The subject focuses on the understanding of dynamic effects that are transferred from the geo-logical environment to the engineering structures. The students are getting familiar with geo-physics, rock stress and its interpretation and graphic representation, local and world-scale (Word Stress Map). The deformations caused by seismic waves in igneous, metamorphic and sedimentary rocks also form part of the subject, as well as deformations caused by historic earthquakes. A main topic is the understanding of the Earth’s structural geology and seismicity with special emphasis on the Carpathian basin. The lectures will help in learning the detection methods of seismic waves and acquire the information content of the seismograms. By complet-ing the course the students will able to determine the parameters that are necessary for appro-priate seismic design. Engineering seismological approach will help the students to place the structures in the geological environment allowing the minimal risk and reducing the cost by proper seismic design.

Lectures, communication in written and oral form, use of IT tools and techniques, task solved independently and in groups as well, work organization techniques.

2023/2024 semester II

The assessment of the learning outcomes specified in clause 2.2. above, and the evaluation of student performance occurs via tests, homework assignments.

Evaluation form	Abbreviation	Assessed learning outcomes
1. midterm test	MT1	A.1-A.5; B.1, B.2, B.6; C.2, C.4; D.3
2. midterm test	MT2	A.6-A.10; B.5-B.8; C.2, C.4; D.3
1. homework	HW	A.1-A.10; B.1-B.9; C.1-C.4; D.1-D.4

A szorgalmi időszakban tartott értékelések pontos idejét, a házi feladatok ki- és beadási határidejét a "Részletes féléves ütemterv" tartalmazza, mely elérhető a tárgy honlapján.

Abbreviation	Score
MT1	40%
MT2	40%
HW	20%
Sum	100%

The midterm test is failed if the sum points of the two tests are less than the 50% of the obtaina-ble points. In case of the homework to reach the 50% of the points is also required.

There is no signature for this subject.

Determination of the final grade is according to the below described considerations:
There is no minimum requirement for the midterm tests separately; the sum results of the two midterm test have to reach at least 50% of the obtainable points.
The final grade is the average value of the result of the two midterm test and the homework weighted according to the clause 3.3.

Grade	Points (P)
excellent (5)	80<=P
good (4)	70<=P<80%
satisfactory (3)	60<=P<70%
passed (2)	50<=P<60%
failed (1)	P<50%

1) There is no minimum requirement for the individual midterm tests therefore it cannot be retaken separately.
2) Homework – after the payment of the fee given in the regulation – can be submit with delay until 16.00 or in electronic format until 23.59 of the last day of the completion week.
3) The submitted and accepted homework can be corrected without any fee until the dead-line described in the point 2.
4) The two midterm test can be retaken in merged form in the completion week free of charge. In case of correction the better result will be taking into account from the new and previous results.
