Convolutional Neural Network for Earthquake Detection and Location

Thibaut Perol, Michaël Gharbi, Marine Denolle

摘要:

最近在美国中部诱发地震活动的演变要求详尽的目录,以改善地震危险性评估。在过去的几十年里,地震资料的数量呈指数级增长,这就需要有效的算法来可靠地检测和定位地震。今天最复杂的方法是扫描过多的连续地震记录,寻找重复的地震信号。在这项工作中,我们利用人工智能的最新进展,提出了ConvNetQuake,这是一种高度可扩展的卷积神经网络,用于从单个波形中进行地震检测和定位。我们应用我们的技术来研究诱发地震在俄克拉荷马州(美国)。我们探测到的地震比俄克拉荷马地质调查局以前记录的多20倍。我们的算法是数量级的速度比既定的方法。

英文摘要:

The recent evolution of induced seismicity in Central United States calls for exhaustive catalogs to improve seismic hazard assessment. Over the last decades, the volume of seismic data has increased exponentially, creating a need for efficient algorithms to reliably detect and locate earthquakes. Today's most elaborate methods scan through the plethora of continuous seismic records, searching for repeating seismic signals. In this work, we leverage the recent advances in artificial intelligence and present ConvNetQuake, a highly scalable convolutional neural network for earthquake detection and location from a single waveform. We apply our technique to study the induced seismicity in Oklahoma (USA). We detect 20 times more earthquakes than previously cataloged by the Oklahoma Geological Survey. Our algorithm is orders of magnitude faster than established methods.
