An Overview of Traditional and Next-Generation Earthquake Early Warning Systems

Abstract

The Earthquake Early Warning System generates rapid and effective warnings after detecting an earthquake, before the arrival of destructive waves to the areas that may be affected. In this way, it is aimed to minimize the loss of life and property. In this study, traditional early warning systems that are frequently used in the world are discussed. The details of the next-generation early warning system, which has recently produced successful outputs, are discussed, and its advantages over traditional early warning systems are mentioned. The recent developments of this system are also analyzed. Next-generation early warning systems consist of a new array-based algorithm composed of two modules for real-time epicenter detection. The detection of an earthquake occurring in the Marmara Sea (Türkiye) with a next-generation early warning system using array-based location methodology is given as an example. Next-generation early warning systems have advantages over traditional ones, such as lower cost and time gains of up to minutes.
