Splet01. jan. 2012 · Green is the vertical ground movement, up and down. The red line represents the seismic shaking in the North-South and the blue line in the East-West direction. The most prominent onsets are the P- and S-waves, which arrived approximately 9.5 minutes apart. However, looking at the vertical component one can clearly see more onsets (red … Splet1. Find the point where all 3 circles intersect, and you've found the earthquake's epicenter. 2. Draw circles representing the distances from at least three seismograph stations to the epicenter on a map. 3. See what the time difference …

SpletA seismograph can measure P waves, S waves, and surface waves. A seismograph works by suspending a weight from bedrock, which remains motionless during an earthquake. A rotating drum that is affixed to the moving bedrock moves as the rock moves, recording the relative displacement between the stationary weight and the rotating drum. SpletVideo lecture on wave motions and speeds of three fundamental kinds of seismic waves: Primary (P = pressure) waves; Secondary (S = shear); and Surface waves. A seismic wave is an elastic wave generated by an …

Splet06. feb. 2024 · The seismographs show that the time difference for the arrival of the P and S wave at each station is proportional to the distance of the station from epicenter. ... We can also record on the seismograph t p and t s, the P and S wave travel times. We are thus trying to find x, the distance the waves traveled. For P waves: \[x=v_pt_p\] \[t_p ... cyton money market fundSpletWhen an earthquake occurs, seismic waves, including P and S waves carry energy away from the hypocenter in all directions.
