Magnitude of completeness for the Northern stations of the Egyptian National Seismological Network
Arabian Journal of Geosciences, 2020After the occurrence of an earthquake near Cairo on October 1992 (Mw 5.8), the Egyptian authorities established the Egyptian National Seismological Network (ENSN), which was targeted to monitor the seismic activity in and around Egypt. The ENSN started operation in 1997 with 66 stations installed by the National Research Institute of Astronomy and ...

NUMERICAL TESTS ON CATALOG‐BASED METHODS TO ESTIMATE MAGNITUDE OF COMPLETENESS
Chinese Journal of Geophysics, 2016AbstractThis study compares five methods for estimating the completeness magnitude Mc threshold of earthquake catalogs through applying them to synthetic catalogs generated from 3 different models. We have found that the Median‐based analysis of the segment slope (MBASS) method is suitable for catalogs recorded by networks whose detection capability ...

Earthquake Catalog‐Based Machine Learning Identification of Laboratory Fault States and the Effects of Magnitude of Completeness [PDF]
Geophysical Research Letters, 2018 Machine learning regression can predict macroscopic fault properties such as shear stress, friction, and time to failure using continuous records of fault zone acoustic emissions.

Centre and magnitude of vertical forces in complete denture wearers
Journal of Oral Rehabilitation, 1995summary The aim of this study was to examine the centre and magnitude of a vertical component of occlusal forces in complete denture wearers during several activities using a newly developed method. A lower complete denture was divided into upper and lower parts parallel to the occlusal plane.

Multiscale Mapping of Completeness Magnitude of Earthquake Catalogs
Bulletin of the Seismological Society of America, 2013We propose a multiscale method to map the spatial variations of the com- pleteness magnitude Mc of earthquake catalogs. The Gutenberg-Richter law describ- ing the earthquake frequency-magnitude distribution (FMD) might not hold over the entire magnitude range, and small areas may exhibit a specific type of seismicity, especially in volcanotectonic ...

A complete rockfall inventory across twelve orders of magnitude.
2022<p>Understanding the magnitude-frequency relationship of rock falls is one of the most important issues for both geomorphologists assessing sediment budgets as well as public stakeholders evaluating rock fall hazards. Multi-temporal Terrestrial Laser Scanning (TLS) surveys, or more general LiDAR, is often applied to produce rock fall ...

Estimating the magnitude of completeness for earthquake catalogs
2012Assessing the magnitude of completeness Mc of instrumental earthquake catalogs is an essential and compulsory step for any seismicity analysis. Mc is defined as the lowest magnitude at which all the earthquakes in a space-time volume are detected. A correct estimate of Mc is crucial since a value too high leads to under-sampling, by discarding usable ...

Analysis of the Completeness Magnitude and Seismic Network Coverage of Japan
Bulletin of the Seismological Society of America, 2010Abstract A reliable estimate of completeness magnitude, M c , above which all earthquakes are considered to be detected by a seismic network, is vital for seismicity-related studies. We show a comprehensive analysis of M c in Japan. We use the catalog maintained by the Japan Meteorological Agency (JMA) and also available information on seismic ...

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 ...

Effects of magnitude accuracy and completeness data on seismic hazard parameters
Acta Seismologica Sinica, 1996This paper is aimed to solve the question that present seismic catalogs are incomplete. The authors improve the maximum likelihood method to estimate seismic hazard parameters, considering different accuracy and completeness. As an example, we calculated the seismic hazard parameters of Fen-Wei Seismic Belt and South Shaanxi Region. And based on it, we
