Question

Imagine that you are planning to conduct field work and need to record earthquakes. What is the minimum number of seismometers you will need in order to locate the earthquakes?.

Answer 1

Three seismographs

Step-by-step explanation:

Three seismographs are needed. A circle is drawn from each of the three different seismograph locations, where the radius of each circle is equal to the distance from that station to the epicenter. The spot where those three circles intersect is the epicenter (Figure 13.12).
