- 30. z Key Questions: Where is the epicenter of this hypothetical earthquake? What difficulty will you encounter if you only have data from two recording stations? What is the distance of the epicenter from the seismic station? What do you think is the importance of determining the epicenter of an earthquake?
- 31. z 1.Where is the epicenter of this hypothetical earthquake? Answer:Since the three circles drawn intersect in Cebu City, it is where the epicenter is 2. What difficulty will you encounter if you only have data from two recording stations? Answer: Assuming that the two circles will intersect, the circles will intersect at two points. Therefore, there will be two locations that could possibly be the epicenter
- 32. z 3. What is the distance of the epicenter from the seismic station? Answer: 9000 km 4.What do you think is the importance of determining the epicenter of an earthquake? * Answer:Locating earthquake epicenters will pinpoint which fault lines are active. Usually, the less active fault line stores great amount of potential energy that could cause major earthquake once released. Therefore, places near fault lines that remain inactive for a long period of time are due to experience a major earthquake
