Answer:
<u>Use of Triangulation, and interaction of the three circles.</u>
Explanation:
- To determine the epicenter of the earthquakes the scientist study the patterns of the waves and use this method to find the exact location of the earthquakes.
- As the earthquake has P and S waves that are released with force the distance that these waves travel are calculated with the distance of the radio waves that is reflected from least three different locations, thus it's named as triangulation all three sides.<u>
</u>
- <u>About three seismographs are used to locate these waves, along with the use of the GIS technology prediction of the faults and the future occurrence of earthquakes of done.</u>
Around rivers and lakes mainly around water.
