In regards to a seismograph’s location, does the p-s interval get larger or smaller with the increasing distance from the epicenter?
When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 10.5 km/s and the secondary, or S, wave has a speed of about 5.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 140 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far is the seismograph from the earthquake?
For geography homework I have to make Dominoes of Richter Scale to Seismograph. In other words I’m making it so one side of it will be a Richter measurement and the other will be the same in Seismic measurement, but I cannot find anything showing this (E.G. 6.0 On the Richter scale = Whatever on the Seismograph) someone give me a link or some help?
How is the magnitude of an earthquake recorded?
If you can answer, could you try to do it like an excellence/A+ style question, using the words ‘seismograph’ and ‘seismogram.’
Please give me at least three examples. Except for the seismograph(seismic waves), echo sounding, and geophysics.. Please give me other than that. I need it for my homework. Please.
what does a seismograph have to do with the Richter scale?
What is the amplitude (in mm) registered on a standard seismograph (same as that used by Charles Richter) of a Magnitude 5 earthquake at 200km?
I don’t even know where to start with this problem D:
My apartment has tremors and vibrations that feel like a small earthquake. It comes and goes, and my landlord and I have no idea what it is. We’ve checked with other tenants with respect to fans, A/C’s, etc. We would like to measure the vibrations and feed it into a PC so that we try and get a better understanding of thigns. Any ideas on how to do this short of buying a seismograph? It wakes me up sometimes in the middle of the night as it shakes my bed, so I would like to fix this. And no we are not thinking of calling an Exorcist.
I agree that the goal is to find the source, and we think if we can track its frequency then this would help.
There are vibration sensors, some are MEMS, and some of these are not so expensive. Would need to find a way to connect to the pc.
Seismic waves are partly reflected when they cross a boundary such as the between the solid mantle and the liquid outer core. Suppose a P wave has a constant speed of 8Km/s. 700 seconds after an earthquake near the surface, a seismograph at the site of the earthquake detect a reflected p wave . How far below the surface is the mantle-core boundary?
What two items were invented during the industrial revolution?
Typewriter and Phonograph
Cell phone and First Computer
Seismograph and Porcelain
Eye glasses and Modern Surgery
I know: the velocity of the longitudinal p-waves is 8.9 km/s, and that of the transverse s-waves is 5.1 km/s. A seismograph records the arrival of the transverse waves 73 s after the longitudinal waves arrive. How do I figure out how far away the earthquake was?
ok so i need some help regarding the island of toba weather it comes to facts or vocabuly words i know most of the basic hings already so thanks.
i aslo need as much helps as i can get regarding the inventor of the seismograph so thanks!!!!
I’m doing a project in algebra on earthquakes. I think that it might be the Richter scale and the mercalli scale. but there’s also a seismograph…so im not sure which two to use.
Yes, I know the question may seem dumb, but honestly, how would I know if I didn’t ask? Not sure if saying seismograph is proper or not.
does anyone know how to make a model of a seismograph that actually works?
and the secondary, or S, wave has a speed of about 5.46 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 83.5 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far is the seismograph from the earthquake?
What important events such as the building of the Silk Road occur during the Han Dynasty, However, I don’t want anything like an invention, such as they invented the seismograph or paper. Please list 3 or more or as many as you know. if you don’t know what i mean just give it your best shot…please i need this for a project due in a few hours.
What is the accuracy of a homemade seismograph?
i want to make a simple seismograph for my science exhibition.
The speed of longitudinal waves, called P waves, is 8000 m/s.
Transverse waves, called S waves, travel at a slower 4500 m/s . A seismograph records the two waves from a distant earthquake.
If the S wave arrives 2.0 min after the P wave, how far away was the earthquake?
If possible, I’d like the answer as well as an explanation of how to solve the problem so that I can work back through it again myself. Thanks!
I have an 04 muatang with a mach system and I want better sounding audio. No, I don’t want to drive around playing bass tracks that register on a seismograph. I just want a decent sound that is clear, not raspy or "high-pass" at any volume, and has decent AND resonable bass response. Should I just get new speakers or something else?

The distance between an earthquake epicenter and the location of a seismograph can be calculated because
1. seismographs are sensitive to directions
2. earthquake waves decay at known rates
3. shear waves will not pass through liquids
4. shear waves and compression waves travel at different speeds
I don’t want to spend a lot, well actually I wouldn’t really want to spend anything since its only a minor assignment but I really want to know how I can make a richter scale or even a seismograph. Thank you (:
When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 9.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 140 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far is the seismograph from the earthquake?

The answer for this problem is 8.8 X 10^5 m. I can’t seem to get this answer… can you tell me how you did it if you know how to do it? Thanks!
(Earthquakes question). What is the relationship of the motion on a seismograph versus the true motion of the ground where the seismograph is located?
How could someone predict the approximate location of an epicenter without a seismograph??
I had a bookmark to a real time seismograph for Southern California but I have lost it, I have searched but nothing so far.
Yes I felt that one too. Thanks to both of you for the links but the one I had was a link to the actual seismograph in real time. It was linked by a local tv station, however I guess it has been removed.
The second answer is pretty close to what I had…thank you so much.
A) When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.00 km/ s and the secondary, or S, wave has a speed of about 5.22 km/ s. A seismograph, located some distance away, records the arrival of the P wave and then, 82.5 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far is the seismograph from the earthquake?
B)The volume control on a stereo amplifier is adjusted so the sound intensity level increases from 28.7 to 56.9 dB. What is the ratio of the final sound intensity to the original sound intensity?
C)Asource is generating circular waves on the surface of a lake. The waves have a wavelength of 12.0 m and travel outward at a speed of 6.67 m/s. You are in a boat whose speed is 4.09 m/s and heading directly toward the source of the waves. What do you observe for the frequency of the waves?
what is Doppler’s Effect where you said you will observe Doppler’s effect-increase of frequency.
