The morphotectonic analysis is a useful time-saving and cost-effective method to assess tectonic activity, especially in large regions. In this paper, the study was carried out Kerman city which southeast of Iran part Central structural zone. Despite occurrence numerous historical instrumental earthquakes around city, there gap earthquake records that has obscured its seismicity status. aim ide...

Using borehole strainmeters, we detected a 13-day long slow slip event in 2011 with Mw = 5.45 on the Longitudinal Valley Fault, Taiwan. It has been likely promoted by significant Coulomb stress changes (∼0.5–1 MPa) imparted combination of coseismic and postseismic 2003 Chengkung earthquake. kinematic models, infer that accommodated about 15%–35% deficit accumulated from 1997 to its source regio...

Gully erosion is one of the most significant erosion types. This type of erosion is one of the most important sources of sediment in different regions of the world. Gullies often have different dimensions and complex characteristics and these characteristics may affect the distribution of vegetation. Topographic characteristics of gullies provide complex ecosystem for vegetation establishment. ...

the goal of this article is to study the shimashki potteries in the saymarreh valley. archaeological surveys conducted in the saymarreh valley shows that the painted pottery tradition of godin iii has become prevalent in the valley during the bronze age and only once, development of this pottery tradition had cracked. this event took place in the phase of godin iii4, which we relate it to the i...

We present a new three-dimensional inventory of the southern San Francisco Bay area faults and use it to calculate stress applied principally by the 1989 M = 7.1 Loma Prieta earthquake and to compare fault seismicity rates before and after 1989. The major high-angle right-lateral faults exhibit a different response to the stress change than do minor oblique (right-lateral/thrust) faults. Seismi...

Conflicting views of circum-Pacific tectonics have focused on the PhilippinesTaiwan region, where there has been neither convincing documentation nor general agreement on the importance of transcurrent (strike-slip) faulting or the possible sense of regional horizontal displacement. Structural and physiographic features of the 1200-km-long Philippine fault zone are fully as spectacular as those...

On 24 August 2014, the M 6.0 South Napa earthquake shook much of the San Francisco Bay area, leading to significant damage in the NapaValley. The earthquake occurred in the vicinity of the West Napa fault (122.313° W, 38.22° N, 11.3 km), a mapped structure located between the Rodger’s Creek and Green Valley faults, with nearly pure right-lateral strike-slip motion (strike 157°, dip 77°, rake –1...
