HELP EARTH QUAKE QUESTION !! please help!!! ill give you 5 stars!!?
assume an earthquake wave has a frequency of 2 Hz. Seismic velocities in the rock of your area range from 1000 m/s to
10 000 m/s. construct a graph of wavelength versus seismic velocity for your area, To do this remember
velocity = wavelength x frequency
If a building is safe from earthquake damage ONLY if it is shorter that one-fifth of a wavelength, what is the largest building you can build in the area
PLEASE HELPPP!P!P!P!P!P!P!P!!P!P!PP!!
hm, i have no experience in seismology, but i may understand the issue. the graph they want will be as follows: the bottom axis is seismic velocity, from 1000 to 10,000. the vertical axis will be wavelengths, from 500 to 5000. to find your points on the graph, you divide the values on the bottom axis by 2. (for 2 Hz). the lowest will be 500. 1000m/s over 2Hz. the graph will slope up to the value of 5000. (10,000m/s over 2Hz).
so, and I’m just making a somewhat educated guess here, the largest building you can build would be 1/5th of 5000. so, maybe 1000 meters?
I’m only guessing here by using the formula you provided. I’m sure I’ll be slaughtered for this. i hope a geologist gives you a a better answer and keeps you from a big fat F on your paper.
