ON THE MOMENT MAGNITUDE–LOCAL MAGNITUDE CALIBRATION FOR EARTHQUAKES IN THE NORTHWESTERN CAUCASUS
Доклады Российской академии наук. Науки о Земле, 2023The spectral and dynamic parameters of the sources of regional seismic events have been studied for the territory of the Northwestern Caucasus using stations from the network of the Geophysical Survey, Russian Academy of Sciences and Crimean network. This is the first study for the region using such a large dataset.

Interaction of Number Magnitude and Auditory Localization
Perception, 2015The interplay of perception and memory is very evident when we perceive and then recognize familiar stimuli. Conversely, information in long-term memory may also influence how a stimulus is perceived. Prior work on number cognition in the visual modality has shown that in Western number systems long-term memory for the magnitude of smaller numbers can ...

Local magnitude, surface wave magnitude and seismic energy
Studia Geophysica et Geodaetica, 1991The local magnitude ML at the seismological station Pruhonice (PRU) was converted into surface wave magnitude MS using the formula MS=−3.2+1.45 ML and the seismic wave energy was estimated using the relation log E (Joule)=1.2+2.0 ML. It was proposed to apply the same conversion formulae at seismological stations Kasperske Hory (KHC) and Berggiesshubel (

Image reconstruction from localized Fourier magnitude
Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002Fourier transform magnitude is, in many cases, the only measurable data in fields such as optics, X-ray imaging, crystallography and astronomy. Spectral phase information is impractical to obtain in these instances, due to the relatively short wavelength involved.

Local magnitude scale for earthquakes in Turkey
Journal of Seismology, 2016Based on the earthquake event data accumulated by the Turkish National Seismic Network between 2007 and 2013, the local magnitude (Richter, Ml) scale is calibrated for Turkey and the close neighborhood. A total of 137 earthquakes (Mw > 3.5) are used for the Ml inversion for the whole country.

A Local Magnitude Scale ML for the United Kingdom
Bulletin of the Seismological Society of America, 2013We have developed a new local magnitude scale ML for the United Kingdom (UK) to replace the Hutton and Boore (1987) scale developed for southern California, which has been used in the UK until now. The new UK scale is developed from 1482 observations of 85 earthquakes on 50 stations located across the British Isles and Ireland. Most of the observations

Effects of contextual and local factors on Ponzo illusion magnitude
Psychological Research, 1998Ponzo illusion has been explained by considering either just the inducing elements present in a restricted area of the visual field, the same area in which the test elements are located, or the stimulus configuration as a whole in which even the most distal figural elements – i.e., the external converging lines, here called “Ponzo wedge”– play a ...

Local Magnitude Scale for the Ethiopian Plateau
Bulletin of the Seismological Society of America, 2008A local magnitude ( M L) scale and seismicity catalog for the Ethiopian Plateau have been developed using data collected by the 2000–2002 Ethiopia Broadband Seismic Experiment. Locations for 253 local and regional events have been obtained using P -wave arrival times recorded on four or more stations.

56th U.S. Rock Mechanics/Geomechanics Symposium, 2022
ABSTRACT: The moment magnitude is the preferred magnitude to characterize the earthquake source. Moment magnitudes (Mw) are calculated from moment tensor inversion. In contrast, the regional short period surface-wave magnitude (Mblg) and local magnitude (ML) are calculated using the amplitude of the Lg surface waves

Local Magnitude, a Moment Revisited
Bulletin of the Seismological Society of America, 2006A simple theoretical analysis shows that both local magnitude M L and seismic moment M or equivalently moment magnitude M w are, in principle, measures of basic properties of the earthquake source: M L is proportional to the maximum of the moment-rate function, whereas M is proportional to its integral.
