e-QUAKE-SMART for BUILDINGS: Complicated early warning and general precaution systems can be designed for cities or geographical regions. E-QUAKE-SMART, on the other hand, is rather a less complicated, easy-to-use earthquake warning and automatic reaction system, much more aims to trigger basic precaution reactions in a building when it senses excessive shaking.

RECORDING DURING AN EARTHQUAKE: In addition to the early and emergency warning solution, the system automatically switches to recording mode in case of an earthquake, records the floor accelerations, top floor accelerations, and displacements of the building according to the sensor locations. The shaking level of the building during an earthquake can be viewed and analyzed in real-time from the control panel or via the web-based interface.

Seconds Matter!

P and S waves: When earthquake waves start propagating from their center and reach a certain location on earth, they are sensed in 2 different types, called P waves and S waves.  As P waves move faster, they arrive at a certain location earlier than the S waves. The time difference between the arrival of P and S waves increases, as the distance from the center of the earthquake increases. Early Warning Systems are based on sensing the smaller amplitude P-waves, seconds before the higher amplitude S waves arrive, and generating a warning in terms of seconds before the mainshock strikes, which may be very important for taking a precaution.
