## What is the distance between the epicenter and seismic station?

Answer Expert Verified. Answer: The distance of the epicenter from the seismic station is equal to 127 km (minimum). Using data from the seismic station, seismologists can read the 16.9 second delay time of P waves before S waves are detected.

### What is seismic epicenter?

The epicenter is the point on the Earth's surface vertically above the hypocenter (or focus), the point in the crust where a seismic rupture begins. Epicenter and hypocenter. (

**What is the formula for epicenter?**

Measure the difference in arrival times between the first shear(s) wave and the first compression(p) wave, which can be interpreted from the seismogram. Multiply the difference by 8.4 to estimate the distance in kilometers from the seismograph station to the epicenter.

**What is the difference between epicenter and seismic station?**

The distance of the seismic recording station from the epicenter of the earthquake is determined from the time difference between the first arrival of the P wave and the S wave. This is known as the SP interval.

## How big is the epicenter of an earthquake?

After looking at the Earthquake Time Travel Graph it is clear that the two curves have a difference of 5 units on the time axis at x = 3.4. Therefore, the earthquake has an epicenter distance of km or 3,400 km. Was this information helpful? What kind of problem would you like to report? Select ——> Problems viewing the page.

### How to calculate the distance to an earthquake?

Measure the difference in arrival times between the first shear(s) wave and the first compression(p) wave, which can be interpreted from the seismogram. Multiply the difference by 8.4 to estimate the distance in kilometers from the seismograph station to the epicenter. How far can a 7.0 earthquake be felt?

**How does a seismograph tell you about an earthquake?**

This combination of instruments tells a seismologist the general direction of the seismic wave source, the magnitude at its source, and the nature of the wave motion. Instruments at other stations must be used to get a precise fix on the earthquake's epicenter.

**Which wave comes first after an earthquake?**

The P wave is termed the primary preliminary wave because it is the first to arrive at a seismic station after an earthquake. It travels at a speed normally less than 6 kilometers per second in the Earth's crust and jumps to 13 kilometers per second through the core.
