Earthquake catalogues. Gutenberg-Richter relation, estimation of the catalogue completeness. Functions of attenuation of intensity, PGA, PGV, PGD. Dynamic factor of amplification (DAF), amplification spectra for vertically incident SH-waves. Seismic hazard and risk.
LEARNING OUTCOMES:
The course on Engineering seismology enable students to:
- Describe the typical contents of earthquake catalogues.
- Define and discuss the Gutenberg-Richter relation, and to estimate its parameters, given an earthquake catalogue.
- To estimate the catalogue completeness with respect to the smallest magnitude and/or the time interval.
- Define properties of the Poissonian process.
- Describe main factors influencing recorded strong motion at some location.
- Compute amplification spectra for given geotechnical models of soil layers.
- Differentiate between properties of soil based on the corresponding amplification spectra.
- Differentiate between the deterministic and probabilistic approach to hazard determination.
- Argue for the properties of seismic hazard as described by a given hazard map.
LEARNING MODE:
Lectures and exercises attendance, study of notes and literature. Equation derivation and example analysis.
TEACHING METHODS:
Lectures and discussion, derivation of equations. Independent solving of exercises.
TERMS FOR RECEIVING THE SIGNATURE:
The first two homework have to be positively graded and the third homework submitted. Attendance at least 70% of classes (lectures and exercises).
EXAMINATION METHODS:
Three homework assignments in the form of a written report for assessment and an oral exam. The final grade is the arithmetic mean of the grades from the homework assignments and the oral exam.
The homework assignment consists of a task that the student must solve and present the solution in the form of a written report (seminar/paper) in which the basic professional terms in the assignment, data, method and procedure (briefly) are described, the results are described with a short interpretation or discussion and an appropriate graphic representation and conclusion. The assignment is also presented orally (presentation). The assessment considers physical accuracy (the greatest weight in the assessment), the structure of the report, the presentation of results and (professional) literacy. The final grade from the homework assignments is the average of the grades from the individual homework assignments. Each homework assignment is assessed separately, and the arithmetic mean of all three assignments is taken as the homework grade. In order to be able to take the oral exam, all three homework assignments must be positively assessed.
The oral exam consists of questions in which student needs to define/describe/explain technical terms and derive equations from the course material.
