CARS - Catalog of Relative Seismic Locations of 1981-2018 Italian Seismicity
2023The Istituto Nazionale di Geofisica e Vulcanologia (INGV) monitors the Italian peninsula seismicity by using the data recorded by the Italian National Seismic Network (RSN) together with the ones gathered by other permanent regional networks (PRN).

Periodicity in seismicity: examination of four catalogs
Tectonophysics, 1991Abstract Seismic activity in four different catalogs is examined for periodicity, both in terms of yearly energy release and number of earthquakes per year. The four catalogs examined cover different areas in different time windows: the Mohns Ridge (a segment of the northern Mid-Atlantic Ridge) (1960–1988), earthquakes felt in Norway (1891–1989 ...

Seismicity in Poland: Updated Seismic Catalog
2015A 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

Seismic Eruption Catalog of Strokkur Geyser, Iceland
2020<p>Geysers are hot springs whose frequency of water eruptions remain poorly understood. We setup a local broadband seismic network for one year at Strokkur geyser, Iceland, and developed an unprecedented catalog of 73,466 eruptions.

Windowed ETAS models with application to the Chilean seismic catalogs
Spatial Statistics, 2015Abstract The seismicity in Chile is estimated using an ETAS (Epidemic Type Aftershock sequences) space–time point process through a semi-parametric technique to account for the estimation of parametric and nonparametric components simultaneously. The two components account for triggered and background seismicity respectively, and are estimated by ...

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

Statistical Analysis of Earthquake Catalogs for Seismic Hazard
1987In the use of historical earthquake catalogs for seismic hazard, the main objective is to estimate the rate of earthquakes of various sizes in a region around the site of interest. This is a complicated problem, in part because of deficiencies of the catalog such as missing data, nonuniformity of the scale in which earthquake sizes are measured and ...

Effect of Earthquake Catalog Declustering on Seismic Hazard Assessment
Seismic Instruments, 2019The 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 ...

On estimating the amount of blasts in seismic catalogs with Schuster's method
Bulletin of the Seismological Society of America, 1994Abstract The events in a seismic catalog are represented by phasors of unit amplitude and with phase angles determined from the local time of occurrence of the events. A graphical display of the cumulative sum of these phasors reveals information about the distribution of the events in the catalog.

Towards an Improved Seismic Source Catalog for Switzerland
We present an updated and extended seismotectonic earthquake catalog of Switzerland and surrounding regions. This SECOS25 catalog serves as input for the seismic-source component of Switzerland’s next generation seismic hazard model to be developed by the Swiss Seismological Service (SED) over the coming years.Tobias Diehl +8 more
