An update of Algerian’s seismic catalog from historical seismicity, archeoseismological, and paleoseismological studies

Arabian Journal of Geosciences, 2021
For any seismic hazard study, a reliable, homogenized, and complete seismic catalog is required. The Algerian seismicity catalog has been recently updated by retrieving and reappraising many historical events. The Algerian seismic network has also been densified up to about 80 seismic stations covering the Tell Atlas which is the most active area of ...

Clustering analysis of the seismic catalog of Iran

Computers and Geosciences, 2009
Identification and classification of different seismotectonic provinces with similar characteristics in a region of interest is one of the most important subjects in seismic hazard studies. This task is usually done through subjective interpretations based on geological and seismotectonic information.

A Unified Seismic Catalog for the Iranian Plateau (1900-2011)

Seismological Research Letters, 2013
Online Material: De‐clustered and non‐declustered earthquake catalogs. The first seismograph in Iran was installed in 1959, and this marked the beginning of the national seismic catalog. The seismic network grew with years, but its coverage, the instrumental features, and the details of magnitude calculation changed over time, resulting in a highly ...

Seismicity in Poland: Updated Seismic Catalog

2015
A short overview is presented of seismicity in Poland, based on historical data and, since the 1980s, instrumental records. As a level of seismicity is low, in most of the country no earthquakes have been recorded instrumentally, seismicity is extremely poorly recognized. There are areas known historically from the occurrence of earthquakes of Io = 6–7

(Re)Discovering the Seismicity of Antarctica: A New Seismic Catalog for the Southernmost Continent

Seismological Research Letters
Abstract We apply a machine learning (ML) earthquake detection technique on over 21 yr of seismic data from on-continent temporary and long-term networks to obtain the most complete catalog of seismicity in Antarctica to date. The new catalog contains 60,006 seismic events within the Antarctic continent for 1 January 2000–1 January 2021,

Effect of Earthquake Catalog Declustering on Seismic Hazard Assessment

Seismic Instruments, 2019
The paper investigates the effect of different methods for preprocessing earthquake catalogs (declustering, i.e., removal of dependent events from them, and selection of the magnitude of completeness) on seismic hazard assessment. Seismic catalogs of the Kamchatka and Caucasus regions have been used for the analysis, because synthetic catalogs do not ...
