Summary: This study investigates the seismic effects of ancient anthropogenic cavities in Chieti city center in Italy through the cavity amplification factor (CAF). The results show that CAF values are only significant in the period range of 0.1-0.5 seconds and vary from 1% to 15%. The maximum CAF is felt away from the cavity axis at a distance equal to about 1.5 times the cavity width. The study also demonstrates how to draw CAF maps for microzoning purposes using the case study of Chieti city center.

Summary: This study presents the first seismic reflection images of the Paganica and Bazzano basins, which are tectonic basins developed in the hanging wall of the Paganica-San Demetrio Fault System. High-resolution seismic profiles were acquired to reveal the structure of the basins and the uppermost splays of the 2009 earthquake. The seismic data provide fine details of the subsurface stratigraphic setting and reveal previously unknown conjugate normal faults.

Summary: This study evaluates the amplification factors of a tuff cliff under seismic loading using 1D and 2D modeling. Field measurements and laboratory tests were conducted to estimate the geotechnical and geophysical parameters for the analysis. The results showed that the amplification factor reached a maximum value of 10 with a period of 0.11 s in the cliff edge area, and decreased to 2.90 seaside and 4.0 landside in other areas. The comparison between 1D and 2D modeling highlighted the importance of topographic effects related to the cliff.

Summary: In some geological settings, deeper layers can significantly amplify ground motion during earthquakes, especially at low frequencies. Indirect geophysical exploration techniques are suitable for accurately quantifying the influence of deeper geology on seismic ground motion, as they can provide realistic representations of subsoil structure at various depths. This study focuses on acquiring and processing combined shear- and compressional-wave seismic reflection data to obtain a reliable geological/geophysical model with accurate seismic velocities. It demonstrates the advantages of reflection seismic prospecting for characterizing soft-sediment basins and improving knowledge of the geological structure of the study area.

Summary: This study presents the geological hazards in the densely populated Campi Flegrei volcanic area in southern Italy. Volcanic and seismic activities, combined with landslides, floods, and coastal erosion, have significantly influenced the landscape of this region. The research data reveals that landslides are most frequent along the coastline and western-facing inland slopes. The frequency of deadly events has decreased since the early 1980s, indicating a reduced risk to the population in the Campi Flegrei caldera.

Summary: Nowadays, development projects are happening rapidly in many developing countries. This study focuses on the Cairo-Suez District in Egypt, which is an important area for infrastructure projects and urbanization. It is crucial to reduce the risks of natural disasters in this area, so information supporting geo-environmental hazards assessment is needed. The Gabal Ataqa area is significant for its socioeconomic importance as an industrial zone in a national project. The study utilizes seismic reflection to detect faults and subsurface features in this area. Based on the results, it is recommended to relocate the industrial zone away from the identified faults.

Summary: This study reveals that land seismic data in complex areas exhibit weak and distorted prestack reflections with low coherency. The researchers explain this phenomenon by introducing multiplicative random noise, represented by random timeshifts and random phase perturbations. They speculate that these multiplicative distortions can be attributed to near-surface scattering layers with small-to-medium-scale geologic heterogeneities. The findings of this study also provide theoretical justification for previously proposed methods of addressing random multiplicative noise in seismic processing.

Summary: Through seismic noise analysis, we found significant effects of water storage changes on velocity variations after water reinjection at the Val d'Agri oil field. After removing the effect of hydrological variations, a decrease in relative velocity was observed. The diffusivity values and delay time of small seismic events were found to be compatible.

Summary: The Caronia area in northeastern Sicily, Italy, has been the focus of attention due to landslides causing economic damage and loss of productive activities. The site's heterogeneity makes it susceptible to seismic topographic amplification effects, leading to numerical studies and seismic effect evaluations being conducted to assess the slope affected by landslides. Geological and geotechnical characterizations, as well as local seismic response analyses, were carried out to understand the site's seismic behavior.

Summary: The paper presents observations from a 2007 experiment along the southwestern coast of Sicily, focusing on the phenomenon of marrobbio, a type of meteotsunami commonly seen in the Strait of Sicily. The study found rapid air pressure and sea level oscillations during marrobbio events, with atmospheric disturbances propagating mostly towards east-northeast at speeds of 19-24 m/s. The atmospheric patterns were conducive for wave ducting mechanisms during most marrobbio events, highlighting the need for long-term high-frequency observations and high-resolution models to quantify meteotsunamis accurately.

Summary: This article discusses a potential multi-hazard scenario resulting from an earthquake in the highly seismogenic area of the Mediterranean Sea, Augusta Bay. The bay is heavily contaminated with mercury due to long-term industrial exploitation. Utilizing a high-resolution hydrodynamic and transport model, the article calculates the enhanced spreading of mercury in the open sea following the damage to an artificial damming system. The simulated scenario highlights the need for a reevaluation of risk management in marine areas with significant contamination.

Summary: This paper focuses on providing field evidence of the environmental hazards associated with flood events in highly contaminated marine coastal areas. Using sediment cores from the Crotone site in the Ionian Sea, the study examines the distribution of heavy metals and their potential as long-term sources of pollution for the marine ecosystem. The results show that historically flash flood events played a crucial role in transferring highly polluted sediments from land to sea, leading to secondary contamination in offshore areas. This study highlights the cumulative mechanisms of multiple pollution and transfer of contamination in coastal and offshore environments.

Summary: This study investigates the extent of human-induced physical impacts on the continental shelf near Augusta Bay in southeastern Sicily, Italy. Using various techniques and direct seabed samplings, the researchers identified several anthropogenic footprints, such as anchor grooves, excavations, and trawl marks, on the seafloor. Furthermore, the long-term disposal of dredge spoils has altered the seafloor morphology, creating a thick deposit on the central continental shelf. The production of a thematic map of seafloor features offers valuable insights into sediment facies distribution and the localization of human disturbance.
