In the context of the diagram you described, where circles are drawn around locations such as Portland, Salt Lake City, and Los Angeles to determine the earthquake's epicenter, the stars on the map represent the location of an epicenter. The epicenter is the point on the Earth's surface directly above where the earthquake originates (the focus). The convergence of the circles indicates where the earthquake's epicenter is likely located.
The diagram shows circles drawn by geologists trying to determine the location of an earthquake’s epicenter.
Map of the United notes. Three circles centered at Portland, Salt Lake City, and Los Angeles. The circles converge at San Francisco.
