The Signal to Noise Ratio and the Completeness Magnitude: The Effect of the COVID-19 Lockdown [PDF]

Atmosphere, 2021
We analyse the earthquakes catalogues for Italy, South California, and Greece across the COVID-19 lockdown period for each country. The results for Italy and Greece show that, even if the reduction of the signal to noise ratio has improved the earthquake

Tremors—A Software App for the Analysis of the Completeness Magnitude

Geosciences
This paper introduces a software tool developed within the MATLAB environment, called Tremors, aimed at streamlining the pre-processing and analysis of seismic catalogues, with a particular emphasis on determining the Magnitude of Completeness.

Functional shape of the earthquake frequency‐magnitude distribution and completeness magnitude [PDF]

Journal of Geophysical Research, 2012
We investigated the functional shape of the earthquake frequency‐magnitude distribution (FMD) to identify its dependence on the completeness magnitude Mc. The FMD takes the form N(m) ∝ exp(−βm)q(m) where N(m) is the event number, m the magnitude, exp(−βm) the Gutenberg‐Richter law and q(m) a detection function.

Spatiotemporal Distribution of the Magnitude of Completeness and b-Values in Mainland China Based on a Fused Multi-Source Earthquake Catalog [PDF]

Entropy
The b-value is a critical parameter for gauging seismic activity and is essential for seismic hazard assessment, monitoring stress evolution in focal zones, and forecasting major earthquakes. The minimum magnitude of completeness (Mc), a key indicator of

Comparative Analysis of the Methods for Estimating the Magnitude of Completeness of Earthquake Catalogs

Izvestiya, Physics of the Solid Earth, 2022
Abstract —The magnitude of completeness $${{M}_{c}}$$ of the earthquakes above which 100% of events are thought to be reliably detected is a vital parameter characterizing the completeness of seismic data. A known fact is that to

Temporal and spatial variations in the magnitude of completeness for homogenized moment magnitude catalogue for northeast India

Journal of Earth System Science, 2012
Northeast India region is one of the most seismically active areas in the world. Events data for the period 1897–2010, used in this study has been largely compiled from global ISC, NEIC and GCMT databases. Historical seismicity catalogue of Gupta et al (1986) and some events data from the bulletins of India Meteorological Department are also used ...

Performance of large language models as a source of clinical information on bacteriophage therapy [PDF]

npj Viruses
Bacteriophage therapy is re-emerging as a potential strategy to address antimicrobial resistance, but standardized patient education materials are limited. Large language models (LLMs) are increasingly used for patient-facing medical information.

PEMETAAN MAGNITUDE OF COMPLETENESS (Mc) UNTUK GEMPA DI WILAYAH BENGKULU

JGE
Dengan menggunakan data gempa bumi dari katalog USGS dan BMKG dari tahun 2009 hingga 2021, penelitian dilakukan untuk mengestimasi nilai Mc, nilai-b, dan nilai-a. Gempa bumi terjadi pada 6° LS - 2° LU dan 100° BT - 103° BT, dengan magnitudo 3 SR hingga 7

Estimating Magnitude Completeness in Earthquake Catalogs: A Comparative Study of Catalog‐Based Methods

Journal of Geophysical Research: Solid Earth
Abstract 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.
