Sensitive devices of the Seismological Central Observatory in
Finland have measured some activity in the surface of the Earth.
First calculations show that the epicenter of this small earthquake
is somewhere in Vantaa. Unfortunately the scientists don’t have
time to calculate the exact place. They would be extremely grateful
if you could help them to complete this case.
They can provide you the measures from different stations.

Time indicates the moment when the earthquake was measured at
the given station.
With the given parameters you can calculate the exact epicenter.
That is where you will find what you are searching for.
Professors at the seismological center of Finland advice you to
use the following assumptions:
- Use WGS84 standard to model the earth.
- Distance between FINES and RAF is 236.12590 kilometers
- Within this area earthquake travels on a constant
speed.
Good luck for your calculations.
