epicenter
Three seismograph stations are needed to determine the location of an epicenter because each seismograph can determine distance to the epicenter but not direction. The point where the three circles intersect is the epicenter of the earthquake. +++ Focus - not epicentre, which is the point of maximum movement on the surface above the slip itself.
no
Your question is meaningless, there is either an absolute logation (x/y point) or an approximate location(near the house on the corner), there can not be an "approximate absolute" location.
Three seismic records from different locations are needed to determine the position of an epicenter because the time it takes for seismic waves to reach each location varies depending on the distance from the epicenter. By comparing the difference in arrival times of the waves at each location, scientists can triangulate the epicenter's location. This method helps provide a more accurate estimation of the epicenter's position.
The farther apart the arrival times of the different waves are, the farther away the earthquake is. :)
how do seismologist know how to find the location of a epicenter
Approximate location of what, exactly?
The location on the surface directly above the earthquake focus is called the epicenter.
yes
That would be the "epicenter".
The minimum number of seismic stations needed to determine the location of an earthquake's epicenter is THREE.
The minimum number of seismic stations needed to determine the location of an earthquake's epicenter is THREE.
The minimum number of seismic stations needed to determine the location of an earthquake's epicenter is THREE.
The map location of an earthquake is called its epicenter. This represents the point on the Earth's surface directly above where the earthquake originated.
The term defined as the exact location where an earthquake occurred is the "epicenter." It is the point on the Earth's surface directly above the location where the earthquake's energy is released.
