Catalogs of P-phase and H-wave sources located by the MAHY Autonomous Hydrophones (AuH)

Close to Mayotte Island, a small volcano named Fani Maore was discovered in 2019. The sudden seismicity it triggered led to the creation of the REVOSIMA group and cruises, aiming at monitoring the activity of the volcano. Among the deployed sensors, MAHY, a network of four Autonomous Hydrophones (AuH), was deployed in 2020. Hydrophones enable to monitor many sources. Two signals of interest are the pupose of this dataset: P-phases, which are compressional seismic waves generated by earthquakes, and H-waves, which are in this case hydroacoustic signals generated by lava-seawater interaction.
Using the hydroacoustic picking model TiSSNet and the associator TAPAAs, a catalog was automaticaly created for each of these signal types.

2019年，科研人员在马约特岛（Mayotte）附近海域发现一座名为法尼·马奥雷（Fani Maore）的小型火山。该火山诱发的突发性地震活动，推动了REVOSIMA工作组与科考航次的组建，其宗旨为对该火山的活动进行长期监测。在此次布设的传感器阵列中，由四台自主水听器（Autonomous Hydrophones，AuH）组成的MAHY组网系统于2020年完成部署。水听器可实现对多类信号源的监测。本数据集的核心研究对象为两类目标信号：一类是由地震激发的压缩地震波P波（P-phases），另一类是本场景下由熔岩与海水相互作用产生的水声信号H波（H-waves）。研究团队借助水声信号拾取模型TiSSNet与关联器TAPAAs，自动生成了针对这两类信号的分类目录。
