.

Predictive capabilities, robustness and limitations of two event-based approaches for lag time estimation in heterogeneous watersheds

Journal of Hydrology, Journal Year: 2024, Volume and Issue: 642, P. 131814 - 131814

Several studies have demonstrated that response times in natural catchments decrease with increasing rainfall intensity. Consequently, event-based estimations of catchment are paramount importance applied hydrology. Specifically, they the potential to address a major inconsistency use empirical formulas. These formulas often assume as constant parameters, regardless whether extreme or frequent flood events considered, thus neglecting role flow velocities. In this paper, built upon previous approaches developed and/or analyzed by authors, two different recent methods for critically reviewed, and their predictive performances compared. First, four "physically-based" formulas, calibrated using synthetic rainfalls three small Italian watersheds reproduce results two-dimensional hydrodynamic-based rainfall/runoff model and, consequently, simulated wave celerities, considered. Then, detrending moving-average cross-correlation analysis (DMCA) has been assess average time elapsed between centroids precipitation discharge series. The soundness these is initially assessed based on ability estimated lag from observations. Their robustness further evaluated analyzing magnitude basin scale dependence inferred velocities compared observed values, following approach proposed literature. issues discussed reference 60 rainfall-runoff occurring across 27 Hungary Italy, which possess substantially geomorphic climatic features, highlighting both need improvements. Both give error rates around 37% dataset.
