The limits of a recently proposed universal scaling law for the probability distributions of earthquake recurrence times are explored. The scaling properties allow to improve the statistics of occurrence of large earthquakes over small areas by mixing rescaled recurrence times for different areas. In this way, the scaling law still holds for events with M≥5.5 at scales of about 20 km, and for M...

Iran is well known for having countless historical and instrumental records of tectonic events. Shahriary catchment, as a study area, is part of the Zagros collision seismic province. This research aimed to introduce a new method which is useful in identifying the relative active tectonic events of an area. The research method was designed in order to calculate the relative active tectonic inde...

The reservoir-induced seismicity (RIS) at the Karkheh dam site with a reservoir capacity of about 7.4x109 meters is investigated. Based on the assessment of the seismicity of the dam site in equal time periods before and after reservoir impoundment, it was found that the number of earthquakes have been tripled after impoundment, while their magnitudes and focal depths become smaller. The averag...

The role of information structure in determining the placement of pitch accent in English is often reduced to notions of Focus (e.g. Chomsky, 1971; Vallduvı́, 1990; Rooth, 1992; Roberts, 1996) and Givenness (e.g. Chafe, 1974; Schwarzschild, 1999; Féry & Samek-Lodovici, 2006; Selkirk, 2007). In question-answer pairs like the following,1 the default sentential stress pattern of English, where the ...

Non-structure preserving phonological processes are defined by the emergence of a segment which is assumed to be absent from the lexical inventory of the language in question and, hence not contrastive. A central tenet of Optimality Theory (OT; Prince & Smolensky 1993/2004, McCarthy & Prince 1993, 1995, 1999), the Richness of the Base Hypothesis (RotB; Prince & Smolensky 1993) states that lingu...

The spatial distribution of seismicity is often used as one of the indicators of zones where future large earthquakes are likely to occur. This is particularly true for intraplate regions such as the central and eastern United States, where geology is markedly enigmatic for delineating seismically active areas. Although using past seismicity for this purpose may be intuitively appealing, it is ...

[1] We establish a connection between geometry of the faults’ network in a region and seismicity preceding the strong earthquakes in the intermediate-term timescale of years. Previous studies of observed and computer-simulated seismicity demonstrated that strong earthquakes are preceded in that timescale by the rise of seismic activity in a lower magnitude range. Here, we explore a complementar...

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....
