Secondary waves.
Secondary waves
No, the primary (P) waves arrive first.
secondary
No. P-waves (or primary waves) are the first waves to arrive.False. P waves are the first waves to arrive after an earthquake occurs
P waves (APEX)
Rock under stress breaks at the focus, releasing energy and vibrations called seismic waves, which travel away from the focus, through Earth's interior, and across the surface. The three types of seismic waves are: Primary waves: The first to arrive at seismographs Secondary waves: The second to arrive at seismographs Surface waves: The last and most severe to arrive at seismographs
In seismology, a P-wave is a primary wave, or sometimes a pressure wave. In general, the primary wave is the fastest moving seismic wave, as it is the first to reach any detector (seismometer) set up to sense them. Use the link below for more information.
P-waves are the first seismic waves to arrive at a seismograph station.
Primary waves are called so because they are the first to arrive, and secondary waves are called so because they arrive second. Based on this logic I would say no. There is in fact a marked difference, which is used to tell how far away the epicenter is from a particular seismograph.
There are three types of seismic waves released by an earthquake. Primary waves (P waves) are longitudinal or compressional waves and travel through the Earth's interior. They are first to arrive at a seismic station (velocity 5-8 km/s). Secondary waves (S waves) are a transverse or shear wave and move at a lower speed than that of primary waves (velocity 3-5 km/s). They arrive second at the seismic station. Finally, there are surface waves which as the name suggests travel along the Earth's surface, there are two main types (the Love wave and Rayleigh wave) and these are the slowest types of seismic waves (velocity 2.5 - 4.5 km/s) and hence arrive last at the seismic station.
P waves have a higher velocity than S waves. This is known because P waves (Primary waves) arrive at recording stations faster than all other waves. S waves (Secondary waves) arrive second at recording stations.
# Types of Waves that Travel Through the Earth's Surface * P waves arrive first and vibrate energy back and forth * S waves arrive second and shake side to side and up and down * Surface waves arrive last when an earthquake has occurred, they last the longest, are the most violent from the surface
