3-component Seismograms-Capturing the motion of an earthquake. (Educational)

www.iris.edu/earthquake for more animations.
Modern seismometers include 3 elements to determine the simultaneous movement in 3 directions: up-down, north-south,and east-west. Each direction of movement gives information about the earthquake. This animation shows both the movement of the three basic waves (P, S, and surface) and the effect of the waves on a building. The three seismograms produced by a modern seismograph station show that the P wave is more visible on the vertical component and the S wave amplitude is larger on the horizontal components.
We emphasize that seismic waves traveling away from an earthquake occur everywhere, not just at seismic stations.

best explanation

[@MohsenBabazadeh]

Love your informative videos. Keep up the good work!

[@PETERPARKER-cy9im]

Nice, smooth and comprehensive flow of explanation. Like it

[@mdong1033]

Thx! Trying to do my homework rn. This helped a lot.

[@saarfietst5842]

nice animations, but please a please: captioning (I am deaf, and autogenerated captioning yields strange results)

[@IRISEarthquakeScience]

We cleaned up the auto-generated captioning. Thanks for catching that.

[@lllazarrr]

Very clear explanation, well done!

[@civilengineeringstudy]

Beautifully explained.

[@meongcraft380]

Thanks for telling us, very educational and help me a lot

[@SimplySinging]

Anonymous! And it helped me a lot

[@victimboy7765]

i love you and your explanation

[@krocksmesses4654]

so why the P wave arrival time can have both positive amplitude interpretation on seismograph?

[@SB-dg4xt]

感谢分享

[@sowmyagoud6889]

So, all waves will reach the surface and cause shaking 3 times. Body waves(P and S) also come to the surface. How can this relate to the statement ” the body waves interact with the surface rocks and generate new set of waves called server space"?

who else is watching this for school

[@jjhansen5695]

i am becuse pog

[@dahoodedcheese1968]

facts my boy we watching them quality 2017 earthquake vids for science

[@kAlhooti1]

nice

[@福政幸男]

これって、三次元垂直水平振幅計測出来るってことか!

[@peterthomas986]

It looks like a bush turkey on ROIDS!

[@peterthomas986]

I agree

[@peterthomas986]

I also agree
