Epicenter Postlab – Data Table

Epicenter Postlab 1.The epicenter of the earthquake was near St. Louis Missouri.

Epicenter Postlab 2. The S-wave would arrive 260 seconds after the P-wave if the seismograph is 3000 km away from the epicenter. 260 seconds

Epicenter Postlab 3. As the distance from the epicenter increases the distance between the P-wave and the S- wave increases because the P wave is travelling faster than the S wave so the more time that passes the more distance is put between them.

Epicenter Postlab 4. The focus is the area in the lithosphere where the earthquake originated and the epicenter is the area on the earth’s surface directly above the focus.

Epicenter Postlab 5. Knowing the location of the epicenter of the earthquake helps seismologists track patterns and trends along faults. This can help them make better earthquake predictions in the future.
