Direction: Write True if the statement is correct and false if it is incorrect.
11. Intensity will decrease when observed farther from the epicenter.
12. Magnitude increases while intensity remains constant
13. Both intensity 2 and magnitude 2 are considered weak vibrations of the ground and can hardly be felt by people.
14. Magnitude can be measured by an instrument while intensity is by observation.
15. Some areas nearer to the epicenter recorded lesser intensity because it is affected by other factors like population density, geology of the area and types of building constructions.
16. Fault line is a rigid section of the lithosphere that moves as a a unit.
17. An active fault is an area which had not displayed any seismic activity for more than 10,000 year, while an inactive fault displayed seismic activities over the period.
18. Marikina Valley Fault is an active fault located in the Philippines.
19. It is safe to call a fault inactive because it does not generate earthquakes for a million years.
20. Dormant faults are active fault lines that generate earthquakes from time to time.​
