Catalog of Nicaraguan earthquakes

Bulletin of the Seismological Society of America, 1974
abstract A documented catalog of 457 Nicaraguan seismic and volcanic events reported for the 453-year period 1520-1973 is presented. Earthquakes range in size from those that caused the destruction of the former capital at Leon in 1609, 1663 and again in 1885 to instrumentally recorded events of small magnitude.

A hybrid approach for declustering of earthquake catalogs

2023
Usually, the earthquake catalog for a given region represents a collection of all detected and localized earthquakes and, thus, contains not only the main shocks, but also fore- and aftershocks. In order to perform an independent seismic event and seismic hazard analysis we require a catalog that, ideally, contains only mainshocks. Thus, the removal of

Local Statistics of Earthquake Catalogs

1972
In analyzing earthquake catalogs one encounters the problem of distinguishing earthquakes whose occurrence is related to previous earthquakes. This paper investigates the first part of the problem: proof of the existence of interrelated earthquakes (not simply in the trivial case of aftershocks).

A catalog of earthquake related sounds

Bulletin of the Seismological Society of America, 1974
Abstract The paper is a catalog of 13 known recordings of earthquake related sounds, including circumstances relevant to the recordings. Reproductions of the recordings are also part of the paper.

Catalog of Nevada earthquakes, 1852-1960

Bulletin of the Seismological Society of America, 1965
AbstractNevada earthquakes for the period from about 1852 to 1961 are tabulated on I.B.M. punch cards. During this period 1,173 events with Nevada epicenters were felt, 586 others with Richter magnitudes above 4.0 were recorded and were probably felt by some residents, and approximately 220 were reported in nonspecific terms (e.g.

Certain problems related to earthquakes’ catalogs

2023
The quality of the earthquakes’ catalogs plays the most important role in the study of seismicity, of active faults, in seismic hazard and risk assessment, etc. The quality of the catalog is evaluated by the absence of duplicate records or explosions in itself.

Assessment of the completeness of earthquake catalogs

Geosciences Journal, 2018
Since earthquake catalogs are not complete over the magnitude range covered, one should check the completeness of catalogs before any use. To this end, I propose a new method based on the Chi-square test to assess the completeness of earthquake catalogs. The performance of the method was tested using simulated earthquake catalogs.

Modern California Earthquake Catalogs and Their Comparison

Seismological Research Letters, 2002
Earthquake catalogs are primary data sources for inferring earthquake behavior, testing earthquake pattern hypotheses, and estimating seismic hazards. As in any quantitative science, understanding uncertainties is crucial to proper interpretation. Examining catalog properties will also help guide future improvements in seismic observation and catalog ...

Estimating the magnitude of completeness for earthquake catalogs

2012
Assessing 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 ...
