Özet

The anticipated major earthquake in the Sea of Marmara presents significant risks due to the dense population and important infrastructure systems living in the region. Earthquake Early Warning (EEW) Systems can play an important role in reducing these risks. In this study, in addition to the existing EEW systems serving the infrastructure, a hybrid early warning model integrated with mosque loudspeakers that have the potential to warn residents is proposed. The system is based on the principle of announcing from mosque loudspeakers within the district borders through the mufti offices by evaluating the seismic data provided by the AFAD infrastructure. Simulations indicate that the proposed system is particularly effective in residential areas beyond 45 km and that a gain of 4.9 to 42.8 seconds can be achieved in warning time. However, it was observed that warnings given to people in areas closer than 45 km would be ineffective due to the rapid arrival of P waves. The novelty of this study is that it increases the effectiveness of early warning in areas where access to traditional infrastructure is limited by integrating the widely used and extensively used mosque loudspeakers into the EEW system. Thus, the model used has the potential to reduce deaths, thanks to the wide geographical spread of mosques. The success of the system is directly affected by factors such as power outages, public awareness, and communication infrastructure. Therefore, the effectiveness of the system can be increased if it is supported by hybrid models that include mobile apps, SMS, and TV broadcasts. In addition, the reliability and applicability of the system should be tested in a selected pilot area. In conclusion, a hybrid EEW system, where the main instrument of the announcement channel is the mosque loudspeakers, offers a powerful alternative to provide early warning to the people of the region surrounding the Marmara Sea.
