Question

What starting point is to be traced to locate the epicenter of an earthquake? *

Answer 1

ANSWER & Explanation:

Measure the distance between the first P wave and the first S wave. In this case, the first P and S waves are 24 seconds apart. Find the point for 24 seconds on the left side of the chart below and mark that point. According to the chart, this earthquake's epicenter was 215 kilometers away.

Answer 2

The starting point one should trace to locate the epicenter of an earthquake is the hypocenter.

• The epicenter means a distinct location on the surface of the Earth that is usually stated as the initiation point of the Earthquake.
  
• The epicenter cannot be defined as the location of the Earthquake, it is rather the point where the imposition of the point of the Earthquake occurs.
  
• The actual point deep inside the core of the Earth, where the earthquake begins is called the Hypocenter.
  
• A hypocenter is the starting point of an Earthquake and thus needs to be traced properly.

Methods to locate starting point of Earthquake:

• The P and S waves Calculation: This involves calculating the P and S waves' time difference. After measuring the distance between the P and S waves at specific time intervals, the scientists need to calculate the amplitude of the wave that hits the strongest to locate the exact starting point of the earthquake.
  
• Seismograph Study: The scientists combine the above calculation with this instrument to get the most accurate result on the location.

Hence, the starting point one should trace to locate the epicenter of an earthquake is the hypocenter.
