Assessment of fault: activity forms an important part of any seismic: safety program,. It begins by locating the traces of existing faults. Fault breaks can be located 'by interpretation of aerial photographs, and on the ground mapping, Remote sensing, when conducted together with existing geological and geophysical data, is a relatively fast and cost-effective method., It contributes, enormously to locating the traces of young-looking fault 'breaks. Potentially active 'faults can generally be recognized by topographic features or by contrast in vegetation reflecting varying groundwater depth or soil differences across the fault: traces. In this method» it is important to recognize fault-generated morphological elements,. Remote sensing is. an effective technique for evaluating the potentially active faults.. As an example of the application of remote sensing of young faults, the Helendale fault zone in. the Mojave Desert: of southern. California was. studied in detail to detect the fault related topographic features.

Fay aktivitesinin saptanması her sismik koruma programının önemli bir kısmını oluşturur. Bu, mevcut fayların izlerinin belirlenmesiyle başlar. Fay izleri, hava fotoğraflarının yorumu ve yerinde karîtaiama ile tayin edilir,. Bu çalışmanın amacı hava- fotoğraflarının yorumunda kullanılan fay özelliklerinin bir katalogunu sunmaktır. Uzaktan algılama, mevcut jeolojik ve jeofizik verilerle birlikte uygulandığında genç görünümlü fayların değerlendirilmesinde çalışmaya hız kazandıran ve çalışma maliyetini azaltan bir yöntemdir. Bu yöntem, özellikle fay aktivitesinin saptanmasında mevcut fayların yerlerinin tespitine önemli katkılar sağlar., Potansiyelce aktif faylar arazide genellikle topoğrafik özellikler veya fay izleri karşısındaki bitki örtüsü kontrastı veya zemin farklılığı ile tanınabilir. Uzaktan algılamayla genç-görünümlü fayların saptanmasında, faylanmamn yarattığı morfolojik öğelerin tanınması önemlidir. Bu morfolojik belirginliklerin başında fay diklikleri, hendekler, dar ve derin çentikler, lineer sırtlar ve vadiler, sedler, çöküntü havzaları, basınç sırtları,, küçük gölcükler, kaynakların diziliminde ve/veya bitki örtüsündeki çizgisellikler,, tepe dibi çukurluklar ve önü keSilmiş ve ötelenmiş dere yatakları gelir. Bu özelliklerin gelişimi tekrarlanan fay hareketi ve fay boyuncaki çökelme ve erozyon etkilerine bağlıdır, Genç görünümlü fay özelliklerinin korunması ise esas olarak iklime bağlı olup, bunlar kurak iklim bölgelerinde uzun süre korunabilirler.. Uzaktan algılama potansiyelce aktif fayların değerlendirilmesinde uygun bir yöntemi oluşturur., Genç fayların uzaktan algılama uygulamasına bir örnek olarak, güney California'nın Mojave Çölü'nde yer alan Helendale fay zonu,/aylanmanın oluşturduğu topoğrafik Özellikleri belirlemetiçin, ayrıntılı olarak incelenmiştir..
