Earthquake Epicenter Distance Calculator — science and physics formula calculators
The Earthquake Epicenter Distance Calculator estimates how far a seismic station is from an earthquake epicenter using the time gap between the arrival of P-waves and S-waves. It is a quick classroom and field aid for understanding how seismologists locate quakes. Enter your observed arrival-time ga

About this tool
What Is Earthquake Epicenter Distance Calculator? Earthquake Epicenter Distance Calculator is a browser-based tool for Estimate epicenter distance from the P-wave and S-wave arrival gap. This guide explains the result, the calculation or processing method, and correct usage. Calculation or Processing Method Enter the arrival-time difference from one station. A true epicenter requires readings from at least three stations and triangulation. Formula or method: Epicenter distance is approximated from the P–S arrival gap multiplied by a calibrated wave-speed factor.
