Scientist use triangulation method to locate the epicentre of an earthquake from the data collected from Seismograph.
<u>Explanation:
</u>
The seismic data from three different location is collected to locate the intersect point as the epicentre point to be determined. Each earthquake is recorded in seismogram in different location.
A seismogram is the output from a graph called seismograph, which is used to determine the epicentre of an earthquake. There are two waves namely <em>P-waves or Primary waves and</em> <em>S-waves or secondary waves </em>that are considered while finding the epicentre of an earthquake.
With the seismogram, P-waves appears first before S-waves, since they travel faster through three states of matter. Thus, data from seismograph is used for locating “epicentre of an earthquake”.

Answer:
circumference of Nearth = 27692.30 km
Explanation:
we will apply here Eratosthenes logic that is here in this problem
near the sun is straight overhead at nyene and at same time that is ( 90-77 ) = 13° from zenith at the Alec town
and here 2 city 1000 km apart
so by Eratosthenes relation is
1000 = 
× circumference of Nearth
circumference of Nearth = 1000 × 
circumference of Nearth = 27692.30 km
