Comparing the Hawkes and Trigger Process Models for Aftershock Sequences Following the 2005 Kashmir Earthquake
In an earlier study (Van Lieshout and Stein in Math Gesoci 44(3):309–326, 2012) we postulated the existence of two major earthquakes in the 2005 Kashmir disaster instead of a single one, based upon the pattern of aftershocks. In this study, we explore this hypothesis further by fitting several spatial point pattern models. In particular, we discuss the Hawkes and the trigger process models for ...
متن کاملDecay and expansion of the early aftershock activity following the 2011, Mw9.0 Tohoku earthquake
[1] The 2011, Mw9.0 Tohoku earthquake was followed by an abundant amount of seismicity providing a unique opportunity to analyze the triggering mechanism of great earthquakes. Although the Tohoku earthquake occurred close to a dense seismic network, many aftershocks that occurred in the first few hours after the mainshock are not recorded in the earthquake catalogs. Here we use a template wavef...
متن کاملQuantifying 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 frequencymagnitude distribution analysis of the Japan Meteorological Agency (JMA) catalog shows that the magnitude of completeness of the aftershocks changes from values around 5.0, immediately after the main shock, to about 1.8, 12 hours la...
متن کاملAftershock seismicity of the 2010 Maule Mw=8.8, Chile, earthquake: Correlation between co-seismic slip models and aftershock distribution?
[1] The 27 February 2010 Maule, Chile (Mw=8.8) earthquake is one of the best instrumentally observed subduction zone megathrust events. Here we present locations, magnitudes and cumulative equivalent moment of the first 2 months of aftershocks, recorded on a temporary network deployed within 2 weeks of the occurrence of the mainshock. Using automatically-determined onset times and a back projec...
متن کاملSource Process of the Great 1977 Sumba Earthquake
In order to investigate the applicability of the asperity model to intraplate earthquakes we have studied the rupture process of the great 1977 Sumba normal-faulting earthquake (Mw=8.2-8.3), one of the largest earthquakes since 1963. This event has been variously interpreted as a plate detachment event (i.e., rupture through the entire lithosphere) or a shallow plate-bending event. We have anal...
