Final answer:
Seismometers used in the triangulation method must be within 1,000 km of each other to accurately determine the location of an epicenter.
Step-by-step explanation:
Triangulation is a method used to locate the correct location of an epicenter by using seismometers. However, for accurate results, the seismometers used must be within 1,000 km of each other.For example, if we have three seismometers placed at different locations and they are within 1,000 km of each other, we can measure the arrival times of seismic waves at each seismometer. By comparing the arrival times, we can determine the distance to the epicenter and triangulate its location.Therefore, the statement is True.
