A unified moment magnitude earthquake catalog for Northeast India
Geomatics, Natural Hazards and Risk, 2021 Earthquake-related studies on seismicity and seismic hazard assessment need a homogenous earthquake catalog for the region studied. A homogenous earthquake catalog for Northeast India region was compiled using derived regional and global empirical ...

Advanced Unified Earthquake Catalog for North East India
Applied Sciences (Switzerland), 2023 Northeast India is one of the world’s most seismically active regions. The event data included in this research for the period 1737–2012 is mostly obtained from worldwide database agencies such as ISC, NEIC, and GCMT.

Journal of Geophysical Research: Solid EarthAbstract Without careful attention to the earthquake catalog completeness, claims of novel discoveries or forecasting skills lack credibility. Estimating the completeness magnitude ( M c ) is therefore a critical step in seismological analysis.

Nowcasting Earthquakes With Stochastic Simulations: Information Entropy of Earthquake Catalogs
Earth and Space ScienceEarthquake nowcasting has been proposed as a means of tracking the change in large earthquake potential in a seismically active area. The method was developed using observable seismic data, in which probabilities of future large earthquakes can be ...

HOMOGENEOUS CATALOGS OF EARTHQUAKES [PDF]
Proceedings of the National Academy of Sciences, 1969 The usual bias in earthquake catalogs against shocks of small magnitudes can be removed by testing the randomness of the magnitudes of successive shocks. The southern California catalog, 1933-1967, is found to be unbiased in the sense of the test at magnitude 4 or above; the cutoff is improved to M = 3 for the ...
