Clustering Networks Based on Physarum Optimization for Seismic Catalogs Analysis

2019 IEEE Congress on Evolutionary Computation (CEC), 2019
Physarum optimization becomes popular after Liu et al in 2015 applied it for solving Steiner tree problem in networks. It has been effective in designing complicated road transportation networks, drug similarity networks and node-weighted protein-protein interaction network for cancer.

The 2018 update of the US National Seismic Hazard Model: Overview of model and implications

, 2020
During 2017–2018, the National Seismic Hazard Model for the conterminous United States was updated as follows: (1) an updated seismicity catalog was incorporated, which includes new earthquakes that occurred from 2013 to 2017; (2) in the central and ...

Statistical Analysis of Earthquake Catalogs for Seismic Hazard

1987
In 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 ...

Development of the 2017 national seismic hazard maps of Indonesia

, 2020
Indonesia is one of the most seismically active countries in the world, and its large, vulnerable population makes reliable seismic hazard assessment an urgent priority.

Windowed ETAS models with application to the Chilean seismic catalogs

Spatial Statistics, 2015
Abstract 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 ...

Forecasting the Long-Term Spatial Distribution of Earthquakes for the 2023 U.S. National Seismic Hazard Model Using Gridded Seismicity

Bulletin of The Seismological Society of America (BSSA)
Probabilistic seismic hazard analyses such as the U.S. National Seismic Hazard Model (NSHM) typically rely on declustering and spatially smoothing an earthquake catalog to estimate a long-term time-independent (background) seismicity rate to forecast ...

On estimating the amount of blasts in seismic catalogs with Schuster's method

Bulletin of the Seismological Society of America, 1994
Abstract 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.

Maintenance of a seismic network in Bangladesh and an initial earthquake catalog

2021
Bangladesh is a densely populated country located on the north-eastern side of the India-Eurasia collision zone. The eastern half of the country is underlain by the seismically active Chittagong-Myanmar Fold and Thrust Belt, which forms the accretionary prism associated with the eastward-subducting Indian Plate, and is bordered to the north by the ...

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.
