The National earthquake information center usually records over 20000 earthquakes around the world every year. Earthquakes are one of the worst disasters that lead to heavy loss of life and property. The key factor to reduce earthquake losses is by early detection and alerting.

Well we hereby develop a smart earthquake monitoring and alerting system that senses earthquake tremors and alerts users before the actual earthquake hits using buzzer as well as instant SMS alert remotely. The system makes use of an STM32 ARM controller board to run the system. We hereby use a vibration sensor, GSM module, LCD display, buzzer, push buttons and supporting circuitry to develop this system.

The system first allows user to select settings or start monitoring. This is displayed to user on LCD display and operated by user using push buttons. The user can register 3 contact numbers of authorized contact number through the settings options. The system stores these 3 contact numbers on which it will be sending SMS alerts on detection.

After settings are completed the user may set the system to monitoring state. In this state the system constantly monitors for earthquakes. The STM32 controller constantly keeps monitoring the vibration sensor signals. In case a vibration is detected the sensor sends a signal output which is detected by the controller.

The controller now operates the buzzer as to sound an alert and displays the same on LCD display. Also the controller communicates with the GSM module to send 3 SMS alerts. 3 SMS are sent consequently to the 3 registered contact numbers stored in the system during the settings phase. The system thus allows for early detection of earthquake vibrations and sends alerts to multiple people for instant broadcasting of the earthquake.
