“…The great amount of data and the good coverage over the study area allow also to propose a reference noise model for Italy. Optimized regional models have been often proposed since they provide better representation with respect the most popular global models (Custódio et al, 2014;Demuth et al, 2016;Diaz et al, 2010;Evangelidis & Melis, 2012;Hafiez & Toni, 2019;Ozyazicioglu et al, 2020;Rastin et al, 2012;Sevim et al, 2018).…”

“…During the last decade, the approach became one of the valuable applied methods in Egypt for site characterization. The technique was applied by many investigators (Mohamed and Fat-Helbary, 2010;Mohamed et al, 2013Mohamed et al, , 2015Mohamed et al, , 2020Mohamed et al, , 2021aMohamed et al, , 2021bAbdel-Hafiez and Toni, 2019;Abudeif et al, 2019;Fat-Helbary et al, 2019;Meneisy et al, 2020) in many new and important projects across the Egyptian teritories and gave good and acceptable results.…”

The Kima area is located in the southeastern part of Aswan city where the Aswan wastewater treatment plant and one of the giant factories in the Middle East for chemical and fertilization. The area is very close to the main active seismic zone in South Egypt, where November 7, 2010 earthquake (M 4.6( occurred. The earthquake was felt strongly and caused minor damage (cracks) to different buildings in the Kima area. This earthquake motivates us to perform the current study for earthquake disaster mitigation in this area. The main target of the study is the evaluation of the local soil conditions based on Multichannel Analysis of Surface Waves and Horizontal to Vertical Spectral Ratio seismic techniques. The outputs results include different parameters (Vs30, the resonance frequency, the amplification factor, and the NEHRP site classification). The predominant NEHRP site class is class D occupying the middle part of the Kima area. The resonance frequency ranged from 0.62 to 13.8 Hz over all the investigated areas and has a small range close to the factory site (0.62–0.78 Hz).

“…Signal processing followed McNamara and Buland′s approach for noise studies [6], and the PQLX software (PASSCAL Quick Look eXtended) [7] was employed for noise power quantification and calculation of noise probability density for different band frequencies. Other researchers in earlier noise studies for regional and global networks [8][9][10][11][12][13] have successfully used this method to estimate ambient seismic noise. Therefore, this signal processing method is considered most suitable for this study.…”

This paper analyses seismic noise from broadband seismic stations within the Cuban National Seismic Service, focusing on location sites, soil or rock quality at installation sites and the impact of various factors on the noise signature of these seismic stations. A brief technical description of deployed equipment is provided and the methodology for data selection and analysis is presented.The study provides annual performance assessment for each station, considering specific details for each particular case. Likewise, the effect of diurnal/nocturnal and seasonal variations on noise power spectral density (PSD) is analyzed. In addition, plotted graphs show the relationship between the occurrence of extreme weather events, such as hurricanes and cold fronts through Cuban eastern and western regions, respectively, and the increase of noise level, specifically for marine microseisms period band. Finally, the influence of instrumental variations in noise level of seismic stations is characterized.
