Ensuring Safety with QuakeLogic Shake Tables

Shake tables from QuakeLogic are cutting-edge tools designed to test the structural integrity of buildings, models, and equipment under simulated earthquake conditions. While these instruments are integral in advancing our understanding of seismic safety, proper precautions must be taken to ensure a safe environment for all operators and researchers.

Safety Precautions

1. Protective Gear:

  • Always wear safety glasses and gloves while operating the shake table.
  • This protective gear safeguards against potential hazards such as flying debris, sharp edges, and other unforeseen risks.

2. Keep Hands Clear:

  • Ensure that hands, fingers, and all other body parts remain clear of the shake table during operation.
  • This simple measure can prevent severe injuries due to sudden movements or pinching.

3. Warning Signs:

  • Display clear warning signs around the shake table area.
  • The signs will remind all users of operational hazards and reinforce the importance of following safety practices.

4. Mounting:

  • Securely mount the shake table to stable ground prior to operation.
  • An improperly mounted shake table can lead to unintended movement and pose serious safety risks.
  • Strong Recommendation: We strongly recommend fixing the shake table to the floor before any test begins.

Additional Safety Guidelines

5. Training and Certification:

  • Ensure that all users are trained and certified in operating the shake table.
  • Familiarity with the equipment and emergency procedures is crucial in avoiding accidents.

6. Load Testing:

  • Before testing, carefully inspect the model or equipment to be placed on the shake table.
  • Ensure that the total weight does not exceed the maximum load capacity of the shake table.

7. Emergency Stop:

  • Familiarize all users with the location and use of the emergency stop button.
  • In case of any anomaly or potential hazard, this button will immediately halt the table’s operation.

8. Inspection and Maintenance:

  • Regularly inspect the shake table for signs of wear, damage, or malfunction.
  • Perform routine maintenance to keep the table in optimal working condition.


Safety should always be a priority when working with QuakeLogic shake tables. By adhering to these safety precautions, operators can ensure a safe working environment while gaining valuable insights into the seismic behavior of various structures. Remember, safety glasses and gloves are mandatory, hands should always be kept clear, warning signs must be visible, and mounting the shake table securely to the ground is non-negotiable.

Mastering Seismic Data Accuracy: The Science Behind Seismic Corrections

Understanding and predicting seismic events with high accuracy requires not only sophisticated technology but also meticulous data correction techniques. Among these, correcting for phase errors and instrument responses is paramount in refining the data captured by seismometers. This blog delves into the essential corrections applied to seismic data, commonly misunderstood under terms like “Lippmann correction,” and explains their scientific foundation and importance.

The Essence of Seismic Data Corrections

Seismic data corrections are crucial for converting raw seismometer readings into accurate representations of ground movements. These corrections include adjusting for instrument response and correcting phase discrepancies, both of which are vital for the precise analysis of seismic data.

Correcting Instrument Response

Each seismometer has a unique response to incoming ground motions, characterized by its sensitivity across different frequencies. This response can significantly distort the recorded data by altering amplitude, phase, and frequency. The instrument response correction aims to reverse these distortions and retrieve the true ground motion:



  • a(t) is the corrected ground motion.
  • d(t) is the recorded data.
  • r(t) is the instrument’s response function.
  • The operator (*) denotes convolution, and (-1) indicates deconvolution.

This correction ensures that the data reflects the actual seismic events, free from the biases introduced by the instrument’s characteristics.

Phase Correction

Phase errors occur when there is a misalignment between the recorded seismic wave phases and their true timing. Correcting these errors involves adjusting the phase angle in the frequency domain:



  • S(f) represents the original signal in the frequency domain.
  • S'(f) is the corrected signal.
  • ϕ(f) is the phase correction needed.
  • i is the imaginary unit.
  • e stands for the exponential function.

Phase correction is critical for ensuring the temporal accuracy of seismic waveforms, which is crucial for detailed seismic analysis and reliable earthquake detection.

Why Are These Corrections Crucial?

The fidelity of seismic data directly influences the effectiveness of seismic monitoring and analysis. Here are the key reasons why applying these corrections is indispensable:

  • Accuracy: Precise corrections ensure that the seismic data truly represents the ground movements, which is essential for all further seismic analyses and interpretations.
  • Reliability: Enhanced data accuracy increases the reliability of seismic monitoring systems, crucial for predicting and mitigating seismic hazards.
  • Safety: Accurate seismic data improves the performance of early-warning systems, thereby increasing public safety and infrastructure resilience in earthquake-prone areas.
