Calculate the surface wave magnitude Ms for an earthquake with IMM of VII, in an area that can be approximated by a circle with radius 20 km for a site at the borders of the given isoseismal map. This site is located in the Western United States. You may use the equation given below. Compare the ensuing value with the estimates from relationships with other magnitude scales. Calculate the fault surface displacements. Assume that the earthquake mechanism is normal. M, =-1.10 +0.62 I, +1.30 -10 r, +1.62 log(r, )
Question 3 shoreline arare crest 20° tave cres 45° deep water A monochromatic wave is approaching to the beach of which the bottom contours are parallel to the shoreline. The angles of the wave crests are shown in deep water and at location A. The wave speed of this wave is equal to 6.7 ms- in deep water. (1) Determine the wave speed and wave length at location A. (2) Determine the water depth at location A.
Q#3. For Vp=5 km/s and Vs=3.5km/s, Analyse the time history of an earthquake as given in figure 2 to find: The epicentral distance in km. The size of earthquake in local magnitude ML. The origin time of the earthquake.
2- Determine the total energy of the 1999s two earthquake's Ms=7.2-November Düzce& M₁=7.4- August 1999 Kocaeli Earthquake in terms of erg. Compare the calculated total energy with the energy of the "1939 Erzincan Earthquake" with a magnitude of Ms=7.9
For an earthquake of magnitude M=7.0 and depth 25 km, calculate the peak ground acceleration at a site 50 km from the epicentre using the attenuation relationships for Europe, Japan, and western North America (randomly- oriented horizontal components). The fault mechanism is normal and the seismic waves travel through a thick layer of rock (v=780 m/sec). Compare the results with the prediction of the world-wide attenuation relationship. Plot the curve of the above attenuation relationships for M=7 and comment on the plots.
5. During the Mexico City earthquake of 1985 certain buildings collapsed, while others remained standing. What was the issue with the buildings that collapsed? How could these collapses have been avoided? 6. What are some other examples of resonance? How does resonance affect these different systems? 7. Structural engineers consult with geologists to help predict the expected frequency of earthquake motions at a given site. They use this information to then make sure that buildings on that site do not have the same natural frequency as the expected earthquake input motions to avoid setting up resonance, in which the displacements of the building are amplified. What are some different strategies you might use to change the frequency of a building? Is it better to design buildings that are stiffer or more flexible?
Two Seismographic stations A and B are located 200 km apart on level ground. An earthquake occurred between these two stations and the epicenter is located exactly on the line joining these two stations. The difference in time between P and S wave arrivals was 10 seconds at A and 15 seconds at B. Determine the location of epicenter from these two stations.
A structure weights 154 kips and has a period of 1.0 sec. The displacement in a particular earthquake is 0.6 in. What is the corresponding base shear? (There are two ways of doing this. The best is to convert D to A and multiply by the mass of the structure (W/g).
11 - Richter magnitude is based on maximum seismic amplitude recorded at a distance of 100 km from epicentre by calculating ; 93 a) the log to e base of the amplitude the log to 10th base of the amplitude the log to 10th base of the 100 km distance b) d) 10 times the amplitude
