Why it matters

Those first seconds are yours.

Every earthquake sends a fast, harmless wave (P) ahead of the slow, destructive one (S). The T1 catches the P-wave the instant it arrives and warns you often 5 to 20 seconds before the shaking reaches your street.

  • Drop, cover, and hold before it hits
  • Alerts tuned to your home and radius
  • Auto-reconnects the moment your connection returns

Under the hood

Serious hardware. Simple to live with.

A dual-core processor paired with an array of four industrial 6-axis IMUs reads the ground more than 100 times a second and streams over secure MQTT. No subscription, no cloud lock-in the firmware and enclosure designs are fully open.

  • Plug in, connect with your phone live in 2 minutes
  • Free over-the-air firmware updates forever
  • Privacy-first: only acceleration data ever leaves the device

How a shake becomes an alert.

One device sensing something is a clue. Many devices agreeing is an earthquake.

01

Detects

Four accelerometers listen to the ground non-stop. A sudden jolt fires the on-device STA/LTA trigger the standard method in seismology within milliseconds.

02

Verifies

Your trigger is matched in the cloud with neighboring devices in space and time. Only an event that spreads at real seismic-wave speed across multiple homes counts a passing truck or a slammed door doesn't.

03

Shows

The verified event lands on the live map with its location and intensity wave spread and affected stations, in real time, right in your browser.

By design, a single device never raises the alarm alone. The decision comes from the shared physics of many devices that's what keeps false alarms out.

Your sensor doesn't protect only your home. It protects everyone connected to the network.

Works with Google Home

Your home is now on the network.

When the GeoShake network confirms an earthquake within 300 km of your T1, your home hears it: lights on, a spoken announcement, a scene of your choice. Certified for Google Home, available as an Alexa skill (amazon.com), native in Home Assistant, direct in Smart Life.

Google Home, certified

Link your GeoShake account in the Google Home app. An Earthquake sensor appears; build a routine that starts when it turns on. No hub.

Amazon Alexa

Enable the GeoShake skill in the Alexa app: a network-confirmed earthquake starts your Alexa routine. For now, amazon.com accounts, in English. Set it up →

Home Assistant

Native integration via HACS, version 0.3.0, with a 300 km radius from your home location. Mirror it into Apple Home through the HomeKit Bridge.

Smart Life & Tuya

In Central Europe, no hub needed: scan one code and the T1 appears in Smart Life, ready for Tap-to-Run scenes.

Smart-home automations are an extra notification layer, not a life-safety system. Always rely on official warnings and the GeoShake app alert first.

Science Mode

A real seismograph under the hood.

In normal operation the T1 sends only a compact summary trigger time and peak acceleration. Switch on Science Mode and it records the full raw waveform: all three axes at ~110 Hz, full resolution.

  • Inspect P and S wave arrivals, amplitude and duration on real recordings
  • Open analysis toolkit process the data with Python (numpy, scipy, matplotlib)
  • Made for classrooms, universities, clubs and curious minds

What hosts say
“I was in Vega Alta when I got the alert for the magnitude 4.8 earthquake in the southwest, 15 seconds before the shaking reached my home.”
Richard Córdova · Puerto Rico
“I mounted it in the basement and forgot about it until a magnitude 4.2 hit 60 km away and my phone buzzed before anything started moving.”
Nikos Vassiliou · Athens
“I installed one at my parents' place in Oaxaca. Watching the network grow week by week is genuinely reassuring.”
Mariana Morales · Oaxaca
