How do you understand what all the squiggly lines on a seismogram mean?
A seismogram records the ground movement caused by seismic waves from an earthquake. The squiggly lines represent the waves' amplitude and frequency. By analyzing these changes, seismologists can determine the earthquake's magnitude, location, and depth.
What state of matter do P and S waves travel through?
P waves can travel through all types of matter. S waves can only travel through solids.
What earthquake waves travel the fastest?
P waves travel faster than S waves. P waves use less energy to travel, while S waves have to use more. This is because P waves travel in a forward and back motion such as a push and pull motion. S waves have to travel in the Earth like how a snake moves, side to side. This takes more energy than just moving like a push and pull motion.
Do p waves or surface waves move faster?
No. Surface waves are slower than both P and S-waves.
Which waves are fastest?
Primary waves as they travel like a worm, compressing and then expanding
What three waves are shown on a seismogram?
The three waves that are shown on a seismogram in order are P waves, S waves, and surface waves.
After an earthquake which type of seismic wave arrives first at a seismometer?
P waves (APEX)
What is the meaning of lag- time when reading a seismogram?
Lag time in a seismogram refers to the difference in arrival times between the primary (P) waves and secondary (S) waves generated by an earthquake. This interval is crucial for determining the distance from the seismograph to the earthquake's epicenter, as P waves travel faster than S waves. By measuring the lag time, seismologists can calculate how far away the seismic event occurred, aiding in understanding and responding to seismic activity.

Waves that travel the slowest andare the last to be recorded?
Surface waves, specifically Love waves and Rayleigh waves, travel more slowly than other types of seismic waves such as P-waves and S-waves. They are the last to be recorded on a seismogram and are responsible for the majority of the shaking and damage during an earthquake due to their longer wavelengths.
How do you determine an p-s interval on a seismogram?
To determine the P-S interval on a seismogram, first identify the arrival times of the P-waves and S-waves. The P-wave is the first seismic wave to arrive, so locate its initial peak on the seismogram. Next, find the point where the S-wave arrives, which is characterized by a distinct increase in amplitude following the P-wave. The time difference between the two arrivals, known as the P-S interval, can then be calculated by subtracting the P-wave arrival time from the S-wave arrival time.
How do p waves travel?
Every direction radiating from the source. However when they enter air they cannot proceed further and when they enter liquids (e.g. water, the molten nickel-iron outer core) only the p-waves can proceed further. The direction of travel also changes over distance from the source due to refraction and/or reflection.
What state of matter do P and S waves travel through?
P waves can travel through all types of matter. S waves can only travel through solids.
Do waves travel faster than S waves?
no p waves travel faster than s waves
Do earthquake P-waves travel in straight lines?
Earthquake P-waves don't travel in straight lines, they travel in like a circle after the earthquake has struck. These P-waves arrive first during an earthquake.
Do p waves or surface waves move faster?
No. Surface waves are slower than both P and S-waves.
