Analysis of seismic noise in the Romanian-Bulgarian cross-border region
Journal of Seismology - Tập 22 - Trang 1275-1292 - 2018
We present the first detailed investigation of the background seismic noise recorded in the Romanian-Bulgarian cross-border region over 3 years (2012–2015). We used the power spectral densities probability density functions (PSD PDFs) to study the noise variations in the period domain (0.025–1 s) as well as in the secondary microseism band (2–10 s). Strong diurnal variations and an increase of the......
New constraints on lithospheric thickness of the Iranian plateau using converted waves
Journal of Seismology - Tập 17 - Trang 883-895 - 2013
The study of mantle lithosphere plays a key role to reveal predominant tectonic setting process of a region. The current geological and tectonic setting of Iran is due to the ongoing continental–continental collision of the Arabian and Eurasian plates. We applied a combined P and S receiver function analysis to the teleseismic data of nine permanent broadband seismic stations of the International ......

Adaptation of P-wave moment magnitude of Turkey’s earthquakes for early warning purpose
Journal of Seismology - Tập 26 - Trang 243-263 - 2022
The determination of an earthquake’s magnitude correctly is vital to understand the situation and prevent loss of lives and planning first organization for the rescue with early warning/tsunami warning at a region. In this study, we calculated moment magnitude using a P-wave portion of seismic records and indicated that it is possible to use it with all available seismic data recorded at local and......
The comparison of macroseismic intensity scales
Journal of Seismology - Tập 14 - Trang 413-428 - 2009
The number of different macroseismic scales that have been used to express earthquake shaking in the course of the last 200 years is not known; it may reach three figures. The number of important scales that have been widely adopted is much smaller, perhaps about eight, not counting minor variants. Where data sets exist that are expressed in different scales, it is often necessary to establish som......
Statistical estimation of maximum peak ground acceleration at a given point of a seismic region
Journal of Seismology - Tập 1 - Trang 395-405 - 1997
A straightforward procedure is suggested for statistical estimation of maximum peak ground acceleration, Amax (T), that will occur at a given point of a seismic region in future time period T. This procedure is based on the Bayesian approach and includes estimation of three unknown parameters;b, the slope of acceleration-frequency law; α, the maximum regression acceleration; λ, the rate of signifi......
The unified catalogue of earthquakes in central, northern, and northwestern Europe (CENEC)—updated and expanded to the last millennium
Journal of Seismology - Tập 13 - Trang 517-541 - 2009
New databases motivate improvements and extensions of the catalogue by Grünthal and Wahlström (J Seismol 7:507–531, 2003a) – G&W03 – of earthquakes in central, northern, and northwestern Europe with M
w ≥ 3.50. Data from over 30 regional catalogues, the International Seismological Centre and U.S. National Earthquake Information Center bulletins for the NE Atlantic Ocean, an......
Comment on “Slowness-azimuth corrections of teleseismic events for IMS primary arrays in China” by Hao and Zheng
Journal of Seismology - Tập 15 - Trang 653-658 - 2011
Knowledge about backazimuth and slowness deviations at seismic arrays can be used as a tool to study subsurface lateral heterogeneity and improve the ability to locate events. Recently, Hao and Zheng (J Seismol 13:437–448, 2009) estimated the backazimuth and slowness deviations for teleseismic P waves recorded by the HILR array and the LZDM array using f–k analysis. They attributed the significant......
Probabilistic inversion of Rayleigh-wave dispersion data: an application to Mt. Etna, Italy
Journal of Seismology - Tập 17 - Trang 335-346 - 2012
We present a methodology for determining the elastic properties of the shallow crust from inversion of surface wave dispersion characteristics through a fully nonlinear procedure. Using volcanic tremor data recorded by a small-aperture seismic array on Mount Etna, we measured the surface waves dispersion curves with the multiple signal classification technique. The large number of measurements all......
