Declustering aims to divide earthquake catalogs into independent events (mainshocks), and dependent (clustered) events, and is an integral component of many seismicity studies, including seismic hazard assessment. We assess the effect of declustering on the frequency-magnitude distribution of mainshocks. In particular, we examine the dependence of the b-value of declustered catalogs on the choice of declustering approach and algorithm-specific parameters. Using the catalog of earthquakes in…

Question-driven ensembles of flexible ETAS models

The development of new earthquake forecasting models is often motivated by one of the following complementary goals: to gain new insights into the governing physics and to produce improved forecasts

A preliminary report on seismicity declustering methods and completeness magnitude in eastern Sunda Arc

Data declustering separates mainshocks from both foreshocks and aftershocks while a reliable estimate of completeness magnitude is a key point in seismic parameter determination. These play a role in

Regional Characteristics of Observable Foreshocks

Measures of foreshock occurrence are systematically examined using earthquake catalogs for eight regions (Italy, southern California, northern California, Costa Rica, Onshore Japan, Alaska, Turkey,

Estimation of B-Value Variation as Earthquake Precursor in Java Region with Maximum Likelihood Method

Java Island is one of the areas with a population density of 1,171 people/km2, which is relatively high compared to other regions in Indonesia. The tectonic setting of the Java region is affected by

Seismic recurrence parameters for India and adjoined regions

This article focuses on estimating the seismic recurrence parameters of India and adjoining regions based on a comprehensive catalogue assimilated from various sources. The study region encompasses

Worldwide Statistical Correlation of Eight Years of Swarm Satellite Data with M5.5+ Earthquakes: New Hints about the Preseismic Phenomena from Space

Nowadays, the possibility that medium-large earthquakes could produce some electromagnetic ionospheric disturbances during their preparatory phase is controversial in the scientific community. Some

Solving three major biases of the ETAS model to improve forecasts of the 2019 Ridgecrest sequence

Strong earthquakes cause aftershock sequences that are clustered in time according to a power decay law, and in space along their extended rupture, shaping a typically elongate pattern of aftershock

Modeling and Prediction of Aftershock Activity

We provide an overview of the basic models of the aftershock processes and advanced methods used to predict postseismic hazard. We consider both the physical mechanisms for aftershock generation and

The absence of self-similarity across a broad range of magnitudes in the distribution of declustered earthquakes is an argument against the application of an assumption of scale-independence to models of main-shock earthquake occurrence, and in turn to the use of such models to justify the assertion that earthquakes are unpredictable.

The Effect of a Mainshock on the Size Distribution of the Aftershocks

A systematic decay of the aftershock rate over time is one of the most fundamental empirical laws in Earth science. However, the equally fundamental effect of a mainshock on the size distribution of

Poisson tests of declustered catalogues

Tests that incorporate spatial information reject the SITHP hypothesis for those declustered catalogues, illustrating the importance of using spatial information and posing declustering as an optimization problem.

Stochastic Declustering of Space-Time Earthquake Occurrences

This article is concerned with objective estimation of the spatial intensity function of the background earthquake occurrences from an earthquake catalog that includes numerous clustered events in

Effects of seismic declustering on seismic hazard assessment: a sensitivity study using the Turkish earthquake catalogue

Earthquakes trigger other earthquakes and build up clusters in space and time that in turn create a bias in seismic catalogues. Therefore, declustering is considered as a prerequisite in seismic

Clustering analysis of seismicity and aftershock identification.

We introduce a statistical methodology for clustering analysis of seismicity in the time-space-energy domain and use it to establish the existence of two statistically distinct populations of

Second‐order moment of central California seismicity, 1969–1982

The second-order moment (cross-correlation function) of earthquakes in the U.S. Geological Survey central California catalog between 1969 and 1982 was calculated with respect to a magnitude threshold

These results, obtained from a complicated clustering model, are consistent with the results obtained in [Ogata, Geophys. Int. 127, 17 (1996)] by using the conventional single-linked cluster declustering method.

Aftershocks’ Effect on Structural Design Actions in Italy

Although earthquakes generally form clusters in both space and time, only mainshocks, usually the largest magnitude events within clusters, are considered by probabilistic seismic hazard analysis
