This article explores the problem of short-term earthquake prediction based on spatio-temporal variations of seismicity. Previous approaches to this problem have used precursory seismicity patterns that precede large earthquakes with "intermediate" lead times of years. Examples include increases of earthquake correlation range and increases of seismic activity. Here, we look for a renormalizati...

The spatial-temporal pattern of seismicity, preceding 5 moderate-sized earthquakes with MD ≥ 4.1, that occurred in the Friuli-Venezia Giulia region (northeastern Italy) and in western Slovenia, is investigated with the Region-Time-Length (RTL) and the PI algorithms. These algorithms were originally formulated to reveal the variation of seismicity patterns before large earthquakes. The RTL algor...

This paper is about short review of earthquake statistics and efforts for earthquake mitigation, hazard and risk assessment studies in Pakistan. Pakistan and adjoining region lying between longitude 60 ̊E to 78 ̊E and latitude 20 ̊N to 45 ̊N are selected for the study as this region has a history of many large earthquakes because of its location in the region of intersection of three plates namely ...

9 Figure 1 The locations of the 1995 Kobe earthquake and the four other large intraplate earthquakes (Nobi, Tango, Tottori, and Fukui) in Japan since 1890. The mechanisms for the Tango, Tottori and Fukui earthquakes are also shown. The base map showing the Quaternary faults in the region is taken from Huzita (1980) and modified. M.T. is the Median Tectonic Line. Daishinsai (A major earthquake d...

We thank Rastogi for pointing out a number of factual errors in our article, and welcome this opportunity to correct several scientific misunderstandings that have crept into his manuscript. Rastogi is in agreement with our statements and conclusions concerning the seismicity in the Jaitapur region that: (a) no significant M > 6 earthquakes have been recorded by seismographs located within 50 k...

Abstract. Modelling the seismic potential of active faults and associated epistemic uncertainty is a fundamental step probabilistic hazard assessment (PSHA). We use SHERIFS (Seismic Hazard Earthquake Rate In Fault Systems), an open-source code allowing us to build models including earthquake ruptures involving several faults, model seismicity rates on North Anatolian (NAF) system in Marmara Reg...

Long-term ground deformation monitoring using the Persistent Scatterer Interferometry Wide Area Product (PSI-WAP) technique for the period 1992-2003, combined with Differential GPS measurements and seismicity analysis has provided useful information about the tectonic motions of the tectonically complex area of Patras Gulf (Western Greece), and lead to new insights on the geotectonic regime of ...

This work reviews some results obtained already for the variations of the seismicity parameters b and p in different seismogenic and tectonic regions in Japan. We bring as well new evidence that the time and space changes in seismicity parameters are correlating well with the crustal structure and/or some parameters of the earthquake process. In the first part of the paper we show that several ...

The study focuses on the spatial organization of seismicity and the relation between fracture pattern and earthquakes in the Friuli (north-eastern Italy) and western Slovenia seismic regions. The structural setting is characterized by a complex structure resulting from the superposition of several tectonic phases that generated NW-SE trending Dinaric faults and about E-W trending Alpine faults....

earthquakes are a particular concern because of the serious hazard they present. the existence of seismicity patterns such as the foreshock and aftershock clusters, doughnut pattern, seismic quiescence etc show that the earthquake occurrence in the active tectonic regions is not random and clustering phenomena are obvious characteristics of these events in space and time. fractal analysis, as a...
