EARTHQUAKE EFFECTS ON STRUCTURES Dr. G. P. Chandradhara Professor of Civil Engineering S. J. 5 Faults & Earthquakes • Earthquakes represent the vibration of Earth because of movements on faults. A fault is a crack in rock ... 3. It is this property of S waves that led seismologists to conclude that the Earth's outer core is … The surface of the Earth is made up of tectonic plates that lie beneath both the land and oceans of our planet. Down movement (Normal faulting) – Right now I will demonstrate down movement. Larger earthquakes tend to shake longer and harder and therefore cause more damage to structures1. Recommendations regarding restrictions on openings, provision of steel in various horizontal bands and vertical steel at corners and junctions The type of earthquake depends on the region where it occurs and the geological make-up of that region. • Earthquake may have caused partial collapse, but building remainder may be modeling earthquake shear sources taking into account Vp ~ 3 Vs. Also, the periods of S-waves are longer, at least by a factor of 3, than those of P-waves due to differences in wave propagation velocity. Demonstrate the types of faults with hand movements. (slide 14) A 2:50- minute video called Earthquake Waves is a NASA SciFi segment that explores the different types of waves that earthquakes create through the use of animations and a slinky. distance relative to the other earthquake types. ; C. Cryoseism, a seismic event that may be caused by a sudden cracking action in frozen soil or rock saturated with water or ice This energy are in the form of kinetic or strain energy. An earthquake occurs when Earth shakes because of the release Earthquakes are always linked with death and destruction. • Normal and reverse faults are types of dip-slip faults. The guide contains links to TOTLE Introduction to Plate Tectonics and Earthquakes teaching resources and a table of contents of teaching resources on this topic. Damper is basically a device which dissipate kinetic energy. An S wave is slower than a P wave and can only move through solid rock, not through any liquid medium. Blind thrust earthquake, an earthquake which occurs along a thrust fault that does not show signs on the Earth's surface. ... to types of faulting. The other type of earthquake is the artificial or man-made quake. The rippling effect is what causes the rapid and violent vibration of the earth surface – earthquake, shaking and tearing everything on it including the … We have already seen the types of volcanoes. 10(Special Issue 1), 1002-1015 (2015) Types of Dampers and their Seismic Performance During an Earthquake ALIREZA HEYSAMI Master Student of Structure, Jahad Daneshgahi Khuzestan University, Ahwaz, Iran. Some basic terminology STRIKE – a horizontal line along the direction of a fault plane. Once students have observed the fault blocks, compare and contrast the types of faulting. For better understanding of all the possibilities of earthquake risk reduction, it is important to classify them in terms of the role that each one of them could play. • Faults can be identified by the offset of rock layers on either side of the fault surface.
