Istanbul—the largest populated city in Europe—is considered to be a likely candidate to experience a major earthquake during the next few decades. The recent earthquakes are a reminder for potential hazard.
Istanbul has a population of over thirteen million. This megacity was exposed to at least five damaging earthquakes between 15th and early 19th centuries. It is now considered likely to experience a major earthquake. Compelled by the level of seismic risk and as a result of increased awareness of the earthquake threat, preparedness of the cities infrastructure is of paramount importance.
At QuakeLogic, we create smart cities where hospitals, schools, residential stock, commercial buildings, bridges, dams, tunnels and other infrastructure are all equipped with sensors having advanced technologies. Our structural health monitoring (SHM) system powered by artificial intelligence utilizes the sensors data to create unique earthquake risk management solutions.
We provide meaningful and easy-to-understand information immediately after an earthquake. This timely and critical information helps stakeholders such as government authorities, emergency responders, disaster managers as well as building and business owners to plan their role in making the people and their structure safer.
Our mission is to ensure peace of mind for people of megacities like Istanbul after an earthquake.
We believe in resilience of infrastructure where everyone lives in a safe and sustainable environment. Together we can make Istanbul a smart city.

Executive Summary
Structural health monitoring uses sensors, data acquisition, signal processing, and engineering interpretation to track condition and detect abnormal response. This article has been expanded as an engineering resource for readers evaluating structural health monitoring concepts, instrumentation choices, and monitoring workflows. The discussion is educational and should be paired with project-specific review by qualified engineers, applicable codes, owner requirements, and equipment documentation.
Key Takeaways
- Define the engineering objective before selecting sensors, test equipment, trigger thresholds, or reporting workflows.
- Use calibrated instrumentation, documented installation practices, time synchronization, and traceable data handling where measurement quality matters.
- Interpret measured data in context: site conditions, structure type, noise environment, sampling rate, bandwidth, and boundary conditions all affect conclusions.
- Use authoritative references and project-specific criteria rather than relying on generic thresholds or unsupported performance claims.
Technical Explanation
In practical structural health monitoring work, the engineering system is more than a sensor or a test platform. A credible workflow includes the measurement objective, instrument selection, mounting or boundary conditions, sampling and timing strategy, data validation, event or response detection, engineering review, and reporting. Weakness in any part of that chain can reduce confidence in the final interpretation.
For monitoring applications, engineers should document sensor orientation, coupling, environmental exposure, dynamic range, frequency bandwidth, data logger configuration, clock synchronization, communications, and maintenance procedures. For testing applications, engineers should document input motion, fixture design, payload properties, control limits, safety interlocks, acceptance criteria, and post-test data review.
Engineering Applications
| Application | Engineering Question | Typical Evidence Needed |
|---|---|---|
| Research and education | How does a structure, component, or sensor respond under controlled conditions? | Test plan, calibrated data, input motion, boundary conditions, and repeatable observations. |
| Critical infrastructure | Is the asset response normal, changing, or potentially unsafe after an event? | Baseline data, event records, thresholds, inspection workflow, and engineering sign-off. |
| Industrial facilities | Can monitoring support operational continuity and response decisions? | Site-specific criteria, reliable telemetry, alarm logic, maintenance records, and documented procedures. |
People Also Ask
What should be specified before buying equipment?
Specify the measurement objective, frequency range, amplitude range, environment, data format, timing needs, installation constraints, reporting requirements, and applicable standards or owner criteria.
Why do references and standards matter?
They provide terminology, acceptance criteria, test methods, and documentation expectations. They do not replace engineering judgment, but they reduce ambiguity and make results easier to review.
How should data quality be checked?
Review calibration status, timing, clipping, sensor orientation, signal-to-noise ratio, environmental artifacts, data completeness, and whether the record supports the engineering decision being made.
