    Relations between the GNSS, InSAR, and the other techniques for prediction of earthquakes
    (Springer Heidelberg, Tiergartenstrasse 17, D-69121 Heidelberg, Germany, 2015-09) Urusan, Ahmet Y.
    It is a well-known fact that the earthquakes have a lot of different parameters. Modern technology allows us to observe an important part of these settings. For example, when an earthquake occurs, its location, time, and depth, etc., values are measured by a seismometer. Recently, using the modern technologies, Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) give us a chance to predict earthquakes in the short or long term. For avoiding the destruction the force of an earthquake can bring to human beings, it is inevitable to use the newer techniques. To predict out about the expected main shock, someone must begin to study firstly earthquakes which have already occurred. In this research, the seismometer and acceleration-meter data have been evaluated and compared by the geodetic measuring data of the InSAR and GPS data for Van earthquake on 23 October 2011. The area of research made out by the InSAR technique and the deformations produced by the GPS technique are being tested under centimeter precision. Additionally, the ionospheric total electron content values obtained by the GPS method have been considered, and the ionospheric distortions acquired from the closest Continuously Operating Reference Stations-Turkey stations, particularly Muradiye station, have been observed. Also, they have been interpreted geophysically.

    The Earth's magnetic field lines and earthquake relations
    (Amer Inst Physics, 2 Huntington Quadrangle, Ste 1No1, Melville, Ny 11747-4501 USA, 2011) Ürüşan, Ahmet Yücel; 114677
    Earthquake is one of the natural disasters and very important for human life. A lot of people die every year all over the world due to earthquakes. It is very difficult to develop early warning method for earthquakes because of it has 3000 parameters. The earthquake scientists and other people involved are very hard working about this matter. Governments allocate a significant budget for earthquakes. In this study, the earth magnetic field has been researched for early warning. The questions are any tectonic plate movement is effect of the Earth magnetic field lines or changing of the Earth magnetic field lines are effect any tectonic plate. Greater than 7 M earthquakes have been chosen in this study. And 12 years period changing graphics of the earth magnetic field lines where the chosen earthquake locals have been taken.
