Homogeneous magnitude system of the eurasian continent
Tectonophysics, 1978In spite of the great efforts of seismologists to develop the magnitude to one of the basic earthquake parameters with a clear physical significance, serious discrepancies appeared in both the individual station estimations and the mean values, given by different networks of stations and international agencies, for seismic waves of different types, and

On a homogeneous system of selected Eurasian stations for magnitude determinations
pure and applied geophysics, 1974After a special investigation into the stability of seismic stations of the Eurasian continent, a system of reference stations for routine determination of earthquake magnitudes has been selected. A method for determining station corrections in a network of continental dimensions has been developed and tested for PV waves observed by eight Eurasian ...

Journal of African Earth Sciences, 2021
Abstract New MW–ML magnitude relations valid for the periods January 1971–March 1997, April 1997–September 2012 and October 2012–present are presented for South Africa. Three MW–ML relations were derived for the respective periods by applying a general orthogonal regression using 85 mining-related and tectonic events.

Magnitude calibrating functions for a multidimensional homogeneous system of reference stations
Tectonophysics, 1985Abstract Calibrating functions play a substantial role in the determination of earthquake magnitudes. Their shape and character is closely connected with the internal structure of the Earth, the distribution of velocities and attenuation of seismic waves in the Earth's body.

Homogeneous magnitude system with unified level for usage in seismological practice
Studia Geophysica et Geodaetica, 1991A homogeneous magnitude system (HMS) for determining comparable magnitudes of shallow earthquakes was established and tested on the basis of several thousands of observations of 32 Eurasian seismic stations for seven different wave types. The magnitude level of the HMS was fixed by the level of LH-wave magnitudes, which allows us to maintain the ...

A Catalog of Taiwan Earthquakes (1900-2006) with Homogenized Mw Magnitudes
Bulletin of the Seismological Society of America, 2008Taiwan has a relatively complete catalog of earthquakes since the first seismograph was installed in 1897. However, due to changes in seismographic characteristics, network coverage, and observational practice, the definition and procedure for magnitude determination were different during different time periods.

A complete and homogeneous magnitude earthquake catalogue of Iraq
Arabian Journal of Geosciences, 2013A complete and homogeneous magnitude earthquake catalogue spanning the period 1900 to 2010 was created. The catalogue covers the area 29° to 37.5° N and 39° to 48° E. Entries in the new earthquake catalogue were cross checked and additions made from various sources of earthquake records to ensure that repetitions are not included in this analysis ...

Homogenization in Terms of Mw of Local Magnitudes of Italian Earthquakes That Occurred before 1981
Bulletin of the Seismological Society of America, 2017In the last two decades, several studies addressed the revaluation and homogenization of the Italian instrumental seismic catalog, but all of them refer to the time interval from 1981, that is, the starting year of the Catalogo Strumentale dei Terremoti Italiani (CSTI).

International Journal of Structural Stability and Dynamics, 2020
This paper investigates the dynamic properties of an inhomogeneous, Bernoulli–Euler multi-segment beam composed of different materials. To the best of knowledge of the authors, the problem of random vibrations of beams composing of different chunks of the beams, namely, strong and weak parts, has not been studied in the literature. In this paper, exact
