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?

# volcanos and seismographs?

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.

# Is it possible to build a simple type of device for measuring earthquake magnitudes for home 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’s the accuracy of a homemade seismograph?

What is the accuracy of a homemade seismograph?

i want to make a simple seismograph for my science exhibition.

# How do I figure out how far away an earthquake is in meters given the velocity of the P and S waves?

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!
