Starting from the beginning of an earthquake, number the steps of the triangulation process in the correct order to find the epi

center.
1.)Subtract the time of P wave arrival from S wave arrival.
2.)Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.
3.) Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
4.)See what the time difference is equal to in distance on a seismic wave chart.

Answer:

The correct order to find the epicenter is: 1, 4, 3, 2.

Explanation:

The method used to find the epicenter of an earthquake is called triangulation.

At least three different locations are taken, and the data of the earthquakes that have been occurring in them through a seismograph are used. In this way t<u>he epicenter is determined by the point of intersection. </u>

The seismograph keeps track of the time it takes for the first seismic wave (P) and the second (S) to arrive.  (1)

Once this information is obtained, it can be established how quickly they are traveling.

This is the calculation of the distance from the epicenter to each of the seismographs.  (4)

To know in which direction each wave was directed, circles are drawn around the locations of the seismograph.(3) Once that distance is obtained, the radius is calculated and once it is located where these three circles intersect, the epicenter is found. (2)

To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.

The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:

Step 1: Subtract the time of P wave arrival from S wave arrival.

Step 2: See what the time difference is equal to in distance on a seismic wave chart.

Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.

Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.

Plus, you did this under the wrong category. Next time, please select the correct subject. you have a bigger chance of your question getting answered if it is in the right category.
