How to Build Earthquake-Resistant Data Centers
Earthquakes can disrupt data centers, leading to downtime and data loss. Building earthquake-resistant data centers ensures operations stay uninterrupted during seismic events. Here’s how:
- Follow Seismic Standards: Use IBC and ASCE-7 guidelines for structural safety.
- Reinforce Structures: Install base isolation systems, moment-resisting frames, and reinforced walls.
- Protect IT Equipment: Use shock-absorbing mounts, flexible connections, and secured cabinets.
- Choose the Right Site: Assess geological risks like fault lines and soil stability.
- Test Resilience: Perform shake tests and simulations to confirm earthquake readiness.
- Plan for Emergencies: Use early detection systems, redundant power, and cooling systems.
Example: NTT’s SV1 data center in Silicon Valley uses base isolators to reduce seismic motion by 60%, ensuring safety and operational continuity.
Investing in seismic resilience involves strong structures, protecting critical systems, and ongoing maintenance to prevent service interruptions during earthquakes.

Principles for Building Earthquake-Resistant Data Centers
Creating earthquake-resistant data centers involves following specific engineering guidelines to maintain structural stability and keep operations running smoothly during seismic events. These principles are key to modern data center design.
Seismic Standards and Certifications
Data centers must align with the International Building Code (IBC) and ASCE-7 standards. These regulations define how buildings should be designed and constructed to handle seismic activity.
| Design Aspect | Requirements | Purpose |
|---|---|---|
| Building and Equipment | IBC and ASCE-7 Guidelines | Ensures structural durability and proper installation |
| Safety Systems | Local Building Codes | Shapes the design of emergency systems |
By starting with these standards, data centers can incorporate advanced reinforcements to better handle earthquakes.
Structural Reinforcement Methods
To resist seismic forces, data centers use advanced reinforcement techniques. These include:
- Base isolation systems to absorb ground motion.
- Moment-resisting frames for added lateral stability.
- Reinforced walls to evenly distribute seismic forces.
Protecting IT Equipment and Non-Structural Components
Ensuring the safety of IT systems and other components is just as important as securing the building itself. Key measures include:
- Shock-absorbing mounts to shield equipment from vibrations.
- Flexible connections to maintain system functionality.
- Secured cabinets to prevent movement or tipping.
- Reinforced cable management to maintain connectivity.
Together, these measures create a robust approach to earthquake resilience, safeguarding both the structure and the critical systems inside. This sets the stage for the detailed design and construction processes discussed in the next section.
Steps for Designing and Building Earthquake-Resistant Data Centers
Choosing a Site and Assessing Risks
Building an earthquake-resistant data center starts with selecting the right location. Conducting a detailed geological assessment helps pinpoint seismic hazards and evaluate soil stability. For example, NTT’s SV1 data center underwent a thorough site evaluation to ensure it could withstand seismic activity.
Here are some key components of site assessment:
| Assessment Component | Purpose | Key Considerations |
|---|---|---|
| Geological Surveys | Identify fault lines and analyze soil | Liquefaction risks, bedrock depth |
| Historical Analysis | Review previous seismic activity | Frequency and magnitude of past earthquakes |
| Site-Specific Studies | Assess local ground conditions | Ground acceleration, amplification factors |
Once the risks are identified, incorporating advanced seismic technologies becomes the next step in protecting the data center.
Seismic Isolation and Damping Technologies
"All providers in the Santa Clara region build data centers to withstand earthquakes, but our base isolation design goes a step further", explains Brittany Miller, Vice President of Construction and Design for NTT.
Seismic isolation systems, like base isolators, triple-friction pedestals, and viscous dampers, are designed to absorb and control seismic energy. For instance, the base isolators used in NTT’s SV1 allow horizontal movement during an earthquake, reducing the stress on the structure.
Testing and Confirming Seismic Resilience
To ensure the data center meets the highest standards, rigorous testing is required. Achieving a Zone 4 Seismic Rating – the top standard under IBC and ASCE guidelines – demands thorough verification.
Testing methods include:
1. Full-Scale Shake Tests
These tests simulate real earthquakes to check the structural integrity and performance of equipment.
2. Computer Simulations
Engineers use simulations to predict how the building will behave under different seismic conditions.
3. Certification Process
This involves detailed analysis and documentation to confirm compliance with seismic safety standards.
Regular testing and monitoring are crucial for maintaining the data center’s resilience over time. Continuous evaluation ensures the infrastructure remains prepared for future seismic events.

Ensuring Long-Term Seismic Resilience
Emergency Systems and Operational Redundancy
Building seismic resilience isn’t just about strengthening structures – it also means having reliable emergency systems. Modern data centers rely on three key elements to keep operations running during earthquakes:
- Early detection systems that monitor seismic activity and send real-time alerts.
- Automated response mechanisms that protect equipment with smart shutdown processes.
- Redundant power and cooling systems to ensure critical operations don’t stop.
Regular Monitoring and Upgrades
As technology and seismic standards evolve, data centers must stay ahead by regularly updating their strategies. This involves consistent monitoring and maintenance.
Advanced Analysis Tools: Cutting-edge software is used to evaluate structural integrity, helping identify and address vulnerabilities before they escalate.
Seismic assessments, typically carried out every 5-10 years, along with predictive maintenance systems, play a crucial role in ensuring compliance with updated standards like IBC and ASCE. These evaluations incorporate the latest guidelines and focus on maintaining smooth operations through proactive measures.
With reliable emergency systems and consistent monitoring, data centers set the standard for long-term resilience in the face of seismic challenges.
