National Seismic Networks
Build a country's seismic monitoring infrastructure from the ground up—in months, not decades. Grillo has deployed national-scale networks in Mexico, Puerto Rico, and Haiti with UNDP, USAID, and IDB.

Monitor shaking or slow displacement with connected instruments designed for remote deployment.
Grillo Slide
Proven intermittent-monitoring principles in a smaller, lower-cost base-to-many RTK network. One base serves many rovers, backhaul is shared, and integrated solar power means the network is installed once and left in place.
- Triple-band RTK GNSS for centimetre-level positioning
- Integrated solar power and battery management — no external power system
- Shared cellular backhaul across the whole network
- Compact displacement records or optional raw GNSS observations
Grillo Pulse
Professional seismic monitoring where infrastructure ends. The Pulse combines a geophone and MEMS accelerometer in a single node — covering everything from microseismic events to M7+ without saturation, with nanosecond GPS timing and direct integration into SeisComP, Earthworm, or Grillo Cloud.
- No saturation — dual sensors cover weak motion to strong motion in one unit
- No infrastructure — solar, LTE, and GPS onboard; deploy anywhere
- No lock-in — streams directly to your existing seismic network
- No compromises — 32-bit ADC geophone + 20-bit MEMS, IP68, -20°C to +60°C
Grillo One
The urban strong-motion node built for scale. Tiny, low-power, and fully open source — the Grillo One is designed to be deployed in the hundreds across city infrastructure, buildings, and existing seismic networks. No digitiser, no proprietary lock-in, no compromises on data sovereignty.
- Built for density — 20g PCB fits anywhere; deploy across entire cities or building portfolios
- Fully open source — hardware, firmware, and software on GitHub; audit, modify, own it
- No lock-in — integrates directly with SeisComP, Earthworm, or your own pipeline
- Strong motion focused — 20-bit MEMS captures everything from felt earthquakes to M7+
Grillo Cloud
Manage your entire seismic sensor network from one dashboard. Seismic data streams directly to your on-premise servers in standard formats. Add SISTEM if you want Grillo to run automated earthquake detection and early warning alerts on your behalf.
- Connect any sensor type
- Real-time network health monitoring
- Data routed to your on-premise servers
- Optional: SISTEM automated detection & EEW
One approach. Different kinds of movement.
Whether you need continuous seismic waveforms or scheduled displacement measurements, Grillo's connected hardware is designed for field deployment.
Earthquake Early Warning
Receive crucial seconds of warning before shaking arrives. SISTEM detects earthquakes and delivers alerts in real-time. Proven to outperform Mexico's government EEW system (SASMEX) in detection speed.
Rapid, Remote Deployment
Deploy sensors in days, not months. Solar power and LTE cellular connectivity support fault lines, volcanoes, slopes, mine sites, and other locations beyond fixed infrastructure.
Full Network Monitoring
Monitor sensor and GNSS networks from a single dashboard. Track device health, battery levels, timing, connectivity, fix quality, and data quality from anywhere.
Automated Event Detection
SISTEM combines STA/LTA algorithms with GAMMA machine learning for automated event detection, cataloguing, and magnitude calculation—in real-time.
Your data, in useful forms
Stream seismic data in standard formats or use compact displacement records and optional raw GNSS observations. No lock-in. You control your data pipeline.
Or Let Us Run It For You
Don't want to manage your own processing? Add SISTEM and Grillo handles automated earthquake detection, event cataloguing, and real-time alerts—the same stack powering our EEW deployments in Mexico and Haiti.
Deployed Globally. Proven in the Field.
From national earthquake warning systems to university ground-displacement research, Grillo works with teams measuring movement in challenging environments.
Earthquake Early Warning Systems
Working with UNDP, USAID, and national governments to deploy first-of-their-kind EEW systems. Haiti's Caribbean-first system. Puerto Rico's 100+ sensor network. Mexico's proven, peer-reviewed deployment.
