Two-step seismic noise reduction caused by COVID-19 induced reduction in social activity in metropolitan Tokyo, Japan [PDF]
Earth, Planets and Space, 2020 The COVID-19 pandemic that started at the end of 2019 forced populations around the world to reduce social and economic activities; it is believed that this can prevent the spread of the disease.

Low-Frequency Seismic Noise Properties in the Japanese Islands. [PDF]
Entropy (Basel), 2021 The records of seismic noise in Japan for the period of 1997–2020, which includes the Tohoku seismic catastrophe on 11 March 2011, are considered. The following properties of noise are analyzed: The wavelet-based Donoho–Johnston index, the singularity ...

Spectral Characterization and Spatiotemporal Variability of the Background Seismic Noise in Italy
Earth and Space Science, 2021 In this study, we assess the spectral characteristics of seismic noise at the sites of the Italian Seismic Network and its spatio‐temporal variability. The evaluation of noise is crucial for the assessment of the detection capability of a seismic network.

Seismic hazard indicators in Japan based on seismic noise properties [PDF]
Journal of Earth and Environmental Sciences Research, 2023 The seismic noise recorded at the network of stations in Japan for more than 26 years (1997 - March 2023) is being investigated. The article is a continuation of the number of works in which the analysis was performed for 1997 - March 2021. New data for 2 years of follow-up observations, combined with a new approach to their analysis, provided ...

Global Seismic Noise Entropy [PDF]
Frontiers in Earth Science, 2020 Data of continuous records of low-frequency (periods from 2 to 1,000 min) seismic noise on a global network of 229 broadband stations located around the world for 23 years, 1997–2019, are analyzed. The daily values of the entropy of the distribution of the squares of the orthogonal wavelet coefficients are considered as an informative characteristic of

Terrae Didatica, 2019 Rainfall-induced variations in pore water pressures are the most common sources of significant disasters like landslides, dams’ failure, and other structural collapses. This study aimed at communicating preliminary results of seasonal monitoring of the Sobradinho landslide, Brasilia, Brazil, using ambient seismic noise.
