P-waves, which may also be known as primary (as they arrive travel faster than other types of seismic waves and so are recorded on a seismometer first) or pressure waves as they propagate by the compression of matter.
The P wave created from an earthquake originates from?æthe focus then travels in all the phases of matter. The wave is the first to arrive and to be recorded on?æa seismograph.

In order to write an effective report on travel tourism, the location should be well researched and the writer should be very knowledgeable about the area. Informing readers is the main focus of such a report, so it is important to give as much detail as possible about each area of interest.
The strongest shaking is towards the center of the actual earthquake which it is called the focus. The epicenter of an earthquake is the point on the Earth's surface above the focus or hypocenter which is the point within the Earth where the rupture occurs. As such the epicenter is the closest point to this and the seismic waves have had to travel through the smallest amount of material and so have undergone the least amount of attenuation (in this case attenuation is a reduction in amplitude of the seismic waves due to energy being by moving through the Earth). However as with a lot of things in Earth sciences there can be exceptions to this! This is because the amplitude of seismic waves is affected by the density (related to the level of compaction in the case of soils) of the material through which it is traveling). So a seismic wave traveling through a hard rock such as granite will have a much lower amplitude than one traveling through a softer, less dense, poorly compacted material such as a soil and so due to the higher amplitude there will be a higher level of perceived and measurable ground shaking, even an equal distances from the epicenter.
The coarse focus on a microscope is provided to move the instrument quickly to where it is nearly in focus. Some microscopes only have a coarse focus. The fine focus is used to move with slower and more precise adjustment to where the instrument is exactly in focus.
FOCUS
Seismic p
p waves
These waves are slower than those that originate at the focus.
Surface wave
The waves that are slower that those that originate at the focus are called secondary waves or S-waves. They are shear waves that are transverse in nature.
S waves shear rock back and forth as they travel through it.
where the fault is at or the epicenter which is not where the earthquake starts it is the focus where the earthquake starts
If you want to know what the name is, it is called the epicenter. If you want to know a location where all earthquakes originate, there isn't one. Earthquakes can occur along faultlines, or in the middle of a continent.
Seismic waves are the earths crust vibrating. there are two types of waves P-waves and S-waves (Primary and Secondary) Primary waves travel faster than s waves and can travel through solid and liquid, S-waves can only travel through solids
State three ideas or topics that could serve as the focus of subject matter in an artwork.
"Matter" is a possibility.
Focus an energetic wave at some matter and see what happens.
