An Open Dataset for Deep Learning-based Earthquake Detection using MEMS Sensors

초록

Due to the high population density and economic value of contemporary cities, earthquakes inflict greater damage on these cities. Consequently, the importance of quick earthquake early warning (EEW) is expanding, yet it is challenging to create a dense seismic monitoring network due to high installation and management costs. In order to overcome such limitations, MEMS sensors to monitor earthquakes and artificial intelligence (AI) technologies to analyze massive earthquake monitoring data are widely used today. In AI-based earthquake detection, the key to accurate detection is the use of sufficient data that accurately represents the various earthquake patterns. Unfortunately, how-ever, there is no publicly accessible database containing IoT-based seismic data. This is the result of relatively short research efforts. During the last two years of operation of CrowdQuake, a MEMS-based earthquake detection system, we collected earthquake and non-earthquake events, as well as normal noise data, which was greatly useful to improve the accuracy of AI models. As a result, we present an open dataset that is publicly available for MEMS-based earthquake detection research. © 2022 IEEE.
