How can some of the impacts of earthquakes be reduced?
A
by building structures that can sway with the motion
B
by building structures that do not move with the motion
C
by using satellites to monitor warning buoys in the ocean
D
None of the above
Explanation: 

Detailed explanation-1: -Earthquake-resistant designs typically incorporate ductility (the ability of a building to bend, sway, and deform without collapsing) within the structure and its structural members. A ductile building is able to bend and flex when exposed to the horizontal or vertical shear forces of an earthquake.

Detailed explanation-2: -Anchor large appliances to walls using safety cables or straps. Install ledge barriers on shelves and secure large, heavy items and breakables directly to shelves to keep them from falling. Install latches on drawers and cabinet doors to keep contents from spilling. Anchor filing cabinets and televisions to walls.

Detailed explanation-3: -Conventional buildings shake with the ground in an earthquake. They may sustain structural damage but are designed to remain standing. The stronger the earthquake, the more the building moves in response.

Detailed explanation-4: -Earthquake causes shaking of the ground. So, a building resting on it will experience motion at its base. From Newton’s First Law of Motion, even though the base of the building moves with the ground, the roof has a tendency to stay in its original position.

Detailed explanation-5: -It is by reinforcing their structures. To resist crashes, constructions must reorganise the energy that travels through them during earthquakes. You can use cross braces and shear walls for building earthquake resistant buildings. Moment-resisting frames, and diaphragms are also important to strengthening a building.
