<h3>What is an epicenter on the map?</h3><h3 />
- Epicenter is defined as the point directly at the position on the Earth's surface, where the earthquake started. These are represented by the stars on the map.
- A seismograph is an instrument used to measure the motion of the ground during an earthquake.
- The circles on the map show the effect of the earth or the waves that transmitted to which regions. The magnitude can be measured by the Richter scale.
