Galperin vs Orthogonal Seismometer Configurations: What’s the Difference and Why It Matters?
In seismic monitoring, triaxial seismometers are essential tools that capture ground motion in three dimensions. But not all triaxial sensors are designed the same way. Two dominant configurations exist: the…
Generating Fragility Curves for Seismic Risk Assessment
In the field of performance-based earthquake engineering, fragility curves are indispensable tools. These probabilistic functions describe the likelihood that a structure or component will exceed a certain damage state when…
🌍 Understanding P-Waves and S-Waves: Earth’s Early Earthquake Messengers
When the Earth rumbles, seismic waves are the carriers of its message — rippling through the ground, shaking buildings, and providing valuable insight into the structure of our planet. Among…
Tired of Low-Frequency Noise Harassment? QuakeLogic Has the Solution.
If you've ever been bothered by a deep, persistent rumble in your home—something you feel more than hear—you're not alone. Across the country, families are reporting a disturbing rise in…
Calculating Background Seismic Noise Levels: A Step-by-Step Guide
Understanding background seismic noise levels is crucial for assessing the suitability of a site for seismic monitoring and instrumentation. Background noise analysis helps identify optimal locations for seismic sensors and…
Standard vs. Compact Broadband Seismometers: Choosing the Right Sensor
Seismic monitoring requires precise, reliable instrumentation capable of detecting and recording ground motion with high fidelity. Two popular categories of seismometers in modern applications are Standard Broadband Seismometers and Compact…
Generating Noise Inputs for Shake Table Testing
Shake tables are widely used in structural and mechanical engineering research to simulate dynamic loads, including earthquakes, vibrations, and random noise inputs. One common requirement in laboratory testing is generating…
Ergodic vs. Non-Ergodic Models in Ground Motion Modeling
1. Ergodic Models An ergodic model assumes that spatial variability in ground motion is equivalent to temporal variability. In other words, it treats the variability of ground motions across different…
