landslides and slope instabilities are major hazards for human activities often causing economiclosses and property damages. sikan river basin (ilam province) due to the topography, tectonic,lithology, and climate has enough potential for occurrence of this phenomenon. the objectives of thisstudy were to determine effective parameters controlling the landslide occurrence and to preparezonation ...

a prerequisite to seismic hazard assessment is to have knowledge of historical and prehistorical earthquakes. to obtain such data, researchers have already practiced different methods including historical seismology, paleoseismology, and recently archaeoseismology. archaeoseismology is a multidisciplinary approach which ideally tries to find the age, epicenter, and magnitude of past earthquakes...

Besides precipitation, a major trigger for landslides is earthquake. Landslides triggered by earthquake always cause significant fatalities and economic loss. Therefore it is needed to improve basic understanding of the technical, financial and social risks posed by earthquakes triggered landslides. Furthermore basic understanding of processes and cascading hazards related to earthquake trigger...

Background: Many types of natural disasters are sudden and calamitous events that create a large socioeconomic burden with significant negative impact on health care, social infrastructure, and the environment; especially in the low and middle income countries; therefore, it is necessary to reduce or control this kind of disasters by understanding the specific risks and negative impacts. Recogni...

the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...

Tembalang and Banyumanik are two sub-districts in the Semarang City that morphologically have fairly steep hill so they considerable potential to experience landslides. In addition morphology, some of these areas traversed by regional geological structures. This study is investigate relationship between landslides developing structures areas. The research methods include interpretation presence...

in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...

The durability of natural stone in traditional buildings is important for the structures to survive today. External environmental factors have negative effects on materials. When material exposed factors, deterioration occurs stone. It determine this and its causes correctly offer solutions transfer future generations. Failure identify that cause leads growth damages formation new damages. Dete...

The landslides cause several casualties and economic losses all over the world. Studies show that most casualties happen within the first 18-35 minutes after the burial. This demands life-detecting systems to be available immediately on the spot after the disaster. A suggested approach is deploying multiple units of these instruments across the country. Main constraint in developing countries f...
