Activity 3.4 Directions: Answer the questions directly.
1. What is the main difference between active and inactive faults?

2. How important it is to be knowledgeable about the different locations of active faults especially when building infrastructures? Explain.

3. What are the possible dangers that could be brought about by building or living near any active fault?

4. As a Grade 8 student, how would you help your neighbors to be aware of the active faults in your locality?

1. Active faults are structure along which we expect displacement to occur. By definition, since a shallow earthquake is a process that produces displacement across a fault, all shallow earthquakes occur on active faults. Inactive faults are structures that we can identify, but which do no have earthquakes.

2.It is important to divide the TITL into segments or active faults, which have individually caused an earthquake, in order to determine the magnitude of the expected earthquake.

3.

Active faulting is considered to be a geologic hazard - one related to earthquakes as a cause. Effects of movement on an active fault include strong ground motion, surface faulting, tectonic deformation, landslides and rockfalls, liquefaction, tsunamis, and seiches.

4.During an earthquake

Stay inside.

Drop under heavy furniture such as a table, desk, bed or any solid furniture.

Cover your head and torso to prevent being hit by falling objects.

Hold on to the object that you are under so that you remain covered.
