ÖzDeprem konumları belirli bir bölgenin sismisitesini yansıtır. Deprem konumu sismik tehlike ve risk analizi çalışmalarında kullanılan önemli bir parametredir. Deprem konumlarının belirlenmesinde ve doğrulanmasında çok disiplinli teknikler uygulanır. Bunlar aletsel sismoloji, tarihsel sismoloji ve arkeosismolojik yöntemlerdir. Aletsel sismolojik veriler 1900'lü yıllardan itibaren sismik cihazlarla elde edilen verilerdir. Tarihsel deprem verileri, depremlere tanık olan kişilerin gözlemleri ve kayıtları, insan yapımı eserler, jeolojik gözlemler, tarihsel sismoloji, paleosismoloji ve arkeosismoloji çalışmaları sonucunda elde edilir. Tarihsel depremler fay konumlarının günümüzde tam olarak tanımlanamadığı bölgelerde önemli bilgiler sağlar. Bu çalışmada tarihsel deprem kataloglarının hazırlanması amacıyla kullanılan yöntemler derlenmiştir..
Earthquake size is one of the most fundamental source parameters used in seismic catalogs. A reliable measure of the "size" of an earthquake is essential for seismological, geological, engineering, and scientific research. The size of a seismic source is measured using two parameters; damage caused (intensity) and energy released (magnitude). Intensity describes the strength of a seismic event in terms of human recognition, affected region, damage to structures. Intensity scales are valuable not only for the pre-instrumental period for historical earthquakes but also for seismic risk analysis. The intensity scale is classified by macroseismic scales. Intensity depends on local geological conditions, distance from the source that make the objective estimates difficult. The concept of magnitude was introduced by Richter to provide an objective measure of earthquake size. The advent of seismic recording systems made it possible to determine the strength of a seismic event from instrumental data. The magnitude of an earthquake provides quick information on the strength of a seismic event for the public and are essential for cataloging. Changes in instrumentation and magnitude formulation resulted from the calculation of different magnitude scales. In order to obtain a non-saturating uniform magnitude scale, seismic moment magnitude (Mw) is developed based on source parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
