Southern Sumatra and its surroundings are close to the contact zone of Indo-Australian plate Eurasian plate, so area always relates high seismicity zone. The Sumatran subduction zone, Mentawai fault, several segments fault drive seismic activities in area. Tectonic settings essential understanding area's source hazard. This can be obtained using relocated hypocenter distribution 3D velocity mod...

The question whether the preparation process of foreshocks and mainshocks is diierent from other earthquakes is of great interest with regard to earthquake predictability. We show that the most conspicuous properties of earthquake clustering can be explained without assuming any diierences in the initiation processes. In particular, the Gutenberg-Richter law as well as the Omori law for foresho...

One of the most important and effective factors in prioritizing high accident prone segments of roads for pedestrians is accident cause which up to now has been neglected in current methods. Since accidents are not additives due to various reasons, prioritizing these segments without considering the accident cause makes the selection of high accident prone segments inaccurate. In this paper, by...

We present a detailed field structural survey of the area of interaction between the active NW-striking transform Husavik-Flatey Fault (HFF) and the N–S Theystareykir Fissure Swarm (TFS), in North Iceland, integrated by analog scaled models. Field data contribute to a better understanding of how transform faults work, at a much higher detail than classical marine geophysical studies. Analog exp...

The Carboneras fault is one of three principal Cenozoic strike-slip faults in the Betic Cordillera of southeastern Spain. In this study, we characterize the paleoseismic history of the Carboneras fault by examining the evidence for lateral offset of 85-180 ka ‘Iyrrhenian marine terraces, by dating the left-lateral stream-channel offsets in La Serrata, and by postulating a late Holocene coastal ...

the doruneh fault is one of the longest and most prominent faults in iran. however, only two recorded historical earthquakes with magnitudes more than 7 might be related to this fault. for getting more information on this fault more investigation in different fields are required. fault displacement is one of the most important parameters needed to explore the fault activity. in this study, with...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...

Abstract The Main Recent Fault (MRF) is a major active strike-slip fault system at the NE border of Arabian platform and Central Iran. Both geometry kinematics rather well known along its central part SE termination, while possible continuation to northwest ambiguous. Moreover, less regard has been paid relationships between this intracontinental other faults in NW Iran – Anatolia. This paper i...

The soil engineering geological characteristics and hidden fault creep activity are the main factors affecting stability of Beijing–Zhangjiakou high-speed railway foundation. In order to reveal deep formation structure physical mechanical properties under foundation explore influence settlement static load dynamic railways, according deep-hole drilling test, this paper reveals within a 500 m bu...
