Definition
An earthquake early warning system combines seismic sensors, local or network detection logic, communications, alert outputs, and response procedures to reduce reaction time where warning time is physically possible.
Engineering Problem Statement
Facilities and agencies need low-latency detection and response workflows without treating alarms as a substitute for engineering judgment.
System Architecture
- Seismic switch or accelerograph
- Edge detection or network processing
- Communications path
- Alarm, relay, or dashboard output
- Testing and maintenance procedure
How Products Work Together
QuakeLogic solution architectures should be specified as complete systems: sensors generate measurements, acquisition hardware synchronizes and stores data, communications move data to reviewers, software supports dashboards and reports, and documentation supports procurement, commissioning, and maintenance.
Selection Guidance
- Choose local switch logic for equipment shutdown or facility alarms
- Choose networked architecture when station density, communications, and governance support it
- Confirm latency, output type, and false alarm tolerance before procurement

Frequently Asked Questions
Which sensor should I choose?
Choose by measured quantity, range, frequency, accuracy, installation environment, calibration needs, and data use case.
What data acquisition hardware is required?
Confirm sensor signal type, channel count, sampling rate, timing, local storage, telemetry, power, and software compatibility.
Which communication method is appropriate?
Use wired links for controlled short runs, wireless or cellular for remote sites, and local storage where communications are unavailable or not required in real time.
