Question

Two different recording stations have found that they had the same value for ΔT after an earthquake. If this is all the information they have so far, what can they conclude?

Answer 1

Answer:

The epicenter is the same distance from both recording stations

Explanation:

ΔT is the time between anomaly occurrence and the origin time of the earthquake.

Now, we are told both stations had the same value for ΔT.

This means that their points on the earth's surface which vertically above the focus of the earthquake is the same and thus we can conclude that the epicenter is the same distance from both stations.
