To construct buildings that are resistant to earthquakes, specific materials and techniques should be utilized. Here are some key points:

1. **Reinforced Concrete**: This material combines concrete with steel reinforcement bars (rebar), providing enhanced tensile strength and flexibility, essential for absorbing seismic forces.

2. **Steel Frames**: Steel is known for its high tensile strength and ductility. Using steel frames allows buildings to sway without breaking during an earthquake.

3. **Cross-Laminated Timber (CLT)**: An innovative material that provides high strength and flexibility while being lightweight. CLT can effectively absorb seismic shocks.

4. **Base Isolators**: These are not materials per se, but systems made from rubber and steel that are placed between a building's foundation and its superstructure. They allow the building to move independently of ground motion.

5. **Moment-Resisting Frames**: These frameworks are designed to flex during an earthquake, maintaining structural integrity and preventing collapse.

6. **Damping Systems**: Installed in buildings, these systems (such as tuned mass dampers) absorb and dissipate energy from seismic activity, minimizing movement.

7. **Shear Walls**: Thick, reinforced walls located strategically in a building to resist lateral forces, helping to maintain stability during seismic events.

8. **Lightweight Materials**: Using lightweight construction materials reduces the overall mass that must be supported during an earthquake, thus decreasing forces on the structure.

When planning earthquake-resistant buildings, it is important to combine these materials with sound engineering principles to ensure the structure can withstand seismic forces effectively.
