That would depend on how far away it was in the first place. Just use the formula:distance = time x speed
Or, solving for time:
time = distance / speed

The time it takes for a seismic wave to reach a receiving station depends on the type of wave. For example, primary waves (P-waves) travel at speeds of about 5-8 km/s in the Earth's crust. If we assume an average speed of 6 km/s, it would take approximately 60 seconds for the wave to cover 360 km.
S-waves travel at an average speed of about 3.5 kilometers per second. To calculate the time it takes for an S-wave to travel 3200 km, you would divide the distance by the speed: 3200 km ÷ 3.5 km/s, which equals approximately 914.3 seconds. Therefore, it would take roughly 15.2 minutes for the S-wave to reach the seismic station.
The time it takes for wave A to reach a station depends on the distance between the source of the wave and the station, as well as the speed of the wave. Generally, this can range from a fraction of a second to several minutes for seismic waves, for example.
P-waves are the first seismic waves to arrive at a seismograph station.
The distance of an epicenter from a seismograph station can determined by the time it takes for the seismic waves to reach each station. You need at least 3 seismic stations to record the event to determine this. The time taken for each seismic station to resisted the event will be different as they are different distances from the epicenter. The distance to the epicenter can then be calculated for each station and a epicenter can be determined by a triangulation from all stations that have registered the event.
At least three seismic stations are needed to locate an earthquake's epicenter using the triangulation method. By measuring the time it takes for seismic waves to reach each station, scientists can pinpoint the epicenter where the three circles intersect.
Technically you just need one, but the more there are, the easier it is to locate the epicenter of the earthquake. The reason for this is that based on the timing of each of the three seismic waves that reach the station, the station can calculate a radius all around the station. So picture a circle with what the radius is around the station, another station will do the same thing, and there HAS TO BE an intersection of these circles somewhere, so that narrows down the location of the epicenter. Hope this makes sense.
The time it takes for a wave to reach a station depends on the wave's speed and the distance from the wave's source to the station. You can calculate the time by dividing the distance by the wave's speed (time = distance/speed). For example, if a wave travels at 300 meters per second and is 900 meters away from the station, it would take 3 seconds to arrive.
Seismic stations may not record every earthquake due to factors such as distance from the epicenter, where smaller quakes may not generate enough energy to reach the station. Additionally, technical issues like equipment malfunctions or maintenance may prevent data collection. Environmental factors, such as noise from human activity or natural disturbances, can also interfere with the ability of the station to detect seismic waves. Finally, some earthquakes occur in remote areas with limited station coverage.
You would use the arrival time of the seismic waves at the station and knowledge of the wave velocities in various materials. By measuring the time it takes for the waves to reach the station and knowing how fast they travel through different types of rock, you can calculate the distance they have traveled from the origin.
Gallions Reach DLR station was created in 1994.
