We investigate the distribution of aftershock zones for large earthquakes (scalar seismic moment M ≥10 19.5 N m, moment magnitude, m ≥7). Mainshocks are selected from the Harvard centroid moment tensor catalog, and aftershocks are selected from the Preliminary Determination of Epicenters (NEIC) catalog. The aftershock epicenter maps are approximated by a two-dimensional Gaussian distribution; the major ellipse axis is taken as a quantitative measure of the mainshock focal zone size. The… Expand

Empirical Relationships between Aftershock Zone Dimensions and Moment Magnitudes for Plate Boundary Earthquakes in Taiwan
In this study, we establish the empirical relationships between the spatial dimensions of the aftershock zones and moment magnitudes ( M w) for the Taiwan region. The length ( l ) and width ( w ) ofExpand
On Mainshock Focal Mechanisms and the Spatial Distribution of Aftershocks
Despite previous observations that aftershocks lie preferentially along the fault planes of mainshocks, many branching models for earthquake occurrences do not directly incorporate information on theExpand
Maximal radius of the aftershock zone in earthquake networks
In this paper, several seismoactive regions were investigated (Japan, Southern California and two tectonically distinct Japanese subregions) and structural seismic constants were estimated for eachExpand
ESTIMATING AFTERSHOCK AREA BASED ON THE MAINSHOCK INFORMATION
The paper considers the task of quick estimating an area where aftershocks are expected after a strong earthquake using information about its mainshock. The suggested approach is based on theExpand
Optimal Scaling of Aftershock Zones using Ground Motion Forecasts

Magnitude Limits of Subduction Zone Earthquakes
Maximum earthquake magnitude ( m x ) is a critical parameter in seismic hazard and risk analysis. However, some recent large earthquakes have shown that most of the existing methods for estimating mExpand
Quantifying early aftershock activity of the 2004 mid-Niigata Prefecture earthquake (Mw6.6)
[1] We analyze the early aftershock activity of the 2004 mid-Niigata earthquake, using both earthquake catalog data and continuous waveform recordings. The frequency-magnitude distribution analysisExpand
Complexity, aftershock sequences, and uncertainty in earthquake statistics
Earthquake statistics is a growing field of research with direct application to probabilistic seismic hazard evaluation. The earthquake process is a complex spatio-temporal phenomenon, and has beenExpand
Earthquake size distribution : Power-law with exponent β ≡ 1 2 ?
We propose that the widely observed and universal Gutenberg-Richter relation is a mathematical consequence of the critical branching nature of earthquake process in a brittle fracture environment.Expand
