The focus and epicenter are terms used to describe the start and spread of a seismic event. Toss a pebble into a pond , the spot the pebble lands is the main energy focal point, the epicenter is the immediate surrounding area of the strongest waves, the waves become weaker as they leave this area.
What else can I help you with?
In what diection does a seismic wave travel?
Seismic waves travel in all directins radiating out from the Earthquake's epicenter and/or focus.
Is The point directly above the focus of an earthquake is called the S wave?
No, the point directly above the focus of an earthquake is called the epicenter. The S wave is one of the types of seismic waves that are generated during an earthquake and move slower than the P wave.
What happens to the energy to seismic waves at the distance from the focus increase?
As the distance from the seismic wave's focus increases, the energy of the seismic waves dissipates and spreads out over a larger area. This results in a decrease in wave amplitude and intensity as they travel through the Earth's crust. Consequently, the seismic waves become weaker, leading to a reduction in the perceived shaking and damage at greater distances from the epicenter.
What do you call the center of a seismic wave?
The center of a seismic wave is called the focus or hypocenter. This is the point within the Earth where the seismic waves originate.
Which type of wave causes the ground to shake in a motion parallel to the focus moving straight away from the epicenter?
The type of wave that causes the ground to shake in a motion parallel to the focus moving straight away from the epicenter is a primary (P) wave. P waves are compressional waves that travel through the Earth and are the fastest seismic waves. They are the first to be detected by seismographs during an earthquake.
The point directly above the focus of an earthquake is called the S wave?
This statement is incorrect. The point directly above the focus of an earthquake is called the epicenter, not the S wave. S waves are one type of seismic wave that travel through the Earth's interior during an earthquake.
How is the distance between the seismic station and the earthquake epicenter determined?
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
How is the distance between a seismic station and the earthquake epicenter is determined?
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
What seismic wave is the starting point?
focus
How do you figure out the distance of an epicenter?
The distance of an epicenter from a seismograph station can determined by the time it takes for the seismic waves to reach each station. You need at least 3 seismic stations to record the event to determine this. The time taken for each seismic station to resisted the event will be different as they are different distances from the epicenter. The distance to the epicenter can then be calculated for each station and a epicenter can be determined by a triangulation from all stations that have registered the event.
How does a seismic wave relate to an earthquake?
A seismic wave is a wave of energy that travels through the Earth after an earthquake occurs. These waves are responsible for the shaking and vibrations felt during an earthquake. Scientists use the study of seismic waves to understand the properties of the Earth's interior and to locate the epicenter of an earthquake.
What is the definition of seismic wave?
Seismic Waves - are mechanical vibrations that occur inside the Earth caused by the breaking of rocks.
