Only primary waves travel thought the earths interior because S waves cannot travel through the liquid portion of Earths interior and P waves can. Whoever you are, you were just schooled by an eighth grader =)
Primary Waves, Secondary Waves, and Surface Waves.
P or primary wave, S or secondary waves, L as in something waves
The waves that radiate out from an earthquake's epicenter and move side to side are called secondary waves, or S-waves. These waves are a type of seismic wave that travels through the Earth and are known for their shear motion, which causes the ground to shake laterally. S-waves can only travel through solid materials and are slower than primary waves (P-waves), which are compressional.
P-waves (primary waves) are compressional waves that travel faster than S-waves (secondary waves), which are shear waves. This difference in speed allows seismologists to determine the epicenter of an earthquake by analyzing the time difference between the arrival of these two types of waves at seismograph stations. By measuring the time interval between the arrivals of P-waves and S-waves, the distance to the epicenter can be calculated, enabling the pinpointing of its location.
It's primary succession!
The two types of waves used to predict the location of an epicenter are P-waves (primary waves) and S-waves (secondary waves). P-waves are the first to arrive and can travel through both solids and liquids, while S-waves arrive second and can only travel through solid material. By analyzing the arrival times of these waves at different seismograph stations, scientists can triangulate the location of an earthquake's epicenter.
P-waves (Primary) and S-waves (Secondary). Using the difference in time between the arrival of P- and S-waves, you can then determine the distance from the epicenter. Once you've determined the distance from the epicenter of three different stations, you'll be able to triangulate the epicenter (the point where all three circles cross).
Primary (P) and Secondary (S) waves
It certainly is. The point on the surface where the earthquake starts is the epicenter, located directly above the earthquake's focus point. The land nearest to the epicenter takes the most impact as the primary and secondary waves move outward and gradually weaken. Assuming that all buildings are the same, the buildings closest to the epicenter will always take the most damage.
Primary waves, Secondary waves, and Seismic waves
P waves, also called primary waves, are the first waves to be registered on a seismograph. The S waves, or secondary waves, are the second and slower wave to register on the seismograph. When locating an earthquakes epicenter seismologists take the first reading of the P wave, and then take the reading from the S wave. At the station of where the earthquake was recorded, seismologists draw a large circle from where the earthquakes epicenter could be. TO exactly located the earthquakes epicenter there needs to be at least 3 dfferent staions where the earthquake hit to determine its epicenter using the S and P time interval.
Twice as long. The interval between the arrival of the primary and secondary waves doubles with every doubling of the distance from the epicenter due to the different velocities of the waves.
Primary Waves, Secondary Waves, and Surface Waves.
Primary (P) waves : Primary waves, the fastest wave sent , come from the focus not the epicenter. (S) waves : Secondary waves, the second fastest wave sent out by an earthquake, it comes from the focus also.
Scientists use seismic waves to find an earthquake epicenter. By analyzing the arrival times of primary (P) and secondary (S) seismic waves at different seismic stations, scientists can triangulate the epicenter of the earthquake.
To locate an earthquake's epicenter using triangulation with three seismographs, first, each seismograph records the time it takes for seismic waves to reach it. By calculating the difference in arrival times of the primary (P) and secondary (S) waves, the distance from each seismograph to the epicenter can be determined. Each seismograph provides a circular area around it, with a radius equal to the calculated distance. The epicenter is located at the point where all three circles intersect.
