Epicenter vs. Hypocenter: Know the Difference
By Shumaila Saeed || Published on January 14, 2024
The epicenter is the Earth's surface directly above an earthquake's origin, while the hypocenter is the actual underground location where the earthquake starts.
Key Differences
The epicenter is the point on the Earth's surface directly above the earthquake's origin, where seismic waves are often felt most strongly, while the hypocenter is located beneath the surface at the initial point of rupture.

In terms of impact, the epicenter is where the earthquake's effects are typically most pronounced and measured, whereas the hypocenter represents the true focal point of the seismic event.

The epicenter is identified using triangulation from seismograph readings, providing a surface reference point, while the hypocenter is determined through deeper seismic analysis to find its exact underground location.
