Definition & Meaning
Locating the epicenter in Earth science refers to the process of determining the point on the Earth's surface that is directly above the focus of an earthquake. The epicenter is crucial for understanding the earthquake's impact and for emergency response. It is identified using seismic data collected from various seismograph stations that measure the arrival times of seismic waves generated by the earthquake.
The epicenter is typically expressed in geographic coordinates, including latitude and longitude, allowing for precise mapping and analysis. Understanding the epicenter's location helps in assessing the potential damage to nearby areas and planning for disaster response.
