1.EQ guard, an earthquake early warning device with a built-in sensor.

The EQ guard uses a high-performance built-in sensor to notify you of an earthquake before a large tremor occurs.

Product features
  1. A built-in sensor directly detects the preliminary tremors of an earthquake and immediately notifies the occurrence of an earthquake.
  2. English, Spanish, Arabic, Russian, Persian, Turkish, Chinese, Korean
    It supports 10 languages, Indonesian and Portuguese.
  3. It can be displayed on the map in real time on the PC screen.
  4. Seismic intensity forecasts and grace times at each site can be displayed and managed in a list.

Community alarm system
The EQ guard works by itself. At the same time, you can install multiple units and connect to a data center via the Internet to build a regional earthquake / tsunami warning system.
When an earthquake occurs, the EQ guard near the epicenter detects the P wave and sends the information to the data center. The epicenter is identified based on the information collected in the data center, and the magnitude, depth, and latitude / longitude are delivered to each terminal. The terminal calculates the seismic intensity and the number of seconds of arrival from the epicenter information and issues an alarm.

The information gathered from each EQ guard can display real-time waveforms through the server.

<Case of introduction overseas>

 Since 2019, we have been collaborating with the Earthquake Research Institute to install an EQ guard in the Tekeli area in 2021 and to link it with smartphones.
