Multiple magnitudes and their cleverness
地震科学进展, 2022 Magnitude is a measure of the size of an earthquake. In practical work such as seismic activity analysis, people usually think that an earthquake has only one magnitude. Many people will have such doubts：why use multiple magnitudes?

Seismica, 2023 The creation of a homogenized earthquake catalog is a fundamental step in seismic hazard analysis. The homogenization procedure, however, is complex and requires a good understanding of the heterogeneities among the available bulletins.

Frontiers in Earth Science, 2021 To reduce the probability of future large earthquakes, traffic light systems (TLSs) define appropriate reactions to observed induced seismicity depending on each event's range of local earthquake magnitude (ML).

Earth and Planetary Physics, 2021 With the development of unconventional shale gas in the southern Sichuan Basin, seismicity in the region has increased significantly in recent years. Though the existing sparse regional seismic stations can capture most earthquakes with \begin{document}$

Local Magnitude Tomography in California [PDF]
Bulletin of the Seismological Society of America, 2011 Lateral variation in crustal attenuation of California is calculated by inverting 25,330 synthetic Wood–Anderson amplitudes from the California Integrated Seismic Network (CISN) for site, source, and path effects. Two-dimensional attenuation ( q or 1/ Q ) is derived from the path term, which is calculated via an iterative least-squares inversion that ...

Expanding Moment Magnitude Pools for Earthquake Magnitude Homogenization
Applied Sciences, 2022 A comparison on the influence of different moment magnitude pools on magnitude homogenization regressions was presented. The control moment magnitude pool is composed of earthquake records from GCMT.

Terrestrial, Atmospheric and Oceanic Sciences, 2022 Key points logEs is proportional to 2.0ML for the Shoufeng earthquake sequence in Taiwan. A crossover magnitude detected at ML = 4.0 divides the MW–ML relation into two parts. For ML > 4.0, logM0 ∝ 0.67ML and MW ∝ ML; for ML

The Local Magnitude Scale in the Korean Peninsula
Pure and Applied Geophysics, 2002 A formula to determine the local magnitude (ML) following Richter’s original definition was empirically derived for the Korean Peninsula. A total of 1,644 digital seismograms from 142 Korean earthquakes that occurred from 1997 to 2000 were corrected for instrument response and convolved with the nominal Wood-Anderson torsion seismograph response to be ...
