How Does an Earthquake Warning System with Electronic Sirens Work?

Dozens of earthquakes occur around the world every day. Fortunately, most of them are too small to seriously jeopardise human activities. A severe problem arises only with a massive earthquake of great intensity.

The exact moment when a strong earthquake hits cannot be predicted yet. Therefore, it is even more critical to build a sufficiently fast, effective, and efficient warning system in endangered areas, bringing people valuable seconds to rescue their lives and property.

Description of the earthquake warning system solution

The basis of early earthquake warning systems is formed by reliable seismic sensors that can detect seismic waves and then, after the immediate evaluation, automatically activate a warning signal. It will provide people in the endangered area with valuable seconds for their rescue.

Seismic sensors are connected directly to an electronic siren, which is automatically activated in dangerous earth tremors. The system is automated and independent, so it works even in case of a power failure, which is a common side effect of earthquakes. Large systems are equipped with Vektra® software applications (SCADA, Warning, and Notification). When sensors detect dangerous earthquake activity (continuously monitored by Vektra® SCADA), all sirens are automatically activated (Vektra® Warning). Simultaneously, all first responders are notified by voice or text of the impending danger (Vektra® Notification).

Specialised sensors

Seismic sensors are installed in the lowest parts of buildings (such as basements) and monitor seismic waves. When dangerous seismic waves are detected, the sensors immediately and automatically activate a warning system. They are connected directly to an electronic siren and transmit the acquired data to the control centre.

02

Electronic sirens

After detecting dangerous seismic activity, electronic sirens immediately and automatically issue a warning signal. Their most significant advantage is that they cover a large area and deliver a warning message to the population in an endangered area as soon as possible. After the initial tremors have subsided, voice messages can be used to coordinate the affected people and assist in rescue operations. The electronic siren system can be activated individually or in groups from the control centre, independent of the commercial infrastructure. With solar power supply, sirens can be installed even in places without an external energy source.

03

Control centre

Equipped with the OCP16 control panel or Vektra® software applications, the control centre automatically activates warnings and notifications in an emergency. The entire technology is highly secure and fully backed up. From the control centre, it is also possible to start the system in other emergencies and disasters.

04

Communications infrastructure

Communications infrastructure provides high-speed communications between the control centre and other monitoring, warning, and notification systems. At the same time, it allows the connection of these systems with third-party systems.

05

Notified persons

All responsible persons and emergency units are informed of an emergency by telephone or through SMS and are summoned to work and rescue operations.

Who Is an Earthquake Warning System Designed For?

Telegrafia’s earthquake warning systems are designed to protect the public, large areas, and critical infrastructure in regions exposed to earthquake risk. These professional solutions integrate seismic detection, electronic sirens, control centers, and communication and notification systems.

The system can be tailored to the needs and risk level of each location and is especially suitable for:

  • Cities and municipalities: to quickly alert the public through electronic sirens installed at strategic locations.
  • Civil defense and government agencies: to automate earthquake warnings and support a coordinated emergency services response.
  • Critical infrastructure: to protect essential facilities and services and activate emergency procedures when dangerous seismic activity occurs.
  • Industrial plants and large facilities: to alert employees and visitors and, when necessary, automatically activate safety measures through SCADA control systems.

The earthquake warning system can be designed as a local solution or as part of a broader earthquake early warning system with multiple sensors, electronic sirens, and control points.
