Calculate Epicenter Distance



Formula

The formula to calculate the Epicenter Distance (ED) is:

\[ ED = (S - P) \cdot 8.4 \]

Where:

Epicenter Distance Definition

The epicenter distance is the distance from a seismic station to the epicenter of an earthquake. It is calculated based on the difference in arrival times of the first shear wave (S-wave) and the first compressional wave (P-wave). This distance helps in locating the epicenter of the earthquake and understanding its impact.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Epicenter Distance (ED):

\[ ED = (30 - 20) \cdot 8.4 = 84 \]

The Epicenter Distance (ED) is 84 km.
