The Challenge
Geoscience Australia's earthquake monitoring depended on manual data collection from 312 remote sensors. Each collection cycle took hours, creating dangerous blind spots where seismic events went undetected until the next manual pull.
Key challenges included:
- 4+ hour average latency between sensor reading and portal update
- Inconsistent miniseed file formats across sensor manufacturers
- No fault tolerance—a single network interruption could drop days of data
- Emergency services relying on stale seismic readings for response decisions
- Sensor network growing 15% annually with no scalable ingestion path
Why It Matters
Australia records over 1,500 earthquakes per year. The Earthquakes Portal is the primary data source for state emergency services, mining operators, and critical infrastructure managers. Even a 30-minute delay in detection can compromise evacuation decisions.
Emergency Response Impact
The Earthquakes Portal serves as a primary source of seismic data for emergency services across Australia, making real-time data availability essential for disaster response.
Our Solution
Emergency services now receive seismic alerts within 8 minutes of an event, down from 4+ hours. The pipeline runs unattended across 312 sensors with 99.97% uptime over its first 18 months, processing an average of 47,000 miniseed files daily.
Collection
312 sensors polled on 5-minute intervals
Ingestion
Lambda processes ~47K files/day
Processing
Parse, validate, and normalize miniseed
Storage
PostgreSQL with time-series indexing
Publish
Portal charts and emergency alerts
Automated Data Collection
Scheduled collectors poll 312 sensors on 5-minute intervals, eliminating manual retrieval and its 4-hour latency.
AWS Lambda Processing
Serverless functions process ~47K miniseed files daily, scaling automatically during high-activity seismic periods.
Fault-Tolerant Architecture
Automatic retries and dead-letter queues recovered 99.8% of dropped files during network interruptions in the first year.
S3 Data Lake
Raw miniseed archive with lifecycle policies, storing 2.3 TB of historical seismic data at $0.023/GB/month.
Sub-8-Minute Latency
End-to-end pipeline from sensor reading to portal update in under 8 minutes, down from 4+ hours.
Emergency Alert Generation
SNS-based alerts notify emergency services within minutes of detecting events above magnitude 3.0.
