Sensor networks
Low-cost instruments hosted by the people they protect, observing the ground, the coast and the air at a density no single institution could build alone. Live today: GeoShake, our earthquake network.
The first program
Sensory Earth Intelligence Systems
Sense the Earth.
Protect its people.
Planet-scale sensing for natural hazards: dense, affordable, citizen-hosted networks and the early-warning intelligence behind them. Earthquakes first, through GeoShake.

01 - Mission
A sensor in every community.
Most of the planet is still unobserved at the scale that matters. We are changing that with low-cost stations hosted by the people they protect, starting with earthquakes.
How the network works- $15-50k
Cost of a conventional seismic station. They typically stand 30-60 km apart, leaving whole towns between them unobserved.
- 40%
Share of countries that still report no multi-hazard early warning system. The UN’s Early Warnings for All initiative aims to cover everyone by 2027.1
- $224bn

02 - What we do
Instruments. Intelligence. Partnership.
Sensory Earth builds the sensors, runs the platform that turns their readings into warnings, and works with the institutions that can carry dense observation to every hazard and every region.
ii
Data & early warning
The platform behind every network: stations cross-check one another, confirmed events reach phones, buildings and infrastructure within seconds, and verified data is published through an open API.
How it worksiii
Research & partnerships
With universities, civil-protection agencies, insurers and infrastructure operators we bring sensing to the regions that need it most - one hazard program at a time.
Partner with us03 - The network
Built by many hands.
Every station is hosted by someone who chose to take part: a family, a school, a city. Together they form a network denser than any single institution could build alone.

04 - GeoShake · the first program
The first program: GeoShake.
Our earthquake network. A compact ground-motion sensor, the GeoShake T1, turns homes, schools and workplaces into seismic observatories that report to the platform around the clock - 500+ stations today.
- Instrument
- GeoShake T1 · quad-MEMS array
- Connectivity
- Wi-Fi, encrypted
- Power
- USB-C, under 1 W
- Firmware
- Open source (GPL-3.0)
Apps & live map
Earthquake alerts and live ground-motion data on iOS, Android and the web, with an open developer API for researchers and builders.
Integrations
Automatic responses once shaking is confirmed: gas shut-off, emergency lighting and rail slow-down through Home Assistant, Apple Home and industrial relays.
05 - How it works
Sense. Confirm. Protect.
Sense
Each station samples ground motion more than 100 times a second and flags unusual shaking on the device itself.
Confirm
Neighboring stations cross-check the signal, rejecting traffic, construction and quarry blasts.
Protect
Confirmed alerts reach phones, buildings and infrastructure, and verified shaking data supports faster recovery.
For earthquakes today the network’s median alert time is 2.3 seconds, typically 5-20 seconds before strong shaking arrives, depending on distance from the epicenter.
06 - Roadmap
Six hazards. One platform.
Each hazard gets its own program on the same platform and the same principle - dense, affordable, hosted by the people it protects. Earthquakes are live; the rest follow in order.
Live
Earthquakes
GeoShake: ground-motion sensing and early warning, 500+ stations reporting.
In development
Tsunamis
Extending the earthquake network to coastal warnings: from the first shaking to the arrival of the sea.
Planned
Volcanic eruptions
Monitoring tremor and ground movement around active volcanoes.
Planned
Floods
Measuring rainfall and river levels in the places that flood first.
Planned
Landslides
Detecting slope movement and saturated ground on vulnerable hillsides.
Planned
Wildfires
Sensing heat, smoke and dryness where forests meet settlements.
07 - Mission before margin
A company that exists for its mission.
Sensory Earth is a company, but profit is not its purpose. The income it earns keeps the network growing, maintained and independent.
- 01
Instruments within reach
Sensors priced so that households, schools and small communities can take part.
- 02
Sponsorship
Organizations and philanthropists fund arrays of stations where they are needed most.
- 03
Services for institutions
Infrastructure operators, insurers and public bodies pay for data, integrations and verified event reports, including data for parametric insurance.
Open by default
Firmware and software are published openly, so the network can be examined, improved and trusted.
Affordable by design
Low-cost instruments mean taking part is not reserved for wealthy places.
In service of the public
The network exists to protect people. Commercial work sustains that purpose; it never replaces it.
Science with communities
We work alongside the people who host our sensors, not merely in their neighborhoods.
08 - Distributors and partners
From the Baltic to the Caribbean.
GeoShake reaches the people who host it through regional partners and distributors who know their markets: in Europe, Türkiye, China and the Caribbean. The company itself is registered in London.
