The Kandilli Observatory and Earthquake Research Institute offers graduate work leading to the degrees of Master of Science and Doctor of Philosophy in:

I. Geodesy
II. Geophysics
III. Earthquake Engineering

The primary objective of the graduate program is to train specialists and/or theoreticians (required for research and teaching) in geodesy, geophysics and earthquake engineering, capable of creative and original thinking and disseminating new ideas and concepts in related activities in Turkey.

Definitions and Fundamental Goals of Geodesy, Geophysics and Earthquake Engineering:

I. Earthquake Engineering

The Earthquake Engineering program is intended for Civil Engineers who wish to specialize in earthquake ground motion, earthquake hazard assessment, the analysis of earthquake response and the earthquake-resistant design of structures and systems.

The graduate courses offered by the department encompass earthquake strong motion, earthquake hazard assessment, selection of design basis earthquake motions; site response and site effects on ground motions and building damage; earthquake resistant design procedures for buildings of reinforced concrete, steel, precast, prestressed and masonry construction; off-shore structures, earth and concrete dams, liquid storage tanks, bridges, retaining walls, equipments and secondary systems.

II. Geodesy

Geodesy deals with the measurement and representation of the earth, including its gravity field, in a three-dimensional time varying space.

The major geodetic goals may be summarized as follows:
a) Establishment and maintenance of local, regional, national, continental and global three-dimensional geodetic control networks.
b) Measurement and representation of geodynamic phenomena (polar motion, spinning, earth tides, plate motion, local crustal movements, etc.)
c) Determination of actual gravity field of the earth including temporal variations.

The objectives of the courses offered are then to provide the student with the necessary knowledge and skills for such geodetic activities as
1) Treatment of the existing national geodetic control networks,
2) Geodetic applications in global, regional and local geodynamics programs (especially in earthquake studies), and
3) Detection and monitoring of deformations of very large structures.

III. Geophysics

Geophysics deals with the time varying physical aspects of the earth. The aim of geophysics, as applied to the body of the earth, is to determine the composition and state of the interior, and the manner in which internal processes produce the observed features of the earth's surface.

The objectives of the courses offered are then:
1) To improve better understanding of the solid earth, in particular the processes that result in the movement and deformation of the tectonic plates;
2) To study all aspects of seismology such as earthquake mechanism, instrumentation and observation, earthquake prediction and earthquake hazard reduction research activities for further understanding of the processes responsible for causing earthquakes, studies of the earth's crust using geophysical methods, engineering application of geophysics, analysis of geomagnetic observations, paleomagnetic and archeomagnetic studies, data processing of the earthquake, explosion and geomagnetic data and exploration of the hydrocarbon and mineral deposits.

MASTER OF SCIENCE PROGRAMS

Graduate programs leading to the Master of Science degrees in Earthquake Engineering, Geodesy, and Geophysics normally involve two years of graduate work and include,
a) A minimum number of 24 credits of course work to be completed in two successive semesters,
b) A thesis to be completed in the following two semesters.

Of the minimum number of 24 credits, at least one-third should be comprised of required courses specified by the program in which the student is registered. The remaining two-third may be chosen from among elective courses of the program or the courses acceptable by regulations of the Institute, subject to the approval of student advisor. The 24 credits of course work is normally made up of 500 and 600 level courses; however, with the approval of the advisor, some of the program may be composed of 400 level courses, a maximum of two of which with credit, not taken in the students undergraduate program.

Upon completion of course work with a grade-point average of at least 3.00, the student is required to carry out supervised research and complete a thesis in at most two successive semesters. At the discretion of the Institute, this period may be extended by one semester. The student is required to pass an oral examination after the thesis is submitted for approval.

Students with backgrounds in Geodesy and in Geophysics, in Geology and particularly in Physics, in Mathematics and in Computer Engineering may apply to M.Sc. program. However, students without a background in Geodesy and in Geophysics may be allowed to extend their course work to three semesters, taking complementary courses in related fields with the approval of advisor.

DOCTOR OF PHILOSOPHY PROGRAMS

Graduate programs leading to the degrees of Doctor of Philosophy in Geodesy, Geophysics and Earthquake Engineering include (a) a minimum number of 24 credits of course work to be completed in at most four successive semesters, and (b) a dissertation to be completed in at least four at most six semesters following the completion of the course work.

The minimum number of credits of formal course work is made up of elective courses, at the discretion of the particular program in which the student is registered. Since a Ph.D. program is essentially the pursuit of individual interest in a specific professional field, the course work is planned under the guidance of an advisor to fit each student's specific objectives and needs. The 24 credits of course work should normally comprise 600 level courses; however, 400 and 500 level courses without credit, a maximum two 500 level courses with credit, may be included in the program by the approval of the advisor.

The students without an M.Sc. degree from Bogazici University must take at least two 500 or 600 level courses in addition to their regular Ph.D. program.

Upon completion of course work with a grade-point average of at least 3.20, the student is required to pass a qualifying examination. Subsequently, the student can start dissertation work under the supervision of an advisor appointed by the Institute.
The degrees of Doctor of Philosophy is conferred on candidates who have demonstrated general proficiency and high attainment of knowledge and competence in their special field of study, as well as capacity to carry out an independent investigation as evidenced by presentation of an acceptable dissertation embodying the results of original research. The degree requirements are completed on passing an oral examination.
